Genética de la resistencia al complejo Phyllachora maydis Maubl., Monographella maydis Müller &amp; Samuels y Coniothyrium phyllachorae Maubl., en diversos genotipos de maíz (Zea mays L.).
Provedor de dados: 32
Autores: Hernández Ramos, Lervin.
El complejo de la mancha de asfalto del maíz, inducido por los hongos Phyllachora maydis y Monographella maydis, es una enfermedad de importancia económica en México y Centroamérica, debido a que provoca severas pérdidas en el rendimiento y deteriora la calidad del forraje. El mejoramiento genético de la resistencia del hospedante a través de la generación de genotipos resistentes representa la medida de control más eficiente para el control de la enfermedad. Se conoce poco respecto a la base genética de la resistencia al CMA, por lo cual se determinó la Aptitud Combinatoria General (ACG) y Aptitud Combinatoria Especifica (ACE) de 18 líneas endogámicas S7 mediante el Modelo I de frecuencias fijas de Griffing, bajo el Método II que incluyó las 18 líneas más...

Protective effect of an antimicrobial peptide from Mytilus edulis chilensis expressed in Nicotiana tabacum L.
Provedor de dados: 69
Autores: Arenas,Gloria; Marshall,Sergio H.; Espinoza,Valeria; Ramírez,Ingrid; Peña-Cortés,Hugo.
A "defensin-like" antibacterial peptide from Mytilus edulis chilensis, was sub-cloned into a binary vector for expression in plant tissues. The resulting new clone was electroporated into A. tumefaciens to transform tobacco plants. The presence of the construct in transgenic tobacco lines was demonstrated through RT-PCR, Northern and Western blots. Transformed positive plants were selected and grown for challenging. Tobacco leaves were infiltrated with Pseudomonassyringae pv. syringae and visual lesions determined at different times post-exposure. Of seven plants exposed, four gave variable protection up to seven days post-infection while one of them appears to be fully protected. These results suggest that defensin-like antimicrobial peptides from...

Asian soybean rust (ASR), caused by the phytopathogenic fungi Phakopsora pachyrhizi, has caused large reductions in soybean (Glycine max) yield in most locations in Brazil where it has occurred since it was first reported in May 2001. Primary efforts to combat the disease involve the development of resistant cultivars, and four dominant major genes (Rpp1, Rpp2, Rpp3 and Rpp4) controlling resistance to ASR have been reported in the literature. To develop new long-lasting soybean ASR resistance genes, we used field experiments to assess ASR leaf lesion type in 11 soybean genotypes (BR01-18437, BRS 184, BRS 231, BRS 232, BRSGO Chapadões, DM 339, Embrapa 48, PI 200487, PI 230970, PI 459025-A and PI 200526) and the 55 F2 generations derived from their...

An AFLP marker linked to the Pm-1 gene that confers resistance to Podosphaera xanthii race 1 in Cucumis melo
Provedor de dados: 74
Autores: Teixeira,Ana Paula Matoso; Barreto,Fatima Aparecida da Silva; Camargo,Luis Eduardo Aranha.
Brazil produced 330,000 metric tons of melons in 2005, principally in the Northeast region where one of the most important melon pathogens is the powdery mildew fungus Podosphaera xanthii. The disease is controlled mainly by incorporating single dominant resistance genes into commercial hybrids. We report on linkage analysis of the Pm-1 resistance gene, introgressed from the AF125Pm-1 Cantalupensis Charentais-type breeding line into the yellow-fleshed melon (Group Inodorus) breeding line AF426-S by backcrossing to produce the resistant line AF426-R, and the amplified fragment length polymorphism (AFLP) marker M75/H35_155 reported to be polymorphic between AF426-S and AF426-R. Segregation analysis of M75/H35_155 using a backcross population of 143 plants...

Citrus is the most important fruit crop in Brazil and Citrus tristeza virus (CTV) is considered one of the most important pathogens of citrus. Most citrus species and varieties are susceptible to CTV infection. However, Poncirus trifoliata, a close relative of citrus, is resistant to the virus. In order to better understand the responses of citrus plants to the infection of CTV, we constructed expressed sequence tag (EST) libraries with tissues collected from Poncirus trifoliata plants, inoculated or not with Citrus tristeza virus at 90 days after inoculation, grafted on Rangpur lime rootstocks. We generated 17,867 sequence tags from Poncirus trifoliata inoculated (8,926 reads) and not (8,941 reads) with a severe CTV isolate. A total of 2,782 TCs...

Sources of resistance against the Pepper yellow mosaic virus in chili pepper
Provedor de dados: 75
Autores: Bento,Cíntia dos S; Rodrigues,Rosana; Zerbini Júnior,Francisco Murilo; Sudré,Cláudia P.
The Pepper yellow mosaic virus (PepYMV) naturally infects chili and sweet pepper, as well as tomato plants in Brazil, leading to severe losses. This work reports the reaction to the PepYMV of 127 Capsicum spp. accessions, aiming at identifying resistance sources useful in breeding programs. The experiment was carried out in a completely randomized design, with eight replications, in greenhouse conditions. Plants were protected with an insect-proof screen to avoid virus dissemination by aphids. Leaves of Nicotiana debneyi infected with the PepYMV were used as the inoculum source. Plants were inoculated with three to four fully expanded leaves. A second inoculation was done 48 hours later to avoid escapes. Only the youngest fully expanded leaf was...

Reaction of Capsicum peppers commercialized in the Federal District to bacterial wilt
Provedor de dados: 75
Autores: Rossato,Maurício; Santiago,Thais R.; Lopes,Carlos Alberto.
ABSTRACT In Brazil, the bacterial pathogens Ralstonia solanacearum and R. pseudosolanacearum cause substantial losses by inducing bacterial wilt on several solanaceous crops; R. pseudosolanacearum is the main species associated with peppers (Capsicum sp.). To verify the bacterial wilt reaction on Capsicum peppers commercialized in the Federal District (DF), fruits of several genotypes within this genus were collected from six different fairs distributed in the satellite cities of Gama, Sobradinho and Guará. Seedlings with four true leaves derived from seeds extracted from such fruits were root inoculated with 108 CFU/mL with a representative isolate of R. pseudosolanacearum (race 1, biovar 3, phylotype I, sequevar 18). The evaluated species were: Capsicum...

Provedor de dados: 14
Autores: SOARES, D. J.
O mofo-cinzento da mamoneira é uma das doenças econômicamente mais importantes desta cultura e, quando sob condições favoráveis, pode resultar em elevadas perdas de produção. Pouco se conhece sobre o comportamento de híbridos comerciais de mamoneira frente a essa doença. Os híbridos AG-IMA, AKB-02, MIA e TAMAR foram avaliados quanto a sua reação ao mofo-cinzento, em condições controladas, utilizando-se a técnica de frutos destacados. Com base nos resultados obtidos no presente estudo, os híbridos AKB-02, MIA e TAMAR foram considerados altamente suscetíveis e o híbrido AG-IMA foi considerado suscetível. Dessa forma, uma vez que todos os materiais avaliados foram considerados suscetíveis, a pulverização preventiva com fungicidas continua sendo essencial para...

A bovinocultura de corte, principal atividade economica da sub-regiao da Nhecolandia, do Pantanal, devido, principalmente, a problemas nutricionais, apresenta baixos indices de produtividade. A alimentacao dos bovinos e constituida de pastagens nativas, geralmente de produtividade ou valor nutritivo baixos e de baixa disponiblidade nos meses de cheia. Face a esta situacao, o CPA-Pantanal, entre 1980 e 1985, realizou um experimento de introducao e avaliacao da forrageira em area de "cordilheira" desmatada com o objetivo de identificar gramineas e leguminosas adaptaveis as suas condicoes ecologicas. As forrageiras (43 gramineas e 123 leguminosas) foram plantadas em parcelas de 1,5 x 3,0 m. Foram utilizadas duas parcelas, por local, para cada especie, uma com...

The present study identifies quantitative trait loci (QTLs) in response to an experimental infection with the parasite responsible for bonamiosis, Bonamia ostreae, in two segregating families of the European flat oyster, Ostrea edulis. We first constructed a genetic-linkage map for each studied family and improved the existing genetic-linkage map for the European flat oyster with a set of SNP markers. This latter map now combines the best accuracy and the best estimate of the genome coverage available for an oyster species. Secondly, by comparing the QTLs detected in this study with those previously published for O. edulis in similar experimental conditions, we identified several potential QTLs that were identical between the different families, and also...

Enhancing resistance to Vibrio aestuarianus in Crassostrea gigas by selection
Provedor de dados: 5
Autores: Dégremont, Lionel; Azéma, Patrick; Maurouard, Elise; Travers, Marie-agnes.
Ostreid herpesvirus 1 (OsHV-1) and Vibrio aestuarianus are the two main pathogens affecting the production of French oyster (Crassostrea gigas). The absence of genetic correlation between the two diseases is promising for the development of stocks with dual resistance. Using unselected and selected oysters concerning enhanced resistance to OsHV-1 infection, we investigated the first generation of mass selection and the response to selection to increase the resistance to V. aestuarianus for two stocks. For each stock, four groups were produced in June 2013 using either parents unchallenged with the bacteria or counterparts that survived experimental infections by the bacteria. Thus, groups were unselected oysters for both pathogens, selected for either the...

Autores: De Decker, Sophie.
The New-Caledonian shrimp industry is based on the controlled reproduction of the shrimp Litopenaeus stylirostris, a species which was introduced in the 80s. The major difficulty to which the industry has been faced for 10 years is the occurrence of the “Syndrome 93”, which corresponds to mortality phases when the temperature falls down in April-May-June. This mortality is associated to the pathogenic bacteria Vibrio penaecida. An experiment of genetic selection based on the criterion ofsurvival to Syndrome 93 has been conducted at the Laboratory of Aquaculture of New Caledonia. The 3rd selected generation had demonstrated very encouraging results (survival rates improved by around 20% in experimental infections with V. penaeicida). These results have not...

Autores: Dégremont, Lionel; Morga, Benjamin; Trancart, Suzanne; Pépin, Jean-francois.
The ostreid herpesvirus(OsHV-1) is one of the major diseases that affect the Pacific oyster Crassostrea gigas. Selective breeding programs were recently shown to improve resistance easily to OsHV-1 infections in spat, juvenile, and adult oysters. Nevertheless, this resistance has never been investigated in larvae, whereas this developmental stage has crucial importance for the production of commercial hatcheries, as well as explaining the abundance of spatfall. A first trial tested several viral suspensions at several concentrations using contaminated water with OsHV-1 in 4- and 10-day-old larvae that we reproduced from an unselected broodstock. In follow up on the results, one viral suspension at a final concentration of 10+6 OsHV-1 DNA copies per L was...

The Manila clam Ruditapes philippinarum, a major cultured shellfish species, is threatened by infection with the microparasite Perkinsus olseni, whose prevalence increases with high water temperatures. Under the current trend of climate change, the already severe effects of this parasitic infection might rapidly increase the frequency of mass mortality events. Treating infectious diseases in bivalves is notoriously problematic, therefore selective breeding for resistance represents a key strategy for mitigating the negative impact of pathogens. A crucial step in initiating selective breeding is the estimation of genetic parameters for traits of interest, which relies on the ability to record parentage and accurate phenotypes in a large number of...

Synthesis of the “PLAN DE SAUVEGARDE” using selected all-triploid oysters to reduce the shortage of spat in France due to OsHV-1–associated mortality in Crassostrea gigas
Provedor de dados: 5
Autores: Dégremont, Lionel; Maurouard, Elise; Ledu, Christophe; Benabdelmouna, Abdellah.
Due to massive mortality of Crassostrea gigas spat in France since 2008, a “plan de sauvegarde” was set up from 2011 to 2014 (hereafter referred to as PS1 to PS4), in order to reduce the shortage of spat. This plan involved the participation of commercial hatcheries, the French Research Institute for Exploitation of the Sea (Ifremer), and the Direction des Pêches Maritimes et de l'Aquaculture (DPMA) of the French Ministry of Agriculture. It was based on selecting diploid lines of C. gigas for their higher resistance to the oyster herpesvirus OsHV-1 (2nR group), and one of these lines was subsequently tetraploidized (4nR group). Both the 2nR and 4nR groups were produced by Ifremer, and then transferred to commercial hatcheries that produced the selected...

Is horizontal transmission of the Ostreid herpesvirus OsHV-1 in Crassostrea gigas affected by unselected or selected survival status in adults to juveniles?
Provedor de dados: 5
Autores: Degremont, Lionel; Guyader, Tanguy; Tourbiez, Delphine; Pepin, Jean-francois.
Massive mortality outbreaks, mostly affecting spat Crassostrea gigas, have been reported in France since 2008. Disease investigations revealed that most of the mortality events are related to the detection of the Ostreid herpesvirus 1 (OsHV-1 μVar). Meanwhile, selection to improve the survival in juvenile C. gigas has been successfully implemented in this context and selected oysters were found disease-resistant to OsHV-1 infection. This paper reports the first investigation of the horizontal transmission of the disease throughout cohabitation trials within batch and between batches using unselected and selected oysters for their higher survival. Two batches, unselected (AC) and selected (AR), were produced in February 2009 and deployed in the field in...

Combining Two-Stage Testing and Interval Mapping Strategies to Detect QTL for Resistance to Bonamiosis in the European Flat Oyster Ostrea edulis
Provedor de dados: 5
Autores: Lallias, Delphine; Gomez-raya, L.; Haley, C. S.; Arzul, Isabelle; Heurtebise, Serge; Beaumont, A. R.; Boudry, Pierre; Lapegue, Sylvie.
We have identified quantitative trait loci (QTL) in the flat oyster (Ostrea edulis) for resistance to Bonamia ostreae, a parasite responsible for the dramatic reduction in the aquaculture of this species. An F-2 family from a cross between a wild oyster and an individual from a family selected for resistance to bonamiosis was cultured with wild oysters injected with the parasite, leading to 20% cumulative mortality. Selective genotyping of 92 out of a total of 550 F-2 progeny (i.e., 46 heavily infected oysters that died and 46 parasite-free oysters that survived) was performed using 20 microsatellites and 34 amplification fragment length polymorphism primer pairs. Both a two-stage testing strategy and QTL interval mapping methods were used. The two-stage...

Evidence of herpesvirus (OsHV-1) resistance in juvenile Crassostrea gigas selected for high resistance to the summer mortality phenomenon
Provedor de dados: 5
Autores: Degremont, Lionel.
During the MOREST project (2001–2006), oyster summer mortality was extensively investigated in Crassostrea gigas in France. However, significant increases in magnitude and geographic distribution of summer mortality episodes have been reported since 2008. This paper investigates the response to selection for survival, which was successfully performed between 2001 and 2003, in this new context. It also examines the relationship between the mortality and the three pathogens Vibrio aestuarianus, V. splendidus and the Ostreid herpesvirus 1 (OsHV-1). Three batches of juvenile (6-month-old) Crassostrea gigas were produced in February 2009 and tested in the field in the Marennes-Oléron Bay during summer (August and September) 2009: one control batch, one batch...

Breeding and Domestication of Eastern Oyster (  Crassostrea virginica  ) Lines for Culture in the Mid-Atlantic, Usa: Line Development and Mass Selection for Disease Resistance
Provedor de dados: 5
Autores: Frank-lawale, Anu; Allen, Standish K.; Degremont, Lionel.
A selective breeding program for Crassostrea virginica was established in 1997 as part of an initiative in Virginia to address declining oyster harvests caused by the two oyster pathogens Haplosporidium nelsoni (MSX) and Perkinsus marinus (Dermo). Housed in the Aquaculture Genetics and Breeding Technology Center (ABC), the objective of the program was to develop and disseminate disease-resistant lines that would enable an oyster culture industry. Today, culture of disease-resistant cultivars accounts formore than 90%of oyster production in the state, where 28.1 million half-shell oysters and 2 billion eyed larvae were sold in 2012. Results of our line development program as of 2006 are reported. Eight ABC lines from 3 genetic groups—East Coast (EC),...

Mass selection for survival and resistance to OsHV-1 infection in Crassostrea gigas spat in field conditions: response to selection after four generations
Provedor de dados: 5
Autores: Degremont, Lionel; Nourry, Max; Maurouard, Elise.
The ostreid herpesvirus 1 (OsHV-1) is one of the major pathogens affecting the Pacific oyster Crassostrea gigas, and numerous mortality outbreaks have been observed worldwide. We report the first results of our experimental breeding program using mass selection focused on survival and resistance to OsHV-1 after four generations of selection for two lines. These lines originated from two stocks of adult wild oysters sampled from the Marennes-Oléron Bay in 2008. Each line was spawned in February 2009 to produce the base populations. Both lines were then either protected from OsHV-1 or tested in the field in 2009 where they were exposed to OsHV-1. For each line during 2010 to 2013, one generation per year was produced using either the survivors of the...

Size and genotype affect resistance to mortality caused by OsHV-1 in Crassostrea gigas
Provedor de dados: 5
Autores: Degremont, Lionel.
As with summer mortalities reported in France between 2001 and 2006, mortality caused by the Ostreid herpesvirus 1 (OsHV-1) in Crassostrea gigas affects mostly juveniles, although adults can also be impacted to a small extent. This could suggest that both mortalities have similar causes and that establishment of resistance, in particular to the Ostreid herpesvirus 1 (OsHV-1), depends on either the size or the age of oysters. The present study reports an investigation of both size and age using three cohorts produced during winter and three produced during summer. Each cohort contained oysters genetically selected to be resistant or susceptible to the summer mortality phenomenon, as well as unselected control oysters. Any abnormal mortality was recorded...

Genetic improvement for disease resistance in oysters: a review
Provedor de dados: 5
Autores: Degremont, Lionel; Garcia, Celine; Allen, Standish K., Jr.
Oyster species suffer from numerous disease outbreaks, often causing high mortality. Because the environment cannot be controlled, genetic improvement for disease resistance to pathogens is an attractive option to reduce their impact on oyster production. We review the literature on selective breeding programs for disease resistance in oyster species, and the impact of triploidy on such resistance. Significant response to selection to improve disease resistance was observed in all studies after two to four generations of selection for Haplosporidium nelsoni and Roseovarius crassostrea in Crassostrea virginica, OsHV-1 in Crassostrea gigas, and Martelia sydneyi in Saccostrea glomerata. Clearly, resistance in these cases was heritable, but most of the studies...

This paper gives an overview of own experiences with respect to the impact of dietary conditions on the quality of postlarval penaeid shirmp. Direct nutrient-specific effects are documented for highly unsaturated fatty acid (HUFA), phosphatidyl choline (PC) and ascorbic acid (AA). Specific immunostimulants may also contribute to an improved stress resistance of the shrimp fry. Last, but not least, some emphasis is placed on the role of the microflora during the hatchery rearing, the possible reduction of bacteria in the live food adminstered, and the use of probionts through the diet.

Autores: Urashima,Alfredo Seiiti.
Resistant varieties have been the preferred means to control Magnaporthe grisea, the causal organism of the rice blast disease. The objective of this study was to examine the degree of diversity of the pathogen in different rice growing regions of São Paulo State, Brazil. Blast samples collected from rice varieties in three different regions (Tremembé, Mococa and José Bonifácio) were analyzed for race structure employing the Japanese rice differentials. The highest degree of virulence diversity was observed in Tremembé with 22 different races in three different varieties. Furthermore, no resistance gene in the Japanese differentials was effective to all isolates of M. grisea from São Paulo State.

This article summarizes a study of consumers' willingness to pay (WTP), in urban areas in Tennessee, Mississippi, and Michigan, for a powdery mildew resistant dogwood tree. Powdery mildew is a disease affecting flowering dogwoods that can limit growth, detract from the appearance, and may cause plant decline and death.  Study objectives were to provide information about consumers' WTP and to identify potential marketing strategies for the introduction of the disease-resistant tree. On average, survey respondents indicated they are willing to pay a $13.35 premium for a flowering dogwood tree which is resistant to powdery mildew. Regression results led to inferences that the presence of dogwoods in a respondent's yard, presence of dogwoods infected with...

This report reviews the impacts of the Asian Maize Biotechnology Network (AMBIONET), organized by the International Maize and Wheat Improvement Center (CIMMYT) with funding from the Asian Development Bank to strengthen the capacity of public maize research institutions in China, India, Indonesia, Philippines, Thailand, and Vietnam to produce high-yielding, disease resistant, stress tolerant maize cultivars. It was found that, during its lifetime (1998-2005), AMBIONET clearly benefited researchers and institutions in participating countries, as well as CIMMYT. In addition, there was good progress toward developing improved cultivars. Asian farmers are just beginning to gain from the work, but their future benefits will likely pay for AMBIONET’s relatively...

Provedor de dados: 124
Autores: Nogueira,Danilo Gustavo; Carvalho,Regis de Castro; Maluf,Wilson Roberto; Nogueira,Douglas Willian; Ticona-Benavente,César Augusto.
ABSTRACT  The aim of this study was to develop bell pepper hybrids with resistance to multiple pathogens and make inferences in regard to components of heterosis in hybrids obtained from lines presumed to be resistant to Pepper yellow mosaic virus (PepYMV), Phytophthora capsici, or Meloidogyne incognita. The studies were carried out in a greenhouse. We used ten lines, thirty experimental hybrids, and seven controls (Konan-R, Magali-R, Martha-R, Stephany, Mallorca, Magnata Super, and Criollo de Morelos-334). For all experiments, a randomized block design was used with three replications (with plots composed of 16 plants). For evaluation of the reactions to P. capsici and to PepYMV, the percentages of asymptomatic plants were considered. For evaluation of...

Disease resistance in sugarcane – An overview
Provedor de dados: 22
Autores: Sundar, A. Ramesh; Ashwin, N.M.R.; Barnabas, E. Leonard; Malathi, P.; Viswanathan, R.
Sugarcane is one of the important commercial crops cultivated world-wide both under tropical and sub-tropical conditions. The crop gains economic importance by virtue of its industrial potential in terms of products like crystal white sugar, bagasse, pressmud, power etc. Among the various production constraints of the crop, diseases are seen as a major threat for sustaining the productivity of sugarcane. Conventional Breeding is a lengthy process and it involves almost more than 10 years for the release of a commercial variety. Many varieties with superior agronomical traits have succumbed to diseases like red rot and smut during the course of cultivation, which hitherto at the time of release were rated to be resistant. The breakdown of disease resistance...

Aggressiveness between genetic groups I and II of isolates of Cercospora zeae-maydis
Provedor de dados: 63
Autores: Mathioni,Sandra Marisa; Carvalho,; Brunelli,Kátia Regiane; Beló,André; Camargo,Luis Eduardo Aranha.
For many years, the gray leaf spot disease (GLS) caused by the fungus Cercospora zeae-maydis Tehon &amp;amp; Daniels, was not considered an important pathogen of maize (Zea mays, L.) in Brazil. However, the recent adoption of agronomical practices such as no-tillage and cultivation under central pivot irrigation systems increased the incidence and severity to the extent that GLS is now one of the most important diseases of maize. Isolates of C. zeae-maydis can be distinguished by two genetic groups (I and II) based on AFLP markers and on polymorphisms of the ITS and 5.8S rDNA regions. Until now, however, the biological implications of this distinction remain unclear. This study investigated whether isolates from the two genetic groups differ in...

Inheritance of resistance to Fusarium oxysporum f. sp. phaseoli Brazilian race 2 in common bean
Provedor de dados: 63
Autores: Pereira,Mônica Juliani Zavaglia; Ramalho,Magno Antonio Patto; Abreu,Ângela de Fátima Barbosa.
Aiming to obtain information concerning the genetic control of the resistance of the bean (Phaseolus vulgaris L.) to the fungus Fusarium oxysporum f. sp. phaseoli, six crosses involving three resistant lines (Carioca MG, Esal 583 and Esal 566) and four susceptible to the fungus (Carioca, CNFC 10443, Uirapuru and Esal 522) were developed. The parental lines, the controls (Carioca MG and Carioca) and the F1, F2 and F3 generations were evaluated for reaction to Fusarium. For inoculation, root cuttings were immersed in a spore suspension. The evaluations were performed at 21 days after inoculation, by scale of notes ranging from 1.0, to 9.0 and genetic and phenotypic parameters were estimated. The heritability in the narrow sense ranged from 0.34 to 0.42 and...

Reaction of peach tree genotypes to bacterial leaf spot caused by Xanthomonas arboricola pv. prunis
Provedor de dados: 63
Autores: Medeiros,José Gilberto Sousa; Citadin,Idemir; Santos,Idalmir dos; Assmann,André Paulo.
Bacterial leaf spot (BLS), caused by Xanthomonas arboricola pv. pruni, is one of the most important diseases in Brazilian peach [Prunus persica (L.) Batsch] orchards and all over the world. The main objective of this study was to evaluate for BLS sensitivity of peach genotypes. Evaluations of thirty genotypes were carried out during the onset of the disease, for incidence, severity and defoliation, in field conditions. Pearson's correlations between the percentage of defoliation and leaf severity rating were performed. Genotypes 'Conserva 985', 'Conserva 871', 'Conserva 1129', and 'Tropic Snow', as resistance sources, and 'Conserva 1153', 'Bonão', 'Conserva 1125', and 'Atenas', as susceptible to BLS, were submitted to detached-leaf bioassay and greenhouse...

ABSTRACT: Despite important biotic stresses to common bean, Anthracnose (ANT) and Angular Leaf Spot (ALS) can cause losses of up to 80 % and occur in more than 60 countries around the world. Genetic resistance is the most sustainable strategy to manage these diseases. Thus, we aimed to (1) identify new SNP markers associated with ALS and ANT resistance loci in elite common bean lines, and (2) provide a functional characterization of the DNA sequences containing the identified SNP markers. We evaluated 60 inbred lines, under field conditions, which represent the elite germplasm developed by the Embrapa common bean breeding program across 22 years, in terms of severity of the ALS and ANT. The lines were genotyped with 5,398 SNPs. Then, a Mixed Linear Model...

Identification of rapd marker linked to blast resistance gene in a somaclone of rice cultivar Araguaia
Provedor de dados: 102
Autores: ARAÚJO,LEILA G.; PRABHU,ANNE S.; FILIPPI,MARTA C.
The gene Pi-ar confers resistance to Pyricularia grisea race IB-45 in a somaclone derived from immature panicles of the susceptible rice (Oryza sativa) cultivar Araguaia. RAPD technique was used to identify molecular markers linked to this gene utilizing bulked segregant analysis. Initially, the two parental DNAs from the resistant donor SC09 and 'Araguaia' were analyzed using random primers. Of the 240 primers tested, 203 produced amplification products. The two parental DNAs along with the resistant and susceptible bulks of F2 population were screened using 48 primers that differentiated resistant and susceptible parents. Even though eight primers differentiated the resistant bulk from the susceptible bulk, as well as somaclone SC09 and 'Araguaia', only...

Identification of Phaeoisariopsis griseola pathotypes from five States in Brazil
Provedor de dados: 102
Autores: SARTORATO,ALOISIO.
Due to the increased importance of angular leaf spot of common bean (Phaseolus vulgaris) in Brazil, monitoring the pathogenic variability of its causal agent (Phaeoisariopsis griseola) is the best strategy for a breeding program aimed at developing resistant genotypes. Fifty one isolates of P. griseola collected in five Brazilian States were tested on a set of 12 international differential cultivars in the greenhouse. When inoculated plants showed symptoms but no sporulation was observed, they were transferred to a moist chamber for approximately 20-24 h. After this period of time, if no sporulation was observed, the plants were considered resistant; otherwise, they were considered susceptible. From the fifty-one tested isolates, seven different pathotypes...

Genetic linkage map of Phaseolus vulgaris and identification of QTLs responsible for resistance to Xanthomonas axonopodis pv. phaseoli
Provedor de dados: 102
Autores: Santos,Amaury S.; Bressan-Smith,Ricardo E.; Pereira,Messias G.; Rodrigues,Rosana; Ferreira,Claudia F.
Common bean (Phaseolus vulgaris) cultivars with a high degree of resistance to Xanthomonas axonopodis pv. phaseoli (Xap) are not available in Brazil. Despite many studies, a low degree of resistance to Xap continues to exist due to its complex genetic inheritance, which is not well known. The objectives of this research were to complement a common bean genetic map based on the cross between a susceptible genotype 'HAB-52' and a resistant genotype 'BAC-6', and to map and analyze genomic regions (quantitative trait loci – QTLs) related to Xap resistance. Eleven linkage groups were determined using 143 RAPD markers, covering 1,234.5 cM of the genome. This map was used to detect QTLs associated with Xap resistance on leaves and pods. The averages of disease...

White mold caused by Sclerotinia sclerotiorum (Lib.) de Bary is a devastating disease that affects the common bean (Phaseolus vulgaris. L) crop worldwide. In Argentina, white mold has been detected in all bean production areas, reaching seed yield and quality losses up to 100% on susceptible common bean cultivars under favorable weather conditions. The aim of this study was to screen the physiological resistance of 20 common bean accessions to five genetically distinct isolates of S. sclerotiorum collected from the main common bean growing area of Argentina, using the greenhouse straw test. The white mold reaction was scored at 7, 14, and 21 days post-inoculation using a 1 (no disease symptoms) to 9 (severely diseased or dead plants) scale and the area...

Autores: Hamawaki,Osvaldo Toshiyuki; Hamawaki,Raphael Lemes; Nogueira,Ana Paula Oliveira; Glasenapp,Jacqueline Siqueira; Hamawaki,Cristiane Divina Lemes; Silva,Carolina Oliveira da.
ABSTRACT In Brazil, as the soybean crop expands the losses caused by nematodes as well as its incidence in producing areas have increased. Therefore, this work aimed to develop a non-genetically modified soybean which combines desirable traits as the root-knot nematode resistance, early-maturity, high seed yielding, and high oil and protein contents. Consequently, seeds (F2) derived from the double-crossing between (Guarani x Sambaiba) x (M Soy 6101 x Conquista) were bulked to grow the F3 generation. Following generations were advanced by the SSD method of breeding until F6. Thus, plants showing superior characteristics were planted separately to perform progeny tests and then advanced breeding lines were thoroughly tested and compared to standards in...
