Análise do genoma funcional de Arachis pintoi e desenvolvimento de novos marcadores moleculares. Repositório Alice
OLIVEIRA, J. C. de.
O amendoim forrageiro (Arachis pintoi Krapov. e W.C. Greg.) tem apresentado resultados importantes na pecuária por seu alto valor nutritivo, o que tem contribuído no aumento da produção de leite, ganho de peso no gado de corte e redução no tempo de abate em até nove meses. Além disso, seu uso como cobertura verde em consórcios com culturas comerciais tem contribuído na redução da erosão, manutenção da umidade do solo, ciclagem de nutrientes, fixação biológica de nitrogênio e baixas emissões de óxido nitroso. O uso de sequenciamento nova geração (NGS) pode auxiliar no conhecimento da biologia da espécie e desenvolvimento de novas cultivares. O objetivo do presente trabalho foi analisar o genoma funcional de Arachis pintoi por meio de dados de RNA-Seq e...

Developmental genetic analysis of fruit shape traits under different environmental conditions in sponge gourd (Luffa cylindrical (L) Roem. Violales, Cucurbitaceae) Genet. Mol. Biol.
Zhang,Sheng; Hu,Jin; Xu,Shengchun.
Analysis of genetic main effects and genotype × environment (GE) interaction effects for the fruit shape traits fruit length and fruit circumference in the sponge gourd (Luffa cylindrical (L) Roem. Violales, Cucurbitaceae) was conducted for diallel cross data from two planting seasons. A genetic model including fruit direct effects and maternal effects and unconditional and conditional variances analysis was used to evaluate the development of the fruit at four maturation stages. The variance analysis results indicated that fruit length and circumference were simultaneously affected by fruit direct genetic effects and maternal effects as well as GE interaction effects. Fruit direct genetic effects were relatively more important for both fruit shape traits...

Estimação de componentes da variância na cultivar de milho centralmex. Repositório Alice
VALOIS, A. C. C.; MIRANDA FILHO, J. B. de.
Utilizando dados de producao de graos advindos de quatro esquemas de cruzamentos na cultivar de milho (Zea mays L.) Centralmex, foram estimadas as variancias geneticas aditiva e dominante, variancia fenotipica, relacao, alem da depressao causada pela endogamia. A analise global realizada conduziu a obtencao dos valores de = 3,494 x 10-4 (kg/planta), = 0,6033 x 10-4 (kg/planta), relacao = 0,180 e depresao causada pela endogamia de 39,5%. Podem ter ocorrido possiveis distorcoes das estimativas devido a selecao para prolificidade, depressao pela endogamia, restricoes de frequencia genica e erro aleatorio associado as estimativas dos componentes de variancia.

Gene action and combining ability of yield and its components for late kharif season in okra (Abelmoschus esculentus (L.) Moench) Chilean J. Agric. Res.
Thirupathi Reddy,Medagam; Hari Babu,Kadiyala; Ganesh,Mutyala; Begum,Hameedunnisa; Dilipbabu,Jampala; Krishna Reddy,Reddivenkatagari Subbarama.
Knowledge on the genetic system controlling the quantitative traits is important for devising an efficient selection program through the use of a suitable mating design. Forty five Fis were generated by crossing 10 germplasm lines of okra (Abelmoschus esculentus (L.) Moench) namely P1(IC282248), P2(IC27826-A), P3(IC29119-B), P4(IC31398-A), P5(IC45732), P6(IC89819), P7(IC89976), P8(IC90107), P9(IC99716), and P10(IC111443) during summer 2009. Forty five F1s along with their 10 parents were evaluated in a randomized block design with three replicates during late kharif (August-November) 2009 at Vegetable Research Station, Hyderabad, Andhra Pradesh, India, for studying gene action and combining ability of yield and its components. Significant general combining...

GENES - a software package for analysis in experimental statistics and quantitative genetics - doi: 10.4025/actasciagron.v35i3.21251 Agronomy
Cruz, Cosme Damião; Universidade Federal de Viçosa.
GENES is a software package used for data analysis and processing with different biometric models and is essential in genetic studies applied to plant and animal breeding. It allows parameter estimation to analyze biological phenomena and is fundamental for the decision-making process and predictions of success and viability of selection strategies. The program can be downloaded from the Internet (http://www.ufv.br/dbg/genes/genes.htm or http://www.ufv.br/dbg/biodata.htm) and is available in Portuguese, English and Spanish. Specific literature (http://www.livraria.ufv.br/) and a set of sample files are also provided, making GENES easy to use. The software is integrated into the programs MS Word, MS Excel and Paint, ensuring simplicity and effectiveness in...

Genetic analysis and gene fine mapping of aroma in rice (Oryza sativa L. Cyperales, Poaceae) Genet. Mol. Biol.
Sun,Shu Xia; Gao,Fang Yuan; Lu,Xian Jun; Wu,Xian Jun; Wang,Xu Dong; Ren,Guang Jun; Luo,Hong.
We investigated inheritance and carried out gene fine mapping of aroma in crosses between the aromatic elite hybrid rice Oryza sativa indica variety Chuanxiang-29B (Ch-29B) and the non-aromatic rice O. sativa indica variety R2 and O. sativa japonica Lemont (Le). The F1 grains and leaves were non-aromatic while the F2 non-aroma to aroma segregation pattern was 3:1. The F3 segregation ratio was consistent with the expected 1:2:1 for a single recessive aroma gene in Ch-29B. Linkage analysis between simple sequence repeat (SSR) markers and the aroma locus for the aromatic F2 plants mapped the Ch-29B aroma gene to a chromosome 8 region flanked by SSR markers RM23120 at 0.52 cM and RM3459 at 1.23 cM, a replicate F2 population confirming these results. Three...

Genetic analysis of opaque2 modifier gene activity in maize endosperm. Repositório Alice
LOPES, M. A.; LARKINS, B. A..
Modifier genes have been described that convert the soft endosperm of opaque2 mutants to a hard, vitreous phenotype. The mode of action and the components of the genetic system involved in this seed modification ar poorly understood. We used genetic and biochemical analyses to investigate the number of opaque2 modifier genes, their mode of action and their relationship to the biochemical alterations in the modified endosperm. Using two inbred opaque2 lines, we showed that the activity of opaque2 modifier genes is influenced by the genetic back-ground. Analysis of segregating progenies and recombinant inbred lines derived from crosses between opaque2 and modified opaque2 genotypes indicated two independent loci affecting seed opacity and density. Consistent...

Molecular identification and mapping of a novel stripe rust resistance gene in wheat resistance line CH5389 Ciência Rural
Zhan,Haixian; Guo,Huijuan; Qiao,Linyi; Mao,Liping; Zhang,Shuosheng.
ABSTRACT: Stripe rust, caused by Puccinia striiformis is one of the most destructive diseases of wheat worldwide. CH5389 is a wheat-Thinopyrum intermedium derived line conferring stripe rust resistance. Genetic analyses of seedlings of F2 populations and F2:3 families developed by crossing CH5389 and susceptible common wheat revealed that stripe rust resistance in CH5389 was controlled by a single dominant gene that was designated YrCH5389. Eight SSR and EST-PCR polymorphic markers on chromosome 3AL were identified in F2 population of CH5389/Taichung29. The YrCH5389 was flanked by EST marker BE405348 and SSR marker Xwmc388 on chromosome 3AL with genetic distances of 2.2 and 4.6 cM, respectively. Comparative genomic analysis demonstrated that the...

Use of AFLPS to distinguish landraces of pejibaye (Bactris gasipaes) in brazilian Amazonia Scientia Agricola
Clement,Charles R.; Sousa,Nelcimar Reis; Rodrigues,Doriane Picanço; Astolfi-Filho,Spártaco; Moreno,Yolanda Núñez; Pascual,Vicente Torres; Rodríguez,Francisco Javier Gallego.
Although the first inhabitants of western Amazonia domesticated pejibaye (Bactris gasipaes Kunth, Palmae) or peach palm for its fruits, today it is widely planted for its heart-of-palm. Like other domesticates, pejibaye presents a complex hierarchy of landraces developed before the conquest of the Americas. The existence of three landraces (Pará, Solimões, Putumayo) was proposed along the Amazonas and Solimões Rivers, Brazil, based on morphological characteristics. There are some questions remaining about the intermediate landrace being an artifact of the morphometric analysis. AFLPs were used to evaluate the relationships among samples of these putative landraces. DNA was extracted from 99 plants representing 13 populations maintained in the Pejibaye...
