Analysis of genetic and epigenetic variation in in vitro propagated potato somatic hybrid by AFLP and MSAP marker
Provedor de dados: 69
Autores: Tiwari,Jagesh Kumar; Saurabh,Shaumaya; Chandel,Poonam; Singh,Bir Pal; Bhardwaj,Vinay.
Background: Genetic and epigenetic changes (DNA methylation) were examined in the tissue-culture propagated interspecific potato somatic hybrids between dihaploid Solanum tuberosum and S. pinnatisectum. Amplified fragment length polymorphism (AFLP) and methylation-sensitive amplified polymorphism (MSAP) were applied to detect the genetic and epigenetic changes, respectively in the somatic hybrids mother plants (1st cycle) and their regenerants (30th cycles sub-cultured). Results: To detect genetic changes, eight AFLP primer combinations yielded a total of 329 scorable bands of which 49 bands were polymorphic in both mother plants and regenerants. None of the scorable bands were observed in term of loss of original band of mother plant or gain of novel band...

Provedor de dados: 69
Autores: Diez-de-Medina Roldán,Sergio; Silva,Herman; Jeblick,Wolfgang; Nowik,Isabella; Modigell,Michael; Neuhaus,H. Ekkehard; Conrath,Uwe.
Background: Potato (Solanum tuberosum) is one of the most important sources of carbohydrates in human diet. Because of its high carbohydrate levels it recently has also received attention in biohydrogen production. To exploit the natural variation of potato with respect to resistance to major diseases, carbohydrate levels and composition, and capacity for biohydrogen production we analyzed tubers of native, improved, and genetically modified potatoes, and two other tuberous species for their glucose, fructose, sucrose, and starch content. Results: High-starch potato varieties were evaluated for their potential for Caldicellulosiruptor saccharolyticus-mediated biohydrogen production with Desirée and Rosita varieties delivering the highest biohydrogen...

Isolation and characterization of the tissue and development-specific potato snakin-1 promoter inducible by temperature and wounding
Provedor de dados: 69
Autores: Almasia,Natalia I; Narhirñak,Vanesa; Hopp,H. Esteban; Vazquez-Rovere,Cecilia.
Snakin-1 (StSN1) is a broad-spectrum antimicrobial peptide isolated from Solanum tuberosum. Homologous proteins have been identified in a wide range of species but there is no apparent consensus in the roles they play. A 1394 bp fragment of the 5&amp;#8217;upstream region of StSN1 gene, designated PStSN1, was isolated from the potato genome and sequenced. Bioinformatics analyses revealed a total of 55 potential regulatory motifs related to tissue-specificity, stress, defence and hormone responsiveness, among others. PStSN1 spatial and temporal activity was studied in transgenic Arabidopsis plants expressing a reporter gene under this promoter control (PStSN1::GUS). Histochemical staining revealed PStSN1::GUS expression in the root vasculature, cotyledons,...

Provedor de dados: 18
Autores: King, B.A.; Tarkalson, D.D.; Bjorneberg, D.L.; Taberna, J.P, Jr.
Conversion of potato ridged-row planting systems to wide bed planting systems may increase water and nitrogen use efficiency in commercial irrigated potato production systems by reducing the amount of irrigation water and water applied nitrogen fertilizer bypassing the potato root zone. Wide bed planting systems consist of planting multiple rows on a wide bed with 20 to 35% higher plant population than found in conventional ridgedrow planting systems. The objective of this study was to evaluate the effect planting system has on yield response of ‘Russet Norkotah’ potato to irrigation and nitrogen.  Planting systems evaluated were (1) conventional ridgedrow with dammer-diking; (2) 3.7 m wide bed with five potato rows spaced 66 cm between adjacent rows...

Management practices and sugar end potatoes
Provedor de dados: 18
Autores: Westermann, Dale T.
French fries processed from sugar end potatoes become  undesirably dark on one end while remaining  light on the other (fig. 1). The darkening is usually  caused by a higher concentration of reducing sugars  in the darkened end of the fry strip. Sugar ends are  associated with tubers that are pointed on the stem  end but also occur in ideally shaped tubers.  "Translucent end," "jelly end," and "sugar end"  describe the same physiological tuber problem. Translucent  end tubers with high levels of sugars develop  jelly end rot after progressive tissue breakdown  occurs. The Russet Burbank variety is particularly  susceptible to sugar end formation when subjected to  water and heat stress.

Recommending Soil Copper Thresholds for Potato Production in Idaho
Provedor de dados: 18
Autores: Moore, Amber; Satterwhite , Megan; Ippolito, J.A.
A rising concern with the application of dairy wastes to agricultural fields is the accumulation of copper in the soil. Copper sulfate from cattle footbaths is washed out of dairy barns and into wastewater lagoons. Potato growers are concerned about this issue, as many of the predominant dairy producing areas in Southern Idaho are also in Idaho’s established potato production regions. The objective of this project was to evaluate potato growth and copper plant uptake for potatoes grown under low, moderate, and excessively high soil copper concentrations. This study was conducted in 2011 in a greenhouse setting at the USDA ARS Kimberly Research Station. To establish an effective copper response curve, 6 rates of copper sulfate (0, 100, 200, 300, 400, and...

Residual Effects of Fresh and Composted Dairy Manure Applications on Potato Production
Provedor de dados: 18
Autores: Moore D, Amber; Olsen L, Nora; Carey M, Anna; Leytem, A.B.
Potato growers in Idaho and other dairy producing regions often grow potatoes on fields that have had a history of fresh and composted manure applications. Growers remain uncertain of the impacts that previous manure applications will have on tuber yield and quality, as well as diseases, physiological disorders, and contamination by human pathogenic bacteria such as E. coli. The focus of this study was to determine the long term effects of manure, compost, and chemical phosphorus (P) fertilizer applications on tuber yields, tuber quality, nutrient uptake, tuber disorders and diseases, and soil nutrient concentrations. Russet Burbank potatoes were grown in 2008 and 2009 on plots that had received dairy manure, dairy compost, P fertilizer, or no P source...

Site-specific management of meloidogyne chitwoodi in Idaho potatoes using 1,3-dichloropropene; approach, experiences, and economics
Provedor de dados: 18
Autores: King, B.A.; Taberna, J.P, Jr.
Fumigation for nematode management in irrigated potato production systems of Idaho is widely practiced. Spatially uniform fumigation with large scale soil injection equipment is the only labeled application method for 1,3-dichloropropene. Plant-parasitic nematode species exhibit spatially variable population densities that provide an opportunity to practice site-specific fumigation to reduce chemical usage and production costs. During 2002-2008, 62 fields intended for commercial potato production in eastern Idaho were sampled using a geo-referenced grid sampling system for plant-parasitic nematode population densities. In total, 4,030 grid samples were collected representing nearly 3200 ha of commercial potato production. Collectively, 73% of the grid...

Evaluation of In-Row Plant Spacing and Planting Configuration for Three Irrigated Potato Cultivars
Provedor de dados: 18
Autores: Tarkalson, D.D.; King, B.A.; Bjorneberg, D.L.; Taberna, J.P.
Research studies have shown that planting potatoes (Solanum tuberosum L.) in a bed configuration can improve water movement into the potato root zone.  However, plant spacing recommendations are needed for potatoes planted in a bed configuration.  This study was conducted to evaluate the effect of in-row plant spacing and planting configuration on yield of Russet Burbank, Russet Norkotah, and Ranger Russet potatoes under sprinkler irrigation.  For the three varieties, the effect of in-row plant spacing (three spacing treatments) for each planting configuration (4 row conventional ridged-row [4RC], 5 row bed [5RB], and 7 row bed [7RB]), and the effect of planting configuration on total tuber yield, U.S. No. 1 tuber yield, percent No. 1 tubers, average size...

The ability to minimize potato yield and quality losses due to drought can be greatly improved by understanding the relative responses of different cultivars to seasonal variations in water supply. To address this need, we initiated a two year field experiment to determine the responses of the six potato cultivars to different seasonal drought patterns, including  1) full season irrigation at 100% ET, 2) irrigation at 100% ET terminated during late bulking , 3) full season irrigation at 70% ET , 4) irrigation at 70% ET terminated during late bulking , and 5) a gradual reduction in irrigation from 100% ET during tuber initiation through early bulking, to 70% ET during mid-bulking, and 50% ET through late bulking.

Site-Specific Nematode Management for Potatoes in Idaho Using 1,3-Dichloropropene; Experiences and Economics
Provedor de dados: 18
Autores: King, Bradley A.
Fumigation for nematode management in irrigated potato production systems of Idaho is widely practiced. Spatially uniform fumigation with large scale soil injection equipment is the only labeled application method for 1,3-dichloropropene. Plant-parasitic nematode species exhibit spatially variable population densities that provide an opportunity to practice site-specific fumigation to reduce chemical usage and production costs. From 2002 through 2008, 62 commercial potato fields in eastern Idaho were field tested using geo-referenced grid soil sampling for plant-parasitic nematode population densities. In total, 4,030 grid samples were collected representing nearly 3200 ha of commercial potato production. Collectively, 73% of the grid samples had Columbia...

Comparison of fall and spring bedding for furrow irrigated potatoes following fall moldboard or chisel plowing
Provedor de dados: 18
Autores: Shock, C.; Stieber, T.; Eldredge, E.; Sojka, R.; Kennedy-Ketcheson, E.
The decision to fall or spring bed potatoes is often dictated by weather and  processor contract agreements. Although there are advantages to both fall an(  spring bedding, soil conditions are often wet in the spring in Malheur County,  Oregon. Spring bedding of wet soils leads to soil compaction and decreased  water infiltration. The primary objective of the study was to determine the  effects of fall or spring bedding on tuber yields and quality under furrow  irrigation.  Determining the most effective method of fall potato ground preparation was  the second objective of the trial. Land for potato production is normally  moldboard plowed in the fall. Chisel plowing may provide better placement of  residues in bedded ground and thus promote higher...

Phosphorus nutrition of potatoes
Provedor de dados: 18
Autores: Tindall, Terry A.; Westermann, Dale T.; Stark, Jeffrey C.; Ojala, John C.; Kleinkopf, Gale E.
Phosphorus (P) is an essential nutrient required by  potatoes and all other plants. Potato plant roots readily  absorb P in the form of phosphate from the soil ( water)  solution. The absorbed phosphate moves upward  and downward in the plant. Phosphorus-deficient potato  plants transfer P from older tissues to actively growing,  younger tissues.  Symptoms of P deficiency include darker green, stunted,  spindly leaves with younger leaflets that turn upward  or curl. With prolonged deficiency, plants are  small and have reduced leaf area.

Genetic transmission of Solanum demissum (2n=6x=72) chromosomes from a pentaploid hybrid of S. tuberosum (2n=4x=48) into the aneuploid BC1 progeny
Provedor de dados: 19
Autores: Ono, Seijiro; Sanetomo, Rena; Hosaka, Kazuyoshi.
Solanum demissum is a homozygous, hexaploid wild species (2n = 6x = 72, AADDD(d)D(d)) that has long been used as a source of late blight resistance by repeated backcrossing with S. tuberosum (2n = 4x = 48, AAA(t)A(t)). To understand how S. demissum germplasm is incorporated to S. tuberosum through backcrosses, a linkage analysis of 590 DNA markers from S. demissum-specific simplex alleles was performed in an aneuploid population of 87 BC1 plants. Five hundred eighty-one markers were mapped to 38 linkage groups, of which 37 were assigned to potato chromosomes using markers of known location. Three homoeologous chromosomes were distinguished for each of the 12 potato chromosomes. Approximately 50 % of the markers were transmitted to the BC1 progeny except...

Autores: Kaganzi,   Elly; Ferris,   Shaun; Barham,   James; Abenakyo,   Annet; Sanginga,   Pascal; Njuki,   Jemimah M.
Uganda’s rapid urbanization, particularly in the capital city Kampala, offers new market opportunities for organized farmers to supply higher value produce for emerging growth markets such as multinational supermarket chains and fast food restaurants. Higher urban incomes allow consumers to shift from small shops and street food stalls to more formalized markets and modern food restaurants. These more formal market outlets provide both food safety and greater choice of produce. Supplying these outlets offers both higher income and improved business relations for farmers, but accessing these markets also requires significant upgrading in terms of product quality, more secure supply chains, and more efficient marketing and business management. To meet these...

Provedor de dados: 31
Autores: Sharma,   Gaurav; Singh,   S.P.
The study has examined the nature and extent of post-harvest losses in vegetable supply chain in the Kumaon division of Uttarakhand. Multistage cluster sampling has been used for selection of 80 vegetable growers, 40 farmers from the hilly region and 40 farmers from the bhabhar region. The sample has also included 25 market functionaries. Twelve major vegetables have been selected for the study. The maximum aggregate post-harvest losses have been found in tomato, followed by potato, brinjal, chilly, French bean and pea. The study has suggested that establishment of producer co-operatives to handle various activities relating to production and marketing of vegetables would help in reducing post-harvest losses.

Autores: Hafezi, Negar; Sheikhdavoodi, Mohammad Javad; Sajadiye, Seyed Majid.
The effect of drying behaviour on the drying rate and quality characteristics of potato slices in a vacuum-infrared drying system was studied. In this research, the effect of the infrared radiation powers (100, 150, and 200 W) and vacuum levels (20, 80, 140 mmHg and atmosphere pressure) at different slice thickness (1, 2 and 3 mm) on drying rate and shrinkage percentage and rehydration capacity were investigated.  It was concluded that infrared radiation power amount has a significant effect on processing time and drying rate. With increasing radiation power, drying time is reduced and consequently drying rate is increased. The drying rate curve of potato slices at initial drying time is in the ascending phase because of surface moisture evaporation and...

Autores: Pino,María Teresa; Ávila,Andrea; Molina,Andrea; Jeknic,Zoran; Chen,Tony H.H.
Cultivated potato crops are sensitive to drought stress, reducing yield and tuber quality when the soil water potential drops to -0.3 MPa. However, drought not only affects plant growth and physiological activity, but this stress also induces biochemical and molecular changes in the cellular gene expression profile. triggering genes that play a direct role in plant protection and gene regulation. The genes involved in regulation include C-repeat Binding Factors/Dehydration responsive element binding (CBF/DREB) transcription factors, which increase cold, drought and salt tolerance in different plant species. The aim of this research was to evaluate whether the overexpression of the ScCBF1 gene from Solanum commersonii enhances drought stress tolerance in...
