| 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... |

| 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’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,... |

| ABSTRACT In the biennium 2013-14, the world produced 1,134.27 million tons of vegetables annually. The production of garlic, onion, potato, tomato and watermelon accounted for 66.5% of the total. Brazil, in 2012, considering 40 vegetables, produced around 23 million tons, in 900.0 thousand hectares. Potatoes, tomatoes (table and processing), onions, watermelons, carrots, sweet potatoes, lettuce and cabbage, the main vegetables in Brazil, accounted for 64.0% of the total. This work presents the evolution of production, commercialization, and availability of garlic, onions, potatoes, tomatoes and watermelons in Brazil and in the world. In Brazil, the work focused on two distinct periods: 1970-1990 {when the Support Program for Production and... |

| 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... |
