Individual leaves of potato (Solanum tuberosum L. W729R), a C(3) plant, were subjected to various irradiances (400-700 nm), CO(2) levels, and temperatures in a controlled-environment chamber. As irradiance increased, stomatal and mesophyll resistance exerted a strong and some-what paralleled regulation of photosynthesis as both showed a similar decrease reaching a minimum at about 85 neinsteins...

The major cultivated potato, Solanum tuberosum, and six other related cultivated species, are hypothesized to have arisen from a group of weedy relatives indigenous to the central Andes of central Peru, Bolivia, and northern Argentina. A major problem hindering investigations of the origins of the cultivated species has been a continuing debate over the species boundaries of their putative prog...

Glutathione S-transferases (GST) form a large family of non-photosynthetic enzymes known to function in detoxification of xenobiotics. We have cloned and characterized a novel, low temperature regulated GST, Solanum commersonii glutathione S-transferase (Scgst1), from a cold acclimated wild potato species S. commersonii and studied the level of its transcription in freezing tolerant and sensiti...

background: p. atrosepticum is a commercially important pathogen. it causes blackleg in the field and soft rot of tubers after the harvest. this effect is due to secretion of depolymerases and other virulence factors by several mechanisms including t3ss objectives: the effect of bacterial t3ss on solanum tuberosum (s. tuberosum) varieties and its relationship with s. tuberosum resistance gene e...

Dickeya zeae is an emerging rice (Oryza sativa) pathogen causing bacterial foot rot. Related pathogens affect maize (Zea mays) and potato (Solanum tuberosum) and a variety of important ornamental and floral plants. Here, we present the draft genome sequence of D. zeae DZ2Q, an isolate obtained from rice grown in Italy.

Pectobacterium atrosepticum strain CFBP6276 is a pectinolytic enterobacterium causing blackleg and soft rot of the stem and tuber of Solanum tuberosum. Its virulence is under the control of quorum sensing, with N-acylhomoserine lactones as communication signals. Here, we report the genome sequence of P. atrosepticum strain CFBP6276.

This work investigated the effects of soft rot (Erwinia carotovora) on respiration rate of potatoes stored at three storage temperatures (5, 10, and 15 C) covering temperature ranges commonly encountered in storage. Five treatments were evaluated: healthy (H), healthy with holes (HW), inoculation with no incubation (I0), inoculation with 24 hr incubation (I1), and inoculated with 48 hr incubati...

Three consecutive years of field experiments were carried out to investigate the effect of root temperatures induced by the application of mulches for phytoextraction of As, Ag, Cr and Sb using potato plants (roots, tubers, stems and leaflets). Four different plastic covers were used (T1: transparent polyethylene; T2: white polyethylene; T3: white and black coextruded polyethylene; and T4: blac...
