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 re...

Quality traits such as flavour and texture are assuming a greater importance in crop breeding programmes. This study takes advantage of potato germplasm differentiated in tuber flavour and texture traits. A recently developed 44,000-element potato microarray was used to identify tuber gene expression profiles that correspond to differences in tuber flavour and texture as well as carotenoid cont...

The chem ical com position and m orphology of leaf surface waxes of Solanum tuberosum were analysed using FT -IR . G L C and MS studies. T here is a predom inance of sa tu rated and long chained com ponents resulting in a crystalline wax layer in the form of ribbons, n -alkanes are a m ajo r constituen t with C 3I being p rom inen t. Wax esters and 5-alcohols form the o th e r m ajor com ponent...

Paktylenchus tuberosus gen.n., sp.n. is described and illustrated from soil around Solanum tuberosum from Kaghan Valley, Pakistan. Paktylenchus gen.n, can be distinguished from the most closely related genus, Agelenchus Andrassy, 1954, by the distinct longitudinal striae, three incisures in the lateral field, and absence of males. Paktylenchus tuberosus shows affinities to Coslenchus Siddiqi, 1...

Root crop production in Papua New Guinea is reviewed. Crops considered are the major ones (Ipomoea batatas, Colocasia esculenta, Dioscorea aiata, D. escuienta, Xanthosoma sagitti!olium), other significant root crops (Manihot esculenta, Psophocarpus tetragonolobus, Cyrtosperma chpmissonis., Alocasia macro"htza and Solanum tuberosum) and 27 minor crops. For the major and significant crops, aspect...
