Verticillium wilt is a widespread soil-borne vascular disease of crops. Hypovirulent strains pathogens show potential in providing cross-protection against wilt. To identify metabolites associated with the induction resistance, gas chromatography–mass spectrometry-based metabolomic technology was used to screen for differential induced by virulent (Verticillium dahlia V33) and hypovirulent (Gib...

Nicotiana otophora is a wild parental species of Nicotiana tabacum, an interspecific hybrid of Nicotiana tomentosiformis and Nicotiana sylvestris. However, N. otophora is least understood as an alternative paternal donor. Here, we compared the fully assembled chloroplast (cp) genome of N. otophora and with those of closely related species. The analysis showed a cp genome size of 156,073 bp and ...

Detailed analysis of the expression pattern of seven legumain genes from Nicotiana tabacum L. cv. SNN revealed that it showed neither coincidences with the branches of the phylogenetic tree of legumains nor with their conventional assignment to organs. This agreed well with the fact that, so far, no functional differences could be assigned to the sequence differences reflected in the branches o...

Infestation of potatoes with phythophthora infestans ,also known as ‘’potato late blight ‘’ is the most devastating potato disease world wide. Its occurrence often results in huge economic losses for producers. Current control measures involving extensive use fungicides come environmental costs. Efforts have been made to develop commercial varieties increased resistance p.infesting (the causal ...
