Summary Tomato varieties resistant to the bacterial wilt pathogen Ralstonia solanacearum have ability restrict movement in plant. Inducible vascular cell wall reinforcements seem play a key role confining R. into xylem vasculature of tomato. However, type compounds involved such physico‐chemical barriers remain understudied, while being component resistance. Here we use combination histological and live‐imaging techniques, together with spectroscopy gene expression analysis understand nature...
Bacterial wilt caused by Ralstonia solanacearum is one of the most destructive bacterial diseases for which no effective treatment exists. There an urgent need to understand basis resistance against this pathogen in order engineer efficient strategies field. We previously demonstrated that resistant tomato plants limit movement apoplast and xylem. As a first step dissect underlying mechanisms, we analysed proteome upon challenge with R. susceptible cultivar Marmande Hawaii 7996. Here,...
SUMMARY The intercellular space or apoplast constitutes the main interface in plant–pathogen interactions. Apoplastic subtilisin‐like proteases—subtilases—may play an important role defence and they have been identified as targets of pathogen‐secreted effector proteins. Here, we characterise Solanaceae‐specific P69 subtilase family interaction between tomato vascular bacterial wilt pathogen Ralstonia solanacearum . R. infection post‐translationally activated several P69s. Among them, P69D...
