Abstract

Preliminary work has provided good evidence for a positive determinant of virulence (vir), which is located on a 150 kb native plasmid in Pseudomonas syringae pv. phaseolicola. We aim to characterise the vir gene or genes we have cloned and determine their function. We will identify the genes responsible for eliciting the hypersensitive reaction (HR) of the bean host by bacteria that are cured of the 150 kb plasmid. We shall search for vir homologues among other P. syringae pathovars. A model, which envisages three alternative sites of vir gene(s) function, will form a basis for investigation of function, both in planta and in the bacterium.
