title: A gene from Xanthomonas campestris pv. vesicatoria that determines avirulence in tomato is related to avrBs3.
abstract: Strains of Xanthomonas campestris pv. vesicatoria that were avirulent in tomato leaves but virulent in pepper leaves were identified. A cloned gene, avrBsP, from one of the strains, Xv 87-7, converted a virulent strain in tomato to avirulent in tomato. A 1.7-kb subclone containing the avirulence gene cross-hybridized with the avirulence gene, which determines race 1 within the pepper group of strains (avrBs3). However, the two avirulence genes differ in their biological activity. The base sequences of the two avirulence genes were almost identical through the 1.7-kb segment of avrBsP, with significant differences only in some bases in the repeat region.
