WebAug 29, 2003 · PBS1 was cleaved in tobacco in the presence of wild-type AvrPphB, but not AvrPphB (C98S) ( Fig. 1B ). Previously, we identified a mutant PBS1 allele, pbs1-2, that blocks AvrPphB-induced resistance in Arabidopsis ( 14 ). Because the protein encoded by this allele, PBS1 (G252R) ( 16 ), lacks kinase activity, we asked whether PBS1 kinase …
