Specific recognition of Pseudomonas syringae strains that express the avirulence gene avrPphB requires two genes in Arabidopsis, RPS5 and PBS1. Previous work has shown that RPS5 encodes a member of the nucleotide binding site-leucine rich repeat class of plant disease resistance genes. Here we report that PBS1 encodes a putative serine-threonine kinase. Southern blot analysis revealed that the pbs1-1 allele contained a deletion of the 3' end of the PBS1 open reading frame. DNA sequence analysis… CONTINUE READING

DNA sequence analysis of the pbs1 - 2 allele showed it to be a missense mutation that caused a glycine to arginine substitution in the activation segment of PBS1 , a region known to regulate substrate binding and catalytic activity in many protein kinases .
