The PCR amplification and characterization of entire Pseudomonas syringae hrp/hrc clusters.

abstract：:Cloning the first avirulence (avr) gene has led not only to a deeper understanding of gene-for-gene interactions in plant disease, but also to fundamental insights into the suppression of basal defences against microbial attack. This article (focusing on Pseudomonas syringae) charts the development of ideas and resear...
