| Abstract: | Modern molecular biological techniques have provided effective means for the study of the mechanisms of bacterial pathogenicity for plants. Recently, the extracellular proteases produced by Xanthomonas campestris pv. campestris have been demonstrated at molecular level to be important in pathogenicity. This review describes the recent progress in the studies of the extracellular proteases, the cloning and analysis of the genes encoding the enzymes, the construction of protease negative mutants and the role of the enzymes in pathogenicity of X. c. pv. campestris. |
