Abstract

Cloned DNA from race 4 of Pseudomonas syringae pv: phaseolicola has been shown to confer avirulence on P. syringae pv. pisi toward pea. The library cosmid, pPPY40 has been shown by transposon mutagenesis and sub-cloning to carry two regions of DNA, both of which are required for expression of the avirulence phenotype. The aims of this proposal are to (1) characterize the 2 regions of insert DNA responsible for the avirulence phenotype; (2) determine the number of genes involved and their relationship to one another; (3) investigate the regulation of the genes involved; (4) overexpress the avirulence proteins and search for elicitor of the HR. This will involve further transposon mutagenesis and sub-cloning; DNA sequence analysis, the use of reporter gene systems, to study control and overexpression to seek elicitor activity in planta.
