A virulence enhancement approach was used to clone a pathogenicity (prh) locus from a highly virulent pathogen by assaying the library in a second, less virulent strain that was compatible with the same host. A genomic library of the virulent Asiatic canker pathogen Xanthomonas citri was conjugally transferred to the opportunistic pathogen, X. campestris citrumelo, and the transconjugants were screened on Cirrus paradisi Duncan'(grapefruit) leaves (...)
