construction of a single-gene deletion mutant, DELTAxehypBA1 and a triple-gene deletion mutant DELTAxehypBA1-BA2-AA. The mutants remain pathogenic, and mutations of the operon or the single genes XCV2724, XCV2728, and XCV2729 have no effect on nonhost resistance, either, indicating that these three enzymes are not involved in either pathogenicity or nonhost resistance reactions |
