Characterization of a variant of Xanthomonas citri subsp. citri that triggers a host-specific defense response.

abstract：:The induction of plant defense mechanisms by resistance inducers is an attractive and innovative alternative to reduce the use of fungicides on wheat against Zymoseptoria tritici, the responsible agent of Septoria tritici blotch (STB). Under controlled conditions, we investigated the resistance induction in three whea...
