In response to Botrytis, the bacterized plantlets exhibited a stronger expression of PR genes (PR1, PR2, and PR5), and JAZ. Taken together, these data suggest that, in response to a subsequent infection by B. cinerea, B. phytofirmans PsJN potentiates the simultaneous induction of the SA- and JA- related genes. The gene discussed is ZNF346; the disease is infection.
