Abstrakt: The soilborne fungi Sclerotinia sclerotiorum and Rhizoctonia solani are among the most devastating pathogens for lettuce production. This study aimed to evaluate the efficacy of an Arthrobacter and Blastobotrys strain, named FP15 and FP12, respectively, against S. sclerotiorum and R. solani in lettuce. The incorporation of strains FP12 and FP15 in the transplant substrate plug of lettuce resulted in reduced S. sclerotiorum and R. solani caused symptoms. Transcriptomic analysis performed on the pathogenesis related (PR) gene PR1, LIPOXYGENASE (LOX) and ETHYLENE RESPONSE FACTOR 1 (ERF1), marker genes of the salicylic acid (SA), jasmonate (JA) and ethylene (ET) dependent defences, respectively, suggested the early triggering of the SA, ET and JA dependent defences and the constitutive triggering of the JA and JA/ET dependent defences by FP12 and FP15, respectively, upon R. solani and S. sclerotiorum infection.
