Insights on suppression of bacterial leaf spot by Bacillus cyclic lipopeptides via induced resistance in Arabidopsis thaliana

We evaluated disease suppression by surfactin and iturin A against Pseudomonas syringae pv. maculicola MAFF 302783 in Arabidopsis thaliana and its mutants to gain insight into resistance pathways induced. Root treatments revealed that salicylic acid signaling via the isochorismate pathway was the ma...

Description
Summary:We evaluated disease suppression by surfactin and iturin A against Pseudomonas syringae pv. maculicola MAFF 302783 in Arabidopsis thaliana and its mutants to gain insight into resistance pathways induced. Root treatments revealed that salicylic acid signaling via the isochorismate pathway was the major signaling pathway elicited by both cyclic lipopeptides. Disease suppression was negated after treatment with higher levels of surfactin or iturin A, and this negation of disease suppression was not associated with an antagonistic effect by induction of jasmonate signaling pathway in host plants.
