Root Colonization by Trichoderma atroviride Triggers Induced Systemic Resistance Primarily Independent of the Chitin-mediated Signaling Pathway in Arabidopsis.

ABSTRACT: Beneficial root endophytic fungi induce systemic responses, growth promotion, and induced systemic resistance (ISR) in colonized host plants. The soil application of chitin, a main component of fungal cell walls, also systemically induces disease resistance. Therefore, chitin recognition and its downstream signaling pathway mediate ISR triggered by beneficial fungi colonizing the root. The present study compared systemic disease resistance and transcriptional responses induced by Trichoderma, a representative beneficial root endophytic fungus, and chitin in Arabidopsis. Significant plant growth promotion was observed under root colonization by the three beneficial fungi tested: Trichoderma atroviride, Serendipita indica, and S. vermifera. Only T. atroviride and S. indica triggered ISR agai
