Phoma medicaginis stimulates the induction of the octadecanoid and phenylpropanoid pathways in Medicago truncatula.

ABSTRACT: Gene expression changes and metabolite abundances were measured during the interaction of Medicago truncatula with the fungal necrotrophic pathogen Phoma medicaginis in leaf tissue of susceptible and resistant accessions. Over 330 genes were differentially expressed in plants infected with P. medicaginis relative to mock-inoculated plants at 12 h post-inoculation. Of these, 191 were induced in either the resistant or the susceptible accession, with 143 genes repressed. Expression changes were observed in genes involved in the oxidative burst, cell wall strengthening and lipid metabolism, as well as several transcription factors. Genes related to salicylic acid, jasmonate and ethylene responses were up-regulated, as well as genes leading to the production of jasmonic acid. Significant induc
