Plant nitrogen supply affects the Botrytis cinerea infection process and modulates known and novel virulence factors.

ABSTRACT: Plant nitrogen (N) fertilization is known to affect disease; however, the underlying mechanisms remain mostly unknown. We investigated the impact of N supply on the Arabidopsis thaliana-Botrytis cinerea interaction. A. thaliana plants grown in low nitrate were more tolerant to all wild-type B. cinerea strains tested. We determined leaf nitrate concentrations and showed that they had a limited impact on B. cinerea growth in vitro. For the first time, we performed a dual RNA-Seq of infected leaves of plants grown with different nitrate concentrations. Transcriptome analysis showed that plant and fungal transcriptomes were marginally affected by plant nitrate supply. Indeed, only a limited set of plant (182) and fungal (22) genes displayed expression profiles altered by nitrate supply. The ex
