The molecular dialogue between Arabidopsis thaliana and the necrotrophic fungus Botrytis cinerea leads to major changes in host carbon metabolism.

ABSTRACT: Photoassimilates play crucial roles during plant-pathogen interactions, as colonizing pathogens rely on the supply of sugars from hosts. The competition for sugar acquisition at the plant-pathogen interface involves different strategies from both partners which are critical for the outcome of the interaction. Here, we dissect individual mechanisms of sugar uptake during the interaction of Arabidopsis thaliana with the necrotrophic fungus Botrytis cinerea using millicell culture insert, that enables molecular communication without physical contact. We demonstrate that B. cinerea is able to actively absorb glucose and fructose with equal capacities. Challenged Arabidopsis cells compete for extracellular monosaccharides through transcriptional reprogramming of host sugar transporter genes and
