Reduced susceptibility of tomato stem to the necrotrophic fungus<i>Botrytis cinerea</i>is associated with a specific adjustment of fructose content in the host sugar pool

Abstract

Small variations of fructose content among the sugar pool are unlikely to affect intrinsic pathogen growth. Our results highlight distinct use of host glucose and fructose after infection by B. cinerea and suggest strongly that adjustment of the relative fructose content is required for enhanced plant defence.
