Modulating plant primary amino acid metabolism as a necrotrophic virulence strategy: the immune-regulatory role of asparagine synthetase in Botrytis cinerea-tomato interaction.

ABSTRACT: The fungal plant pathogen Botrytis cinerea is the causal agent of the "gray mold" disease on a broad range of hosts. As an archetypal necrotroph, B. cinerea has evolved multiple virulence strategies for inducing cell death in its host. Moreover, progress of B. cinerea colonization is commonly associated with induction of senescence in the host tissue, even in non-invaded regions. In a recent study, we showed that abscisic acid deficiency in the sitiens tomato mutant culminates in an anti-senescence defense mechanism which effectively contributes to resistance against B. cinerea infection. Conversely, in susceptible wild-type tomato a strong induction of senescence could be observed following B. cinerea infection. Building upon this earlier work, we here discuss the immune-regulatory role o
