ATML1-GIR1-TPL/TPR transcriptional repression module controls glucosinolates and giant cells in Arabidopsis thaliana sepals
Glucosinolates (GSLs) are sulfur- and nitrogen-containing secondary metabolites that serve as defense compounds in Arabidopsis and other members of the Brassicales. Although the enzymatic pathway that produces GSLs is well-studied, the upstream mechanisms that control their tissue-specific synthesis are poorly understood. We identified a novel repression module that transcriptionally regulates GSL levels in sepals, the modified leaves that protect reproductive tissues within the floral bud.
Elevated temperature drives the biosynthesis of novel acylated glucosinolates in Arabidopsis thaliana seeds
Glucosinolates (GSLs) are major defensive compounds massively accumulated in Brassicaceae seeds, including that of the model plant Arabidopsis thaliana. While most studies have focused on the role of GSL in responses to biotic stress, the potential regulation and function of GSLs in responses to abiotic stresses have been neglected, particularly in seeds. In this study, multi-omic analyses revealed a previously uncharacterized GSL modification pathway induced by elevated temperature (ET)...
A co-proteomic view of metabolite-specific interactions in the Botrytis cinerea-Arabidopsis pathosystem
To successfully infect their myriad hosts, generalist plant pathogens must tolerate a vast arsenal of plant specialized defense metabolites. To understand how host-specific metabolites influence plant-generalist pathogen interactions, we conducted a co-proteomic analysis of both Arabidopsis thaliana and Botrytis cinerea proteomes from the same samples during early infection. The Arabidopsis proteomic responses to Botrytis center around induction and suppression of defense metabolite...
