Biosynthesis of redox-active metabolites in response to iron deficiency in plants.

Nature chemical biology - 1 May 2018

Abstract excerpt

Iron is an essential but poorly bioavailable nutrient because of its low solubility, especially in alkaline soils. Here, we describe the discovery of a previously undescribed redox-active catecholic metabolite, termed sideretin, which derives from the coumarin fraxetin and is the primary molecule exuded by Arabidopsis thaliana roots in response to iron deficiency. We identified two enzymes that complete the...
