Advances in Iron Deficiency-induced Coumarin Biosynthesis and Their Functions in Iron Absorption in Plants
摘要
Abstract
Coumarins are a class of phenolic compounds with benzopyrones as the parent ring structure,categorized into simple and complex coumarins,and widely distributed in higher plants.In recent years,studies have shown that root-secreted coumarins can promote iron absorption in plants.Here,the recent progress in the discovery and identifica-tion of genes related to the biosynthesis and regulation of plant iron deficiency-induced coumarins is reviewed,and the molecular mechanisms of the biosynthesis,storage,secretion,and regulation of iron deficiency-induced coumarins are further elaborated.The mechanism by which coumarins could promote plant iron uptake has also been discussed.Finally,this paper provides a preliminary outlook on the future research directions to gain knowledge of these mechanisms,which could offer novel opportunities to generate iron deficiency-tolerant crops and iron-biofortified crops.关键词
