摘　　要：山黧豆(Lathyrus sativus)是干旱、半干旱地区和贫困地区的重要饲料和粮食作物。长期以来,对于其内源毒素非蛋白氨基酸β-N-草酰-L-α,β-二氨基丙酸(β-N-oxalyl-L-α,β-diaminopropionicacid,β-ODAP)的过度强调导致山黧豆优良的农艺性状和在膳食平衡中的作用遭受无视。随着全球气候变化,山黧豆优良的综合抗逆性重新引起了科学家的正视。本文根据山黧豆作为传统有毒作物的定位,对其β-ODAP代谢与硫代谢以及抗旱性关系的研究进行了综述,并指出含硫营养的改善是山黧豆育种的重要方向。Lathyrus sativus is a very important food crop in arid,semi-arid,and poor areas.However,the excellent agronomic traits and dietary advantages of L.sativus were disregarded due to the overemphasis on its endogenous toxin,β-ODAP.With changes in global climate,this climate-resilient crop deserves more attention.Here,the current knowledge on the properties of L.sativus as a traditional toxic crop,the role of sulfur metabolism in L.sativus,and its contribution toβ-ODAP biosynthesis and drought resistance are reviewed.Moreover,strategies for the improvement of sulfur nutrition in L.sativus are evaluated.
