摘要
抗坏血酸(As A)在植物生长发育及果实品质形成方面扮演重要角色,对人体健康也具有重要作用。猕猴桃果实中富含As A,是研究植物As A代谢与调控的宝贵材料。目前对于As A生物合成已经有一定的了解,植物中公认的As A生物合成途径有4种,其中对主要合成途径L-半乳糖途径研究比较透彻,其他3条途径仍有未证实的酶反应和相关基因,As A代谢及调控机理也有待深入研究。综合国内外As A研究现状,主要从猕猴桃中As A积累的差异、As A的生物合成及其相关基因与调控酶进行阐述,以期为今后通过植物生物合成途径提高As A含量提供理论依据,为猕猴桃种质创新与品种改良奠定基础。
Ascorbic acid(AsA)plays an important role in plant growth and fruit quality formation,and also plays an important role in human health.Kiwifruit is rich in AsA,which is a valuable material for studying the metabolism and regulation of AsA in plants.Kiwifruit is rich in AsA,which is a valuable material to study the metabolism and regulation of AsA in plants.At present,there are four kinds of AsA biosynthesis pathways recognized in plants.Among them,L-galactose pathway has been studied thoroughly.The other three pathways still have undetermined enzyme reactions and related genes.The metabolism and regulation mechanism of AsA need to be further studied.In this paper,the difference of AsA accumulation in kiwifruit,the biosynthesis of AsA and its related genes and regulatory enzymes were reviewed.In order to provide a theoretical basis for the future improvement of AsA content through plant biosynthesis,kiwifruit germplasm innovation and variety improvement to lay the foundation.
