富含叶酸水稻研究进展

叶酸缺乏是世界性的公共健康问题,严重影响人类健康。水稻是世界第一大主粮,也是我国大部分人日常能量摄入的主要来源。但是水稻籽粒中叶酸含量极低,因此,通过提高水稻的叶酸含量将有助于解决我国以及全球许多以水稻为主粮的国家和地区的叶酸缺乏问题。本文介绍了叶酸的结构、在生物中的生理功能及叶酸缺乏带来的影响,阐述了叶酸在植物体内生物合成的途径,以及目前水稻叶酸强化的研究进展。

Progress on High Folate Content Rice

Folates deficiency is a global public health problem, has profound effects on human health. Rice is the most important sta-ple crops in the world, and provides most population energy intake in China. Since rice seeds contain very little folates, enhancing fo-lates content in rice would be a cost-effective way to solve folates deficiency in China and some countries and regions where the sta-ple crop is rice. This review introduced the structure and physiological functions of folates, and the influences of folates deficiency. The biosynthetic pathway in plant and progress in folates-biofortification rice were also reported.
