摘要:

神经酸是一种超长链单不饱和脂肪酸,最初发现于哺乳动物神经组织中,是脑部神经组织和神经细胞的天然核心成分,具有修复受损神经纤维、帮助神经细胞再生的功能。神经酸的来源由动物到植物的转变极大地促进了神经酸的研究。近年来,国内外科学家尝试通过转基因技术进行高神经酸植物的遗传改良。含神经酸的油菜在神经酸植物来源中脱颖而出,有望解决神经酸短缺的现状。综述了植物中神经酸的生理功能和来源,介绍了植物中神经酸的生物合成途径和从植物中提取神经酸的工艺,以期为植物神经酸相关研究和油菜创新育种提供理论参考。

关键词: 神经酸, 生理功能, 合成途径, 遗传改良

Abstract:

Nervonic acid is a kind of very-long chain monounsaturated fatty acid which was found in mammalian nerve tissue first. Nervonic acid is the core natural component of brain nerve tissue and nerve cells, with the function of repairing damaged nerve fibers and helping nerve cell regeneration. The transition of neuroic acid sources from animal to plant has greatly promoted the study of neuroic acid. In recent years, scientists at home and abroad have tried to genetically improve the content of nervonic acid in plants by transgenic technology. Rapeseed containing nervonic acid stands out among the plant sources of nervonic acid, which is expected to solve the shortage of nervonic acid. The physiological functions and sources of neuroic acid in plants were reviewed, and the biosynthetic pathway and extraction technology of neuroic acid from plants were introduced, which was expected to provide theoretical reference for the research on neuroic acid and rapeseed innovative breeding.

Key words: nervonic acid, physiological function, synthetic pathway, genetic improvement
