摘要：

在外界干旱、低温、盐等逆境胁迫的情况下，某些植物能自身合成甜菜碱有效减轻植物受到的伤害。对于自身不能合成甜菜碱的植物，可以通过基因工程法或外源施入法促进体内甜菜碱的积累，从而达到同样的缓解伤害效应。笔者概述了甜菜碱的发现、生物合成途径、在植物中的应用研究进展，同时对甜菜碱在烟草作物上的研究现状、存在问题和应用前景进行了可行性评价分析，认为甜菜碱具有成本低、用量少、抗逆性强等特点，在烟草种植中已经具备了推广应用的潜力。

Abstract:

Some plants could accumulate glycine betaine by self synthesis so as to alleviate the injury caused by drought, low temperature and salt stress. Meanwhile it could promote the accumulation amount of glycine betaine by genetic engineering or exogenous application for plants which could not make by themselves. This article summarized main research progress on discovery, biosynthetic pathway and applications of glycine betaine in plants, meanwhile evaluated research status, existing problems and application prospect of glycine betaine in tobacco. At last, we concluded that glycine betaine had the popularization and application potential in paddy yield of tobacco for its low cost, little dosage and strong stress resistence.
