摘　　要：豆科植物是世界上重要的经济作物和饲料作物。近年来,我国对大豆、苜蓿等豆科植物的刚性需求快速增长。但是,豆科植物产量却增加缓慢。除了品种本身和种植模式等因素,外界的非生物胁迫和生物胁迫严重限制豆科作物的生产及产量提高。本文综述了豆科微管蛋白对干旱胁迫、重金属胁迫和光系统调节的响应,讨论了豆科微管如何参与病原菌入侵和Ca^(2+)信号调节,介绍了豆科植物大豆、菜豆和苜蓿中已经克隆解析的微管基因,以期为通过遗传改良豆科微管基因提高豆科植物耐胁迫能力提供理论指导。Legumes are important cash and fodder crops in the world.China′s rigid demands for crops,such as,soybean and alfalfa,have increased rapidly in recent years,but the legumes′yields have increased slowly.Besides legumes′variety and farming mode,their abiotic and biotic stresses seriously limit the production and yield.In this paper,we systematically summarized the response of legume tubulin to drought stress,heavy metal stress and light system regulation,discussed how legume tubulin participated in pathogen invasion and Ca^(2+)signal regulation,and introduced the cloned microtubule genes in Glycine max,Phaseolus vulgaris and Medicago truncatula;which would provide theoretical guidance for improving stress tolerance of legumes through genetic improvement of microtubule genes.
