摘　　要：干旱、盐碱和冻害是限制植物生长发育的主要逆境因子,胚胎晚期丰富蛋白(LEA)是一类重要的植物细胞脱水保护蛋白,在抵御干旱等非生物胁迫过程中发挥着重要功能。介绍了植物LEA蛋白的种类、结构及其表达特性,并综述了该类蛋白在提高植物抗旱、耐盐及抗冻能力等方面的研究进展。Drought, salinity and cold stresses are major adverse environmental factors which greatly limited the growth and development of plants, the late embryogenesis abundant proteins （LEA）are a kind of important cellular dehydration protectants and were assumed to play crucial roles during the periods of defending to drought and other abiotic stresses. The classification, construction and expression characteristics of LEA proteins were summarized and the functional researching progresses of LEA proteins for improving the drought, salinity and cold stress tolerance in plants were also reviewed.
