| 摘 要： | 胚胎晚期丰富蛋白(LEA蛋白)是一种脱水保护剂,能够在干旱胁迫条件下保护生物大分子,尤其是膜结构的稳定性,减轻干旱造成的伤害.对其研究主要集中在植物胚胎学以及逆境生理学的领域.综述了有关第三组LEA蛋白及其基因的近年研究进展,这些基因的表达或蛋白累积与植物的渗透胁迫抗性呈正相关,第3组LEA基因可能具有的干旱保护功能已初步证实,同时分析了其广泛的应用前景.

| Abstract: | Late-embryogenesis-abundant protein(LEA protein)is a kind of protective agent of dehydration,which can protect biological macromolecules from the water-stress of environment,in particular,maintain the cell membrane stability,and mitigate harms from drought.Study of LEA proteins was one of the hot fields in plant embryology and stress physiology.The recent research progress of Group 3 LEA protein and gene research was summarized.It showed that these gene expressions or protein accumulation had positive correlation with the botanical osmotic pressure,and it was confirmed that Group 3 LEA gene might resist droughts.Prospects of wide application were also analyzed. |
