脯氨酸在植物非生物胁迫耐性形成中的作用

植物作为固着生活的有机体,经常暴露在多变且对其生长发育不利的环境条件中,这些生物或非生物的胁迫因子严重影响着植物的生长、发育、生存和分布。脯氨酸在植物抵抗逆境胁迫过程中起着重要的作用。根据国内外的最新研究进展,结合我们的研究成果,对植物体内脯氨酸的代谢途径、渗透调节、抗氧化、分子伴侣、生长发育信号和毒性等方面进行了综述,并对该研究领域作了展望。

The Roles of Proline in the Formation of Plant Tolerance to Abiotic Stress

Plants as sessile organisms are constantly exposed to variable and often unfavorable environmental condition,the growth,development,survival,and distribution of plants are greatly affected by various abiotic and biotic stress factors.Proline plays major roles in the formation of plant resistance to environmental stress.Basing on the recent advance in this field,the metabolic pathway,osmotic adjustment,antioxidant,molecular chaperone,growth and development signal,and toxicity of proline were reviewed here,th...
