钾离子转运载体HAK/KUP/KT家族参与植物耐盐性的研究进展
|
摘要
钾可以通过多种方式参与植物的生长和发育,在植物缓解盐等非生物胁迫方面发挥重要作用。在植物中,HAK/KUP/KT是成员数目最多的一类高亲和钾转运蛋白家族,本文对该家族成员的分类、盐胁迫下钾的吸收、转运、生理功能和分子调控机制等方面的研究进行了综述,并对该转运体家族今后的研究方向进行了展望。
Potassium is involved in plant growth and development in a variety of ways and also plays an important role in mitigating salt stress.HAK/KUP/KT is the largest family of potassium transporters in plants.We summarized its roles in potassium absorption,transportation,physiological function,and molecular mechanisms in response to salinity stress.Future development of the HAK/KUP/KT family is discussed.
