摘  要:
磷是高等植物生长发育所必需的大量元素之一,现有的研究表明植物磷酸盐转运蛋白介导了植物体内磷的吸收及转运。在低磷胁迫下,植物主要利用高亲和力磷吸收系统通过表皮细胞质膜从根围吸收磷元素。目前绝大部分克隆出来的磷酸盐转运蛋白基因都属于高亲和力的Pht1家族。概述了近年来水稻磷酸盐转运蛋白Pht1家族基因的表达调控机理和生物学特征,并对进一步研究做了展望。

摘  要:
Phosphorus(Pi)is one of the major nutrients for higher plant growth and development;recently studies show that plant phosphate transporters(PTs)mediate the uptake and translocation of this nutrient within plants.Under conditions of Pi starvation,the major mechanism for Pi uptake by roots is usually considered to be the high affinity system.And the majority of the plants PTs belong to the Pht1 family.In this paper,the research progresses of rice phosphate transporters Pht1 on expression regulation and biological properties in last decade were reviewed.
