摘要
植物通过转运蛋白吸收和转运矿质离子。为保持离子可用性和避免离子过度积累,离子转运蛋白的丰度和活性受到严格调控。铜转运蛋白(copper transporter,COPT)具有明显的结构特征和独特的亚细胞定位模式,在植物铜吸收、内源免疫和共生固氮等过程中发挥重要作用。该文对植物COPT家族蛋白的结构特征、生物学功能和调控机制等方面的研究进展进行综述,为植物铜稳态机制的揭示及品种改良提供参考。
Mineral ion absorption and transport depends on transporters in plants.To maintain ion availability and avoid excessive ion accumulation,the abundance and activity of ion transporters are tightly regulated.COPT(copper transporter)contains distinct structural characteristics and unique subcellular localization,and plays a key role in copper uptake,endogenous immunity and symbiotic nitrogen fixation in plants.In this review,the structural characteristics,biological function and regulatory mechanism of COPT protein were reviewed,providing a reference for revealing the mechanism of copper homeostasis and improving varieties in plants.
