摘　　要：高等植物叶绿体中的基粒是由多个圆盘状类囊体堆叠在一起形成的特殊结构,它的形成可以将光合蛋白复合体分配在类囊体膜的不同位置,使类囊体膜具有横向异质性,能有效进行光合作用。促进基粒形成的关键是使类囊体膜弯曲,目前发现导致膜弯曲的关键因子是CURT1蛋白。该文对近年在拟南芥(Arabidopsis thaliana)和蓝藻(Cyanobacteria)中有关CURT1蛋白的研究进展进行综述,并对未来类囊体膜结构与功能的动态调控研究进行展望。The grana in chloroplast of higher plants is a structure composed of many thylakoid discs stacked together. The formation of the grana facilitates the distribution of the photosynthetic protein complex in different positions in thylakoids, that is, it has lateral heterogeneity and can effectively carry out photosynthesis. The key step to promote the formation of grana is to bend the thylakoid membrane. CURVATURE THYLAKOID 1(CURT1) protein has been found to be the key factor leading to membrane bending. In this review, the recent research progresses of CURT1 protein in Arabidopsis thaliana and Cyanobacteria were summarized, and the prospect of CURT1 protein research in the future was put forward.
