Abstract: 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.
