Current studies have shown that the secretory cavity of citrus plants occurs in schizolysogenesis, and the development of secretory cells is a process of programmed cell death. However, the study of the development of secretory cavity has experienced a hundred years. This review focuses on the origin, development and programmed cell death of secretory cavity in Citrus, in order to provide a reference for future studies on secretory cavity morphogenesis. %K Citrus %K Secretory cavity %K Schizolysigenous %K PCD %K Development %U https://xuebao.scau.edu.cn/zr/html/2022/6/20220612.htm
