摘　　要：Plants have evolved a remarkable ability to sense and respond to changes in photoperiod,allowing adjustments to their growth and development based on seasonal and environmental cues.The floral transition is a pivotal stage in plant growth and development,signifying a shift from vegetative to reproductive growth.CONSTANS(CO),a central photoperiodic response factor conserved in various plants,mediates day-length signals to control the floral transition,although its mechanisms of action vary among plants with different day-length requirements.In addition,recent studies have uncovered roles for CO in organ development and stress responses.These pleiotropic roles in model plants and crops make CO a potentially fruitful target for molecular breeding aimed at modifying crop agronomic traits.This review systematically traces research on CO,from its discovery and functional studies to the exploration of its regulatory mechanisms and newly discovered functions,providing important insight into the roles of CO and laying a foundation for future research.
