Premature bolting in radish (Raphanus sativus L.) is a major obstacle in spring radish production, severely reducing the commercial quality and economic value of the fleshy root. This paper systematically reviews the developmental process of radish bolting, molecular and genetic regulatory mechanisms, physiological and biochemical basis, and environmental interaction effects. It focuses on the structure and function of the FLC gene family (a key repressor in the vernalization pathway), the epigenetic regulatory mechanisms, and the key regulatory gene RsMIPS3 identified based on T2T genome analysis. In addition, the paper summarizes the research progress in screening for bolting tolerant germplasm, marker assisted selection breeding, and gene editing technologies, and introduces representative bolting tolerant varieties developed in recent years. The challenges currently facing research and future development directions are also discussed, aiming to provide a theoretical reference for the genetic improvement and production application of bolting traits in radish. |
