开花生热是某些植物科属在长期进化过程中形成的一项重要适应机制,有助于植物花器官抵御低温伤害,并且能够促进昆虫访花和传粉受精,对于确保植物的生殖成功具有重要的生物学意义.本文基于国内外近年来植物开花生热研究方面取得的重要进展,结合开花生热活体实时检测的技术发展,对植物开花生热的类型、生物学功能以及调控机制进行综述,并展望了植物开花生热研究领域亟待解决的重要问题.
Floral thermogenesis, which has been developed during the long history of evolution, is an adaptive strategy of some plants. It is of crucial significance for ensuring reproduction success of thermogenic plants, since it avoids cold damage to flowers and plays a critical role in attracting pollinators and promoting pollination. Based on recent research progress on thermogenesis at home and abroad, we summarized patterns, biological functions, and underlying regulatory mechanisms of floral thermogenesis, by referring to emerging techniques of real time and in vivo investigation into floral thermogenesis. Finally, we concluded by highlighting several outstanding biological questions that need to be addressed for further advance understanding in this research field.
