甘蓝类蔬菜是重要的蔬菜作物,主要包含结球甘蓝、花椰菜、青花菜、苤蓝、抱子甘蓝和芥兰等多个变种。在生产和制种过程中,该类蔬菜常发生未熟抽薹和亲本花期不遇等现象,利用分子设计育种改良甘蓝的耐抽薹性,可以有效地解决这些问题。然而甘蓝类蔬菜变种丰富,开花习性差异大,抽薹开花调控相关基因的研究相对分散。本文在简述了高等植物抽薹开花5种调控途径的基础上,归纳了诱导甘蓝类蔬菜抽薹开花所需的最适环境条件,总结了在春化途径、赤霉素途径和光周期途径中影响甘蓝类蔬菜抽薹开花的调控基因及其变异,构建了甘蓝类蔬菜的抽薹开花调控基因网络,并对甘蓝类蔬菜抽薹开花调控方面的后续研究提出了展望。本文为甘蓝类蔬菜耐抽薹性的改良提供参考。
Brassica oleracea vegetables, a group of leafy crops encompassing cabbage, cauliflower, broccoli, kohlrabi, brussels sprout, and kale, face persistent challenges in production and breeding, including premature bolting and asynchronous flowering between two parents. Improving bolting resistance by molecular design breeding strategies holds significant promise. However, the genetic complexity underlying flowering regulation in B. oleracea is compounded by the diverse flowering mechanisms across subspecies and fragmented knowledge of associated regulatory genes. This review concludes optimal environmental conditions for flowering of B. oleracea vegetables and summarizes genes and variants for flowering pathways which are mainly involved in gibberellin pathway, vernalization, and photoperiodic responses on the basis of five main flower regulation pathways in higher plants. The prospect of the follow-up research on the regulation of bolting and flowering of cabbage vegetables is also suggested. A conceptual gene interaction network that integrates key regulators of bolting and flowering of B. oleracea vegetables is proposed, providing a valuable reference for improving bolting resistance of B. oleracea vegetables.
