Anther development is a complex process essential for plant reproduction and crop yields. In recent years, significant progress has been made in the identification and characterization of the bHLH transcription factor family involved in anther regulation in rice and Arabidopsis, two extensively studied model plants. Research on bHLH transcription factors has unveiled their crucial function in controlling tapetum development, pollen wall formation, and other anther-specific processes. By exploring deeper into regulatory mechanisms governing anther development and bHLH transcription factors, we can gain important insights into plant reproduction, thereby accelerating crop yield improvement and the development of new plant breeding strategies. This review provides an overview of the current knowledge on anther development in rice and Arabidopsis, emphasizing the critical roles played by bHLH transcription factors in this process. Recent advances in gene expression analysis and functional studies are highlighted, as they have significantly enhanced our understanding of the regulatory networks involved in anther development.
花药发育是植物繁殖和作物产量所必需的复杂过程。近年来,在水稻和拟南芥这两种广泛研究的模式植物中,参与花药调控的bHLH转录因子家族的鉴定和表征取得了重大进展。对bHLH转录因子的研究揭示了它们在控制绒毡层发育、花粉壁形成和其他花药特异性过程中的关键作用。通过深入探索花药发育和bHLH转录因子的调控机制,我们可以深入了解植物繁殖,从而加速作物产量的提高和新植物育种策略的开发。本综述概述了目前关于水稻和拟南芥花药发育的知识,强调了bHLH转录因子在此过程中所起的关键作用。突出了基因表达分析和功能研究的最新进展,因为它们显著增强了我们对花药发育相关调控网络的理解。
