摘要: 雄性不育广泛存在于种子植物中。植物雄性不育不仅是植物生殖发育研究的重要内容,同时也可作为杂种优势利用的有效工具,因而具有重要的理论和应用价值。bHLH转录因子家族是植物中成员最多的转录因子家族,在植株的整个生长发育过程中起着重要的调控作用。本文介绍了拟南芥、水稻、玉米等几种重要模式植物bHLH转录因子调控雄蕊发育的作用机制,并重点阐述其功能异常引起细胞核雄性不育的分子机制,以期为作物育种与理论研究提供参考。

Abstract: Male sterility exists widely in the spermatophytes. It contributes to the study of plant reproductive development and can be used as an effective tool for hybrid seed production in heterosis utilization. Therefore, the study on male sterility is of great value in both theory and application. As one of the largest transcription factor families in plants, basic helix-loop-helix proteins (bHLHs) play a crucial role in regulating plant growth and development. This paper introduces the mechanism of bHLH regulating stamen development in several important model plants. Furthermore, we discuss the molecular mechanisms of genic male sterility resulting from bHLH dysfunction to provide references for crop breeding and theoretical studies.

Key words: male sterility, bHLH transcription factor, programmed cell death, transcriptome sequencing
