总之，该研究揭示了bHLH转录因子（PFA和PFB蛋白）通过形成正反馈回路调控XPP细胞特征的作用机制，从而在侧根原基形成中发挥作用。 碱性螺旋-环-螺旋 (basic helix-loop-helix,bHLH)蛋白属于转录因子超家族,在真核生物中广泛分布.目前,大部分bHLH转录因子功能在动物中已明确,但在植物中的研究相对滞后.bHLH转录因子作为植物体内第二大类转录因子,其在植物的生长发育,生理代谢及逆境应答等过程中起. This provides the basis for the functional annotation of the bhlh family in land plants and the systematic examination of a wide range of functions regulated by this transcription factor family.

近期，日本Osaka University Tatsuo Kakimoto 研究组在 Nature Plants 发表了题为 Two types of bHLH transcription factor determine the competence of the pericycle for lateral root initiation 的研究论文，揭示了两类bHLH转录因子介导中柱鞘细胞形成侧根原基的机制。
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.
