摘　　要：SCARECROW-LIKE (SCL)蛋白是GRAS转录因子家族的重要成员,可以调控下游基因,对植物根、茎、叶、种子的生长发育以及外界信号的响应具有重要的调控作用。本研究介绍了SCL蛋白对植物中皮层的生长发育、不定根和腋生分生组织的形成、叶绿素合成的影响,SCL蛋白在赤霉素信号、光信号、胁迫信号中的作用以及SCL蛋白参与miRNA表达调控等。通过研究结果以期增加人们对SCL家族的进一步了解,为该类蛋白在植物生长发育、抗病抗逆等方面的研究与应用提供参考。The SCARECROW-LIKE(SCL)proteins belong to GRAS transcription factor family.SCL proteins re-gulate expression of their downstream genes,plant growth and development of plant roots,stems,leaves,and seeds,as well as the responses to enviromental signals.Here,we introduce the functions of SCL protein on the growth and development of plant endothelium,the formation of adventitious roots and axillary meristems,the synthesis of chlorophyll,the roles of SCL protein on gibberellin signal,light signal,stress signal and participation in miRNA gene regulation.According to this review,it will help people further understand the SCL family,and provide refer-ences for the application of SCL proteins in plant growth and development,disease resistance and stress resistance.
