植物SPL转录因子研究进展

Research Progress of SPL Transcription Factors in Plants

SPL(squamosa promoter-binding protein-like)基因编码的绿色植物所特有的转录因子,参与植物形态建成、花发育、根发育等过程,调控植物不同发育时期的转变,维持植物育性,响应植物的外界胁迫,在植物的整个生长发育过程中发挥着重要的作用。对SPL转录因子的研究概况、结构特征、同源基因克隆情况、表达调控模式以及生物学功能进行了综述,以期为进一步进行SPL转录因子的相关研究奠定基础。

SPL(squamosa promoter-binding protein-like)gene encodes a transcription factor unique to green plants,which participates in plant morphogenesis and flower development,root development and other processes,regulates the transformation of plants at different developmental stages,maintains plant fertility,responds to external stresses of plants,and plays an important role in the whole process of plant growth and development.The research situation,structural characteristics,homologous gene cloning,expression regulation pattern and biological functions of SPL transcription factors were reviewed in this paper,in order to lay the foundation for further research on SPL transcription factors.
