    摘要:

    MYB是植物体内数量较多的一类转录因子,其家族成员在水稻全生育期各个阶段和多种逆境胁迫中发挥重要的调控作用,例如参与根系发育、细胞发育、次生细胞壁合成、分蘖的发生和伸长、花器官分化和发育、穗部形态建成、种子发育、各种激素代谢、次生代谢物的合成与代谢及生物和非生物胁迫响应等过程的调控。本综述介绍了MYB转录因子家族的分类和不同亚群的蛋白结构,总结了MYB家族成员在水稻地下部和地上部的生长发育、激素信号方面的最新研究进展,重点阐述了MYB家族成员对水稻在干旱、高温、低温、高盐、紫外线损伤等非生物胁迫条件下的调控作用,并探讨了MYB基因对水稻在真菌、病菌等生物胁迫中起到的防御作用。最后纵观对水稻MYB转录因子的最新研究进展,总结了三点不足,同时就未来对于MYB转录因子的研究提出了三个方向上的展望。

    Abstract:

    MYB is one of the more abundant classes of transcription factors in plants. Its family members play important regulatory roles in all stages of rice reproduction and in a wide range of adversity stresses. For example, it is involved in the regulation of processes such as root development, cell development, secondary cell wall synthesis, tiller development and elongation, floral organ differentiation and development, spike morphogenesis, seed development, the metabolism of various hormones, the synthesis and metabolism of secondary metabolites and biotic and abiotic stress responses. This review describes the classification of the MYB transcription factor family and the protein structures of the different subgroups, and summarizes the recent research progress of MYB family members in growth and development and hormone signalling in the subsurface and aboveground parts of rice. The regulatory roles of MYB family members on rice under abiotic stress conditions such as drought, high temperature, low temperature, high salt and UV damage were highlighted, and the defence role played by MYB genes against biotic stresses such as fungi and pathogens was explored. Finally, throughout the recent progress of research on the MYB transcription factor in rice,we summarized three shortcomings of the latest research progress on MYB transcription factors in rice and proposed three directions for future research on MYB transcription factors.
