    摘要:

    MYB是植物体内数量较多的一类转录因子,在水稻中参与了多种生理生化过程,例如根系发育、细胞发育、次生细胞壁合成、分蘖形成、花器官发育、穗部形态建成、种子发育、激素代谢、次生代谢及生物胁迫和非生物响应等过程的调控。本文介绍了MYB转录因子家族的分类和蛋白结构,综述了水稻中MYB家族成员在生长发育、激素信号方面的最新研究进展,重点阐述了水稻中MYB成员在干旱、高温、低温、高盐、紫外线损伤等非生物胁迫过程中的调控作用,还探讨了MYB在真菌、病菌等生物胁迫中的防御作用。最后基于对水稻MYB转录因子的最新研究进展,总结了不足并提出了未来研究的展望。

    Abstract:

    MYB is one of the largest number of transcription factors in plants. MYB is involved in a variety of physiological and biochemical processes of rice, such as root development, cell development, secondary cell wall synthesis, tillering formation, flower organ development, spike morphogenesis, seed development, stimulatory metabolism, secondary metabolism, biological stress and abiotic response. This paper introduced the classification and protein structure of MYB transcription factor family, reviewed the latest research progress of MYB family members in growth and development, hormone signals in rice, described the regulatory role of MYB in abiotic stress processes of rice, such as drought, high temperature, low temperature, high salt, UV damage, etc., and also discussed the defense role of MYB in biological stress such as fungi, bacteria, etc. Finally, based on the latest research progress of rice MYB transcription factor, deficiencies were summarized and prospects for future research were put forward.
