摘 要:植物MADS-box转录因子是一类含有MADS-box结构域的蛋白,在调控植物生长发育和逆境响应中发挥重要作用。水稻MADS-box转录因子的生物学功能广受关注,取得了诸多研究进展,在已知的75个水稻MADS-box家族成员中至少有33个成员的功能已被研究报道,它们在花器官发育、穗发育、开花习性、种子发育、株高形态建成、根系发育,以及干旱、盐分、高温、低温、稻瘟病等生物与非生物胁迫响应等方面扮演了重要角色。研究表明,MADS-box成员通过相互间的作用或与其他转录因子互作形成了一个复杂的调控网络,主要涉及植物激素信号转导、活性氧平衡、渗透调节、泛素化、DNA甲基化等途径及其之间的协同作用。研究发现,绝大多数MADS-box家族成员参与生长发育调控,尤其是花器官发育,部分成员生物学功能存在冗余性,但其可能在不同的发育阶段、组织类型或环境条件下发挥作用,未来需要更深入地解析这些基因的功能特异性和冗余性,以揭示它们在水稻生长发育中的独特作用。然而,水稻MADS-box家族仍然有众多成员的功能尚不清楚,需要更多研究去揭示它们的作用。值得注意的是,部分水稻MADS-box成员展示了潜在的应用价值,通过引导编辑技术和重离子辐射诱变等方法,高效利用这些基因资源去改良水稻的产量、品质和抗逆性等性状,是未来研究的重要方向。本文综述水稻MADS-box转录因子生物学功能,以期为水稻分子育种提供策略。The plant MADS-box transcription factors constitute a class of proteins that possess the MADS-box structural domain.These proteins play crucial roles in regulating plant growth and development,as well as in responding to adversity.The biological functions of rice MADS-box transcription factors have gained significant attention,leading to numerous research advancements.The functions of at least 33 of the 75 known rice MADS-box family members have been studied and reported,and they play pivotal roles in flower development,spikelet development,plant height morphogenesis,root development,flowering habit,seed development,and responses to both biotic and abiotic stresses,such as drought,salinity,high temperature,low temperature,and rice blast.Research has shown that MADS-box members form a complex regulatory network by interacting with each other or with other transcription factors,which mainly involves phytohormone signaling,reactive oxygen species homeostasis,osmotic adjustment,ubiquitination,DNA methylation and the synergistic effects among them.It was found that most MADS-box family members are involved in the regulation of growth and development,especially flower development,and there is redundancy in the biological functions of some of them,but they may play roles in different developmental stages,tissue types,or environmental conditions,and more in-depth analysis of the functional specificity and redundancy of these genes is needed in the future in order to reveal their unique roles in the growth and development of rice.However,there are still numerous members of the rice MADS-box family whose functions are unknown,and more research is needed to reveal their roles.Notably,some rice MADS-box members show potential application value,and the efficient utilization of these genetic resources to improve traits such as yield,quality,and stress tolerance of rice through prime editing and heavy ion beam irradiation mutagenesis technology is an important direction for future research.In this paper,we summarize the biologi
