摘要
就NAC基因结构与功能及对果实发育和成熟的调控作用研究进行了综述,提出NAC转录因子通过乙烯途径和多重激素途径影响果实成熟。乙烯途径包括:乙烯诱导NAC转录因子,NAC转录因子调控乙烯信号系统上游转录因子,和直接调控主要乙烯合成基因影响果实成熟;多重激素途径包括,通过生长素、脱落酸及赤霉素/油菜素内酯等途径,影响果实成熟。
Recent researches on the structure and function of NAC transcription factors（TFs）and their regulating mechanisms during the process of fruit development and ripening are reviewed in this paper. It is suggested that NAC TFs affect fruit ripening through ethylene and multiple hormone pathways. Ethylene pathway includes ethylene induced NAC TFs regulating fruit ripening,NAC TFs regulating the upstream TFs of ethylene signal systems and TFs directly regulating the main ethylene synthesis genes to control fruit maturity. Multiple hormone pathways include TFs affecting fruit maturity via auxin,abscisic acid and gibberellin/brassinolide pathways.
