摘要
NAC转录因子家族在调节植物的生长发育中发挥着重要的作用,在模式植物、作物中已进行了大量研究,但是在观赏植物中的研究还缺乏系统性的梳理和探讨.本综述介绍了 NAC转录因子的结构和分类,并梳理了 2004-2023年NAC转录因子在观赏植物器官生长发育和胁迫响应上的生物学功能研究,其中观赏植物器官生长发育主要集中在叶缘形态建成、花器官发育、叶片衰老、花瓣衰老、种球休眠5个方面,胁迫响应则集中在干旱、盐、碱、冷、热等非生物胁迫,在生物胁迫中报道较少.最后,鉴于观赏植物NAC转录因子大部分都还停留在生物信息学分析以及表达模式分析等功能初探阶段,本文在结合观赏植物全基因组测序继续开展NAC转录因子鉴定研究、挖掘观赏植物中与模式植物存在不同作用机制的NAC转录因子、解析观赏植物NAC转录因子与其他转录因子间的调控网络、加快利用推进基因工程或编辑技术开展观赏植物的分子育种工作等4个方面,对未来NAC转录因子在观赏植物中的研究提出了展望.
Abstract
The NAC transcription factor family members play important roles in regulating plant growth and development.Many studies have been reported in model plants and crops,but the NAC transcription factors in ornamental plants remain systematically investigated.This review introduces the structure and classification of NAC transcription factors,and summarizes these researches in organ growth and development and stress response during 2004-2023,including five subjects:leaf margin morphogenesis,flower development,leaf senescence,petal senescence,and seed dormancy.Many studies were conducted in response to abiotic stress such as drought,salt,alkali,cold and heat,while the works to biotic stress were rare.Since most studies of the NAC transcription factors in ornamental plants are still preliminary and relying on bioinformatics analysis of family members and their transcriptional profile analysis,we proposed the future prospectives of NAC transcription factors in ornamental plants,including:(1)Identification of NAC transcription factors through taking advantage of the whole genome sequencing datasets;(2)Exploration of the mechanisms of NAC transcription factors in ornamental plants;(3)Investigation of the regulatory network in NAC transcription factors interplaying with other transcription factors;(4)Molecular breeding of ornamental plants based on genetic engineering or genome editing technologies.
