多胺调控果实发育的研究进展
Advances in the Regulation of Fruit Development by Polyamines
摘要
Abstract
Polyamines(PAs),a class of small aliphatic nitrogenous bases with high biological activity ubiquitously present in plants,act as important endogenous bioactive substances and exert crucial regulatory effects throughout the entire process of fruit development.Studies have shown that PAs not only directly participate in plant flower bud differentiation,fruit set and fruit development,but also jointly regulate fruit ripening and senescence through interactions with phytohormones such as ethylene.This paper systematically reviews the regulatory roles of PAs in different stages of fruit development,including the effects of dynamic changes in PA concentrations on flower bud differentiation,pollen germination,pollen tube growth,fruit set,and the early stages of fruit development.Meanwhile,it summarizes the regulatory effects of PAs on fruit cell division and expansion,and discusses their roles in modulating the processes of fruit ripening and senescence.In addition,this paper further explores the application potential of PAs in agricultural production,including their value in improving fruit yield,quality and extending shelf life.It also prospects the application of artificial intelligence-assisted gene editing technology for the precise regulation of plant endogenous PA biosynthetic,metabolic and transport pathways to optimize the PA metabolic network and realize fruit quality improvement,thus proposing new strategies for emerging biotechnological research directions such as fruit quality modification and breeding.In conclusion,this paper systematically summarizes the important roles of PAs in all stages of fruit development and deepens the understanding of the PA regulatory network.Concurrently,it discusses the agricultural application of PAs and their integration with emerging technologies,which provides important theoretical support and new ideas for fruit quality improvement and the sustainable development of the fruit industry.关键词
