脱落酸 (ABA) 是非跃变型水果成熟和品质的主要调节剂。草莓因其广泛的遗传学研究和已被证明适用于转基因方法来了解基因功能而被视为一种非跃变型水果的模型。草莓研究对颜色、风味发展和果实软化的研究做出了贡献，近年来ABA已被确定为草莓果实成熟的核心调节剂，而乙烯在跃变型果实中发挥着这一作用。尽管存在这一重大差异，但草莓中相互作用的基因调控网络的几个组成部分（例如 MADS-box 和 NAC 转录因子）与更年期水果中的相似。在这篇综述中，我们总结了在理解 ABA 生物合成和信号传导以及转录因子和其他植物激素的调控网络在草莓果实成熟中的作用方面的最新进展。除了提供其成熟的最新信息外，我们还讨论了草莓研究如何帮助人们更广泛、更全面地了解非跃变型果实成熟的机制，并重点关注草莓作为成熟研究模型平台的使用。
Abscisic acid (ABA) is a dominant regulator of ripening and quality in non-climacteric fruits. Strawberry is regarded as a model non-climacteric fruit due to its extensive genetic studies and proven suitability for transgenic approaches to understanding gene function. Strawberry research has contributed to studies on color, flavor development, and fruit softening, and in recent years ABA has been established as a core regulator of strawberry fruit ripening, whereas ethylene plays this role in climacteric fruits. Despite this major difference, several components of the interacting genetic regulatory network in strawberry, such as MADS-box and NAC transcription factors, are similar to those that operate in climacteric fruit. In this review, we summarize recent advances in understanding the role of ABA biosynthesis and signaling and the regulatory network of transcription factors and other phytohormones in strawberry fruit ripening. In addition to providing an update on its ripening, we discuss how strawberry research has helped generate a broader and more comprehensive understanding of the mechanism of non-climacteric fruit ripening and focus attention on the use of strawberry as a model platform for ripening studies.
