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 understand 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 understandings of the mechanism of non-climacteric fruit ripening and focus attention on the use of strawberry as a model platform for ripening studies.

脱落酸调控非跃变型典型果实草莓成熟和品质的作用

脱落酸 (ABA) 是非跃变型果实成熟和品质的主要调节因子。草莓被认为是一种典型的非跃变性水果，因为它进行了广泛的遗传研究，并证明适合用转基因方法来了解基因功能。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起着这种作用。尽管存在这一重大差异，但草莓中相互作用的遗传调控网络的几个组成部分，例如 MADS-box 和 NAC 转录因子，与在跃变型水果中运作的那些相似。在这篇评论中，我们总结了了解 ABA 生物合成和信号转导的作用以及转录因子和其他植物激素在草莓果实成熟中的调控网络方面的最新进展。除了提供其成熟的最新情况外，我们还讨论了草莓研究如何帮助对非跃变性果实成熟机制产生更广泛和更全面的理解，并将注意力集中在草莓作为成熟研究模型平台的使用上。
