Ripening is one of the most important stages of fruit development and determines the fruit quality. Various factors play a role in this process, with epigenetic mechanisms emerging as important players. Epigenetic regulation encompasses DNA methylation, histone modifications and variants, chromatin remodeling, RNA modifications, and non-coding RNAs. Over the past decade, studies using tomato as a model have made considerable progress in understanding the impact of epigenetic regulation on fleshy fruit ripening and quality. In this paper, we provide an overview of recent advancements in the epigenetic regulation of tomato fruit ripening and quality regulation, focusing on three main mechanisms: DNA/RNA modifications, non-coding RNAs, and histone modifications. Furthermore, we highlight the unresolved issues and challenges within this research field, offering perspectives for future investigations to drive agricultural innovation.
成熟是果实发育最重要的阶段之一，决定了果实的品质。各种因素在这个过程中发挥作用，表观遗传机制作为重要的参与者出现。表观遗传调控包括 DNA 甲基化、组蛋白修饰和变体、染色质重塑、RNA 修饰和非编码 RNA。在过去的十年中，以番茄为模型的研究在理解表观遗传调控对肉质果实成熟和品质的影响方面取得了相当大的进展。本文综述了番茄果实成熟和品质调控中表观遗传调控的最新进展，重点介绍了三种主要机制：DNA/RNA 修饰、非编码 RNA 和组蛋白修饰。此外，我们还强调了该研究领域中尚未解决的问题和挑战，为推动农业创新提供了未来研究的视角。
