Fleshy fruits are major sources of necessary nutrients in many diets worldwide. Most fruit quality attributes emerge during ripening making the fruit more attractive to consumers. Understanding the molecular regulatory network underpinning fleshy fruit ripening is important not only for fruit quality improvement but also for postharvest shelf life. The phytohormone ethylene plays an essential role in climacteric fruit ripening and a number of studies have demonstrated that ethylene signaling components and related transcription factors are involved in the regulation of fruit ripening. However, the transcriptional network by which ethylene interacts with other signaling pathways to regulate the ripening process is not fully understood. In this review, focusing on the tomato as a reference species, the key points regarding the role of ethylene in coordinating the ripening process at the molecular and physiological levels are described. The interplay between ethylene and ripening‐related regulators and its crosstalk with other phytohormones and present recent data on ripening‐related epigenetic modifications are also discussed. Overall, the paper summarizes the most advanced research progress in this area to help facilitate its future development.

乙烯在果实成熟中的分子调控

肉质水果是全球许多饮食中必需营养素的主要来源。大多数水果品质属性在成熟过程中显现出来，使水果对消费者更具吸引力。了解支持果肉成熟的分子调控网络不仅对于改善水果质量而且对于收获后的货架期都很重要。植物激素乙烯在更年期的果实成熟中起着至关重要的作用，许多研究表明，乙烯信号传导成分和相关的转录因子参与了果实成熟的调控。但是，乙烯与其他信号传导途径相互作用以调节成熟过程的转录网络尚未完全被理解。在这篇评论中，我们重点关注番茄作为参考物种，描述了乙烯在分子和生理水平上协调成熟过程中的作用的关键点。还讨论了乙烯与成熟相关调节剂之间的相互作用及其与其他植物激素的串扰，并提供了有关成熟相关表观遗传修饰的最新数据。总体而言，本文总结了该领域最先进的研究进展，以帮助促进其未来发展。
