Rosaceae is a family with an extraordinary spectrum of fruit types, including fleshy peach, apple, and strawberry that provide unique contributions to a healthy diet for consumers, and represent an excellent model for studying fruit patterning and development. In recent years, many efforts have been made to unravel regulatory mechanism underlying the hormonal, transcriptomic, proteomic and metabolomic changes occurring during Rosaceae fruit development. More recently, several studies on fleshy (tomato) and dry (Arabidopsis) fruit model have contributed to a better understanding of epigenetic mechanisms underlying important heritable crop traits, such as ripening and stress response. In this context and summing up the results obtained so far, this review aims to collect the available information on epigenetic mechanisms that may provide an additional level in gene transcription regulation, thus influencing and driving the entire Rosaceae fruit developmental process. The whole body of information suggests that Rosaceae fruit could become also a model for studying the epigenetic basis of economically important phenotypes, allowing for their more efficient exploitation in plant breeding.
蔷薇科是一个果实类型极为多样的科，包括肉质的桃子、苹果和草莓，这些果实为消费者的健康饮食做出了独特贡献，并且是研究果实形态建成和发育的优秀模型。近年来，人们为揭示蔷薇科果实发育过程中发生的激素、转录组、蛋白质组和代谢组变化背后的调控机制付出了诸多努力。最近，一些针对肉质果实（番茄）和干果（拟南芥）模型的研究，有助于更好地理解重要可遗传作物性状（如成熟和应激反应）背后的表观遗传机制。在此背景下，总结迄今获得的结果，本综述旨在收集有关表观遗传机制的现有信息，这些机制可能在基因转录调控中提供额外层面的作用，从而影响并推动整个蔷薇科果实发育过程。所有信息表明，蔷薇科果实也可能成为研究经济重要表型表观遗传基础的模型，有助于在植物育种中更有效地利用这些表型。
