摘　　要：Tomato(Solanum lycopersicum)and potato(Solanum tuberosum),two integral crops within the nightshade family,are crucial sources of nutrients and serve as staple foods worldwide.Molecular genetic studies have significantly advanced our understanding of their domestication,evolution,and the establishment of key agronomic traits.Recent studies have revealed that epigenetic modifications act as"molecular switches",crucially regulating phenotypic variations essential for traits such as fruit ripening in tomatoes and tuberization in potatoes.This review summarizes the latest findings on the regulatory mechanisms of epigenetic modifications in these crops and discusses the integration of biotechnology and epigenomics to enhance breeding strategies.By highlighting the role of epigenetic control in augmenting crop yield and adaptation,we underscores its potential to address the challenges posed by a growing global population as well as changing climate.
