Abstract:
Low-temperature environments cause chilling injury in horticultural crops and accelerate quality deterioration after rewarming, which is closely related to epigenetic modifications. Epigenetic regulation is widely involved in various aspects of cold responses in horticultural crops, including the expression of cold-tolerant proteins, dynamic changes in cell membranes, energy metabolism, and reactive oxygen species metabolism. With the emergence and development of new scientific technologies, uncovering the secrets of epigenetic regulation in horticultural crop quality is becoming possible. Therefore, this paper reviews the types, roles, and potential mechanisms of epigenetic modifications involved in cold stress responses in horticultural crops, summarizes the dynamic changes and effects of exogenous treatments on epigenetic modifications, and discusses the feasibility of new editing technologies in epigenetic research and applications. This review aims to elucidate the complex regulatory mechanisms of epigenetic control in cold responses in horticultural crops, providing a theoretical foundation for developing novel strategies to control quality decline in horticultural crops.

Transcription
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.
