Methylation of cytosine is a conserved epigenetic modification that maintains the dynamic balance of methylation in plants under the regulation of methyltransferases and demethylases. In recent years, the study of DNA methylation in regulating the growth and development of plants and animals has become a key area of research. This review describes the regulatory mechanisms of DNA cytosine methylation in plants. It summarizes studies on epigenetic modifications of DNA methylation in fruit ripening, development, senescence, plant height, organ size, and under biotic and abiotic stresses in horticultural crops. The review provides a theoretical basis for understanding the mechanisms of DNA methylation and their relevance to breeding, genetic improvement, research, innovation, and exploitation of new cultivars of horticultural crops.
胞嘧啶甲基化是一种保守的表观遗传修饰，在甲基转移酶和去甲基化酶的调控下维持植物体内甲基化的动态平衡。近年来，DNA甲基化在调控动植物生长发育方面的研究已成为一个关键研究领域。本综述描述了植物中DNA胞嘧啶甲基化的调控机制。总结了园艺作物果实成熟、发育、衰老、株高、器官大小以及在生物和非生物胁迫下DNA甲基化表观遗传修饰的研究。该综述为理解DNA甲基化机制及其与园艺作物新品种的育种、遗传改良、研究、创新和开发的相关性提供了理论基础。
