Abstract:
As the second most cultivated crop group, legumes occupy vast cultivated areas and hold immense agricultural economic value. DNA methylation, a highly conserved epigenetic modification in legumes, is dynamically regulated by various methylation enzymes. In recent years, investigating the functional roles of DNA methylation in legumes has emerged as a pivotal research area, yet comprehensive reviews in this area remain limited. This review discusses de novo DNA methylation in plants, along with the dynamic mechanisms governing its maintenance, recognition, and removal, and further explores the applications of DNA methylation in legume domestication and improvement; its role in responses to biotic and abiotic stresses, and its impact on genomic stability and transcriptional regulation. Additionally, this review highlights the potential of DNA methylation in advancing legume breeding. By synthesizing current knowledge, this review provides valuable theoretical insights into the application of DNA methylation for legume improvement and genome optimization. It also offers valuable guidance for leveraging epigenetic modifications in legume breeding, improving nitrogen fixation efficiency, and regulating the expression of vital plant proteins.

Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

Phase II Reactions: Methylation Reactions
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...
