RESUMEN
DNA methylation is an epigenetic modification that forms an important regulation mechanism of gene expression in organisms across kingdoms. Aberrant patterns of DNA methylation can lead to plant developmental abnormalities. In this article, we briefly discuss DNA methylation in plants and summarize its functions and biological roles in regulating gene expression and maintaining genomic stability, plant development, as well as plant responses to biotic and abiotic stresses. We intended to provide a concise reference for further understanding of the mechanism of DNA methylation and potential applications of epigenetic manipulation for crop improvement.

Objective: Using electronic cloning technology to predict cyclophilin gene of Lotus corniculatus. Methods: Using glycine max cyclophilin sequence as probe sequence, based on EST sequence from NCBI and assembled by CAP3 sequence assembly programme, using bioinformatic database and related software, the structure prediction and function analysis were performed. Results: The full length of cyclophilin gene was 1 346 bp, it contained a 771 bp ORF, encoding 256 amino acids, and the protein was a hydrophilic protein. Conclusion: The study is intended to further explain the molecular genetic function theory and experimental basis.
