Abstract: Male germline cells in plants undergo epigenetic reprogramming mediated by chromatin remodeling, histone modification, DNA methylation, and small RNA during development. Many genes are involved in shaping the epigenetic state of male germline cells and regulating plant male fertility. Recent advances in multi-omics techniques have helped elucidate specific epigenetic profiles of male germline cells at different stages of development. In this review, we summarize recent advances in epigenetic dynamics and molecular mechanisms involved in the development of male germline cells in plants and discuss prospects for future studies on the epigenetic regulation of this developmental process.
