Epigenetic regulation of organ-specific functions in Mikania micrantha and Mikania cordata: insights from DNA methylation and siRNA integration.

ABSTRACT:

Background

DNA methylation is a crucial epigenetic mechanism that regulates gene expression during plant growth and development. However, the role of DNA methylation in regulating the organ-specific functions of the invasive weed Mikania micrantha remains unknown.

Results

Here, we generated DNA methylation profiles for M. micrantha and a local congeneric species, Mikania cordata, in three vegetative organs (root, stem, and leaf) using whole-genome bisulfite sequencing. The results showed both differences and conservation in methylation levels and patterns between the two species. Combined with transcriptome data, we found that DNA methylation generally inhibited gene expression, with varying effects depending on the genomic region and sequence context (CG, CHG, and CHH). Gen
