Cold Stress-Induced DNA Methylation Profiling and Its Association with Terpenoid Biosynthesis in Germinating <i>Mikania micrantha</i> Seeds

Mikania micrantha, a highly invasive weed, faces constraints on its northward range expansion in South China due to low winter temperatures. Although DNA methylation is increasingly recognized as a mediator of plant stress adaptation, it remains unknown whether epigenetic regulation couples c
