Multi-omics association analysis revealed the role and mechanism of epialleles in environmental adaptive evolution of .

Epialleles, generally referring to alleles whose expression is altered due to differential DNA methylation levels, have important roles in plant morphology, development, and various physiological processes. However, the influence of environmental factors on the plant epialleles under natural conditions is unclear. Meanwhile, the role and mechanism of epialleles in the environmental adaptive evolution of plants remain elusive.
