Arabidopsis Methylation

Arabidopsis methylation refers to the addition of chemical groups called methyl groups to its DNA, primarily at specific regions. This process helps regulate gene activity without changing the underlying DNA sequence. In plants like Arabidopsis, methylation is crucial for controlling development, responding to environmental stresses, and silencing unwanted genetic elements like viruses or transposons. Think of methylation as a switch that can turn genes on or off, ensuring proper plant growth and adaptation. This epigenetic mechanism is vital for maintaining genomic stability and facilitating flexible gene expression in response to changing conditions.
