DNA Methylation in Plants

DNA methylation in plants is an epigenetic modification involving the addition of a methyl group to DNA, primarily affecting gene expression without altering the DNA sequence. This process is crucial in regulating plant development, stress responses, and defense mechanisms. Methylation patterns can be inherited, allowing plants to "remember" and better respond to previous stressors. Environmental factors can alter methylation patterns, contributing to phenotypic plasticity. Research in DNA methylation helps in breeding programs focused on stress-resistant and high-yield plants, as methylation control mechanisms can be utilized for improved crop resilience.
