To review the mechanisms by which dynamic DNA methylation modulates plant immune responses and pathogen interactions under biotic stress.
Synthesized literature on cytosine and adenine DNA methylation dynamics in plants exposed to viruses, bacteria, fungi, oomycetes, and herbivorous insects.
Evaluated molecular mechanisms across model systems and horticultural crops, focusing on tomato, chrysanthemum, and citrus.
Pathogen exposure induces dynamic methylation shifts that either stimulate host defense activation or promote host susceptibility via pathogen effector manipulation.
Pathogen effectors target host methylation machinery, facilitating transgenerational epigenetic immune memory across plant generations.
