Epigenetics encompasses all changes in gene expression that occur without alterations to the DNA sequence. These modifications involve DNA methylation, histone modifications, and ncRNA pathways. Plants have evolved remarkable resilience to environmental challenges mediated by epigenetic modifications rather than genetic variation. Epigenetic variation provides a means for designing crop varieties with enhanced resilience to abiotic stresses, such as drought, salinity, and extreme temperatures. By understanding how epigenetic information systems interact among them and with other canonical...
