A comprehensive review on epigenetic mechanisms and application of epigenetic modifications for crop improvement

Erosion of genetic diversity due to excessive breeding applications is a major threat to crop species. Plants should be genetically diverse to cope with repercussions of changing climate. Of late, diversity made available through epigenetic changes now appearing to be a novel source for crop improvement. Epigenetics is a phenomenon that alters heritable gene expression without implicating any variation in the genomic DNA sequences. The mechanism...
