It was shown that the coexistence of high mono – methylation levels of lysine 4 of histone H3 is considered a signature of enhancers. Gene expression could be altered by epigenetic and some biotic and abiotic stresses. Some sugars, hormones or amino acids could also alter gene expression. However, some investigators have shown that increased methylation at promoters was associated with down – regulated protein – coding gene expression . In genomic DNA methylation levels, it was found 24 nt small RNAs only were correla
