The Histone Marks Signature in Exonic and Intronic Regions Is Relevant in Early Response of Tomato Genes to and in miRNA Regulation.

Research into the relationship between epigenetic regulation and resistance to biotic stresses provides alternatives for plant protection and crop improvement. To unravel the mechanisms underlying tomato responses to , we performed a chromatin immunoprecipitation (ChIP) analysis showing the increase in H3K9ac mark along the early induced genes , , and encoding oxylipin-pathway enzymes, and coding for a transcriptional regulator of hormonal signaling. This histone mark showed a more distinct distribution than the previously studied H3K4me3.
