Sharka disease, caused by the plum pox virus (PPV), negatively impacts stone fruit production, resulting in economic losses. It has been demonstrated that grafting almond (Prunus dulcis (Miller) D.A. Webb) variety ‘Garrigues’ into susceptible peach persica (L.) Batsch) rootstocks can result PPV resistance. The molecular circuits related to Prunus species, however, have not fully investigated. In this study, ‘GF305’ were either heterografted with or homografted same cultivar. Peach samples collected at two stages of scion development, ungrafted plants utilized as controls. Profiles transcripts, small RNAs (sRNAs), and DNA methylation obtained analyzed on a genome-wide scale. Homografting heterografting significantly altered transcriptome methylome rootstocks, these modifications being more pronounced during early development. profiles sRNAs impacted when almonds used opposed peaches, likely due transmission PPV-unrelated viral sequences. Gene expression differences from alterations are thoroughly documented promoter sequences genes than within their bodies. This study suggests triggers complex defense response rootstock, potentially involving interplay epigenetic RNA-mediated priming antiviral defenses, which ultimately may contribute
