Gene Expression Analysis of Induced Plum pox virus (Sharka) Resistance in Peach (Prunus persica) by Almond (P. dulcis) Grafting.

ABSTRACT: No natural sources of resistance to Plum pox virus (PPV, sharka disease) have been identified in peach. However, previous studies have demonstrated that grafting a "Garrigues" almond scion onto "GF305" peach rootstock seedlings heavily infected with PPV can progressively reduce disease symptoms and virus accumulation. Furthermore, grafting a "Garrigues" scion onto the "GF305" rootstock has been shown to completely prevent virus infection. This study aims to analyse the rewiring of gene expression associated with this resistance to PPV transmitted by grafting through the phloem using RNA-Seq and RT-qPCR analysis. A total of 18 candidate genes were differentially expressed after grafting "Garrigues" almond onto healthy "GF305" peach. Among the up-regulated genes, a HEN1 homolog
