Unlike fungal and bacterial diseases, no direct method is available to control viral
diseases. The use of resistance-inducing compounds can be an alternative strategy
for plant viruses. Here we studied the basal response of melon to Melon necrotic
spot virus (MNSV) and demonstrated the efficacy of hexanoic acid (Hx) priming, which
prevents the virus from systemically spreading. We analysed callose deposition and
the hormonal profile and gene expression at the whole plant level. This allowed us to
determine hormonal homeostasis in the melon roots, cotyledons, hypocotyls, stems and
leaves involved in basal and hexanoic acid-induced resistance (Hx-IR) to MNSV. Our
data indicate important roles of salicylic acid (SA), 12-oxo-phytodienoic acid (OPDA),
jasmonic-isoleucine, and ferulic acid in both responses to MNSV. The hormonal and
metabolites balance, depending on the time and location associated with basal and
Hx-IR, demonstrated the reprogramming of plant metabolism in MNSV-inoculated
plants. The treatment with both SA and OPDA prior to virus infection significantly
reduced MNSV systemic movement by inducing callose deposition. This demonstrates
their relevance in Hx-IR against MNSV and a high correlation with callose deposition.
Our data also provide valuable evidence to unravel priming mechanisms by natural
compounds. [-]
