A comparative proteomic analysis between two near-isogenic rice lines, displaying a resistant and susceptible phenotype upon infection with Magnaporthe oryzae was performed. We identified and validated factors associ-ated with rice disease susceptibility, representing a flourishing source toward a more resolute rice-blast resis-tance. Proteome profiles were remarkably different during early infection (12 h post-inoculation), revealing several proteins with increased abundance in the compatible interaction. Potential players of rice susceptibility were selected and gene expression was evaluated by RT-qPCR. Gene Ontology analysis disclosed susceptibility gene-encoded proteins claimed to be involved in fungus sustenance and suppression of plant immunity, such as sucrose synthase 4-like, serpin-ZXA-like, nudix hydrolase15, and DjA2 chaperone protein. Two other candidate genes, picked from a previous transcriptome study, were added into our downstream analysis including pyr-abactin resistant-like 5 (OsPYL5), and rice ethylene-responsive factor 104 (OsERF104). Further, we validated their role in susceptibility by Transient-Induced Gene Silencing (TIGS) using short antisense oligodeoxyr-ibonucleotides that resulted in a remarkable reduction of foliar disease symptoms in the compatible interaction. Therefore, we successfully employed shotgun proteomics and antisense-based gene silencing to prospect and functionally validate rice potential susceptibility factors, which could be further explored to build rice-blast resistance. Significance: R gene-mediated disease resistance is race-specific and often not durable in the field. More recently, advancements in new breeding techniques (NBTs) have made plant disease susceptibility genes (S-genes) a new target to build a broad spectrum and more durable resistance, hence an alternative source to R-genes in breeding programs. We successfully coupled shotgun proteomics and gene silencing tools to prospect and validate new rice-bast susceptibility genes that can be further exploited toward a more resolute blast disease resistance.
