Spot blotch (SB), caused by the necrotrophic fungal pathogen Cochliobolus sativus, is an important disease of barley globally. Following transcriptional changes of salicylic acid (SA)-interacting/binding proteins during C. sativus infection may greatly advance understanding the defense crucial signaling pathways. In this study, changes of four known categories of defense; phosphorylation, ROS, PR proteins and nucleotide-binding sites encoded by genes involved in SA–mediated defense signaling networks were studied in compatible/incompatible barley-SB interactions. The functional categories showed significant differential accumulations when compared to the noninoculated controls, and they were primarily upregulated during fungal infection in the resistant cultivar compared with the susceptible one. However, SA profiling of resistant and susceptible cultivars indi.. View More»
