Comprehensive transcriptome analysis and functional characterization of PR-5 for its involvement in tomato Sw-7 resistance to tomato spotted wilt tospovirus.

ABSTRACT: Tomato spotted wilt tospovirus (TSWV), one of the most important plant viruses, causes yield losses to many crops including tomato. The current disease management for TSWV is based mainly on breeding tomato cultivars containing the Sw-5 locus. Unfortunately, several Sw-5 resistance-breaking strains of TSWV have been identified. Sw-7 is an alternative locus conferring resistance to a broad range of TSWV strains. In an effort to uncover gene networks that are associated with the Sw-7 resistance, we performed a comparative transcriptome profiling and gene expression analysis between a nearly-isogenic Sw-7 line and its susceptible recurrent parent (Fla. 8059) upon infection by TSWV. A total of 1,244 differentially expressed genes were identified throughout a disease progression process involvi
