Association of the tomato co-chaperone gene <i>Sldnaj</i> harboring a promoter deletion with susceptibility to Tomato spotted wilt virus (TSWV).

ABSTRACT: Tomato spotted wilt virus (TSWV) poses a significant threat as a devastating pathogen to the global production and quality of tomato (Solanum lycopersicum). Mining novel resistance genes within the tomato germplasm is an effective and environmentally friendly approach to combat TSWV. In this study, we investigated the mechanisms underlying high TSWV resistance in a specific tomato line after experimental inoculation, despite not possessing any known TSWV resistance genes. The candidate causal genes of disease resistance traits were finely mapped by constructing different genetic populations and performing bulk segregant analysis sequencing. This approach identified SlDnaJ (Solyc10g081220) as a key locus potentially regulating TSWV resistance. We determined a structural varian
