Rice sheath blight (ShB) disease, caused by the fungal pathogen Rhizoctonia solani AG1-IA, is one of the devastating diseases
and causes severe yield losses all over the world. No completely resistant germplasm is known till now, and as a result, the
progress in resistance breeding is unsatisfactory. Basic studies to identify candidate genes, QTLs, and to better understand the
host–pathogen interaction are also scanty. In this study, we report the identification of a new ShB-tolerant rice germplasm, CR
1014. Further, we investigated the basis of tolerance by exploring the disease responsive differentially expressed transcriptome
and comparing them with that of a susceptible variety, Swarna-Sub1. A total of 815 and 551 genes were found to be differentially
regulated in CR 1014 and Swarna-Sub1, respectively, at two different time points. The result shows that the ability to upregulate
genes for glycosyl hydrolase, secondary metabolite biosynthesis, cytoskeleton and membrane integrity, the glycolytic pathway,
and maintaining photosynthesis make CR 1014 a superior performer in resisting the ShB pathogen. We discuss several putative
candidate genes for ShB resistance. The present study, for the first time, revealed the basis of ShB tolerance in the germplasm
CR1014 and should prove to be particularly valuable in understanding molecular response to ShB infection. The knowledge
could be utilized to devise strategies to manage the disease better.
