Sheath blight disease (ShB), caused by the fungus Rhizoctonia solani is one
of the most destructive diseases of rice (Oryza sativa L.), causing
substantial yield loss in rice. Researchers, led by Richa Kamboj from the
National Research Centre on Plant Biotechnology, cloned the rice chitinase
gene LOC_Os11g47510 from R. solani-tolerant line Tetep and inserted it into
the ShB susceptible japonica rice line Taipei 309 (TP309).

Analysis confirmed the presence of transgene in transgenic plants. Further
analysis of the transgenic plants showed good correlation between transgene
expression and sheath blight resistance among transformants. Assays then
confirmed the effectiveness of the chitinase gene-mediated resistance in all
the transgenic TP309 plants.

The novel chitinase gene will be of significant use in molecular plant
breeding program for developing sheath blight resistance in rice.
