Genomics, Bioinformatics and Plant Disease Resistance

Obtained Post Doctorate training on Genome analysis and bioinformatics at University of Alberta, Edmonton, Canada and Cold Spring Harbor Laboratory, NY, USA.

Dr. T. R. Sharma has contributed extensively to the improvement of rice for over 26 years. His most significant contributions  include,   mapping, cloning  & functional validation of a new Rice blast (Magnaporthe oryzae) resistance gene  Pi-kh (Pi54)  from a unique source,   which  activates complex defense mechanism as demonstrated by microarray analysis.  He has also mined two new alleles Pi54rh and Pi54of   from wild rice,  which are highly resistant to rice blast. He has also successfully mapped a novel QTL qSBR11-1, which has been transferred to Basmati type varieties for imparting resistance to sheath blight. Besides, he has contributed to the sequencing, genome assembly and annotation of   6.7 Mb of  rice  genome, half arm of chromosome 5 of tomato, and Pigeonpea & Mango genomes. He decoded the genomes of   25 races of wheat rust fungus Puccinia tritician, P. graminis tritici  and P. striiformis, and rice blast fungus Magnaporthe oryzae. In addition, he succeeded in identifying 786 disease resistance and 167 defense response genes  in   rice genome for future mining. Dr. Sharma has also developed robust DNA makers tightly linked to blast resistance gene Pi54 which are being used extensively in India and in different countries  to improve rice varieties.  The resistance lines of mega rice varieties, Pusa Basmati -1, Swarna and BPT5204 and more than 20 regional varieties containing Pi54 gene are at various stages of testing across India.  Dr. Sharma has filed six Indian patents. He was   associated in the development of two new rice varieties, Pusa 1637 (containing  blast resistance gene Pi9 and released for cultivation in  Punjab, Haryana and western Utter Pradesh in 2016) and HPR2880 (containing blast resistance gene Pi54 and Pita and released for cultivation in Himachal Pradesh in 2016). Rice blast results in loss of US$ 40.9 million annually in South-East Asia which will be minimized through these resistant varieties.

Understanding molecular basis of plant immunity, decoding genomes of various species and comparative genome analysis among different crops.
