Salient Research Achievements
(in bullets)
  • Complete genomes sequencing of banana bunchy top virus, banana bract mosaic virus, banana streak Mysore virus and banana streak OL virus was done
  • Coat proteins of BBTV, BBrMV, BSMYV and CMV were expressed in bacterial system and produced polyclonal antisera for diagnosis.
  • PCR, RT-PCR, Multiplex PCR, NASH and ELISA based detection technologies have been developed for the detection of banana viruses.
  • Developed virus genome derived promoter constructs, RNAi constructs for using replicase gene of BBTV, RNAi construct for multiple virus genes (BBTV, CMV and BBrMV) besides rep and cp gene construct for BBTV.
  • Developed 13 transgenic lines of Hill banana resistant to BBTV throughAgrobacterium mediated genetic transformation
  • Developed management technology for bract mosaic virus disease.
  • As accredited Molecular Virology lab virus testing is being done for TC banana plants.
Current Research
  • Molecular approaches to understand the host-virus-vector-environment interactions and RNAi for the management of banana viruses (PI)
Current Research
  • National Certification system for tissue culture raised plants - Virus Indexing component (PI)
  • Development and utilization of diagnostics to viruses of banana under Consortium Research Platform on Vaccines and Diagnostics (PI)
  • Knocking out the virus – Elimination of the endogenous banana streak viral sequences from banana through genome editing with CRIPSPR – Cas9 system (PI)
  • Biotechnological interventions through RNAi approach for management of banana bunchy top virus in NE region of India (PI)
Area of Interest Molecular characterization of viruses, Development of on-site diagnostic kits, Biotechnological approaches for virus disease management, ‘Omics’ - studies to understand host-virus-vector interactions
