Research interest

  1. Plant-Microbe Interactions – Plants possess an ingenious immune system that allows them to defend themselves against biotic and abiotic stress. They are helped by benevolent micro-organisms in the soil. We are focusing on the application and functioning of indigenous rhizosphere associated beneficial microflora and endophytic microbial community prevalent in commercial crop like Tea for plant growth promotion and disease suppression for sustainable crop production. Much of our current work is focused on understanding the fungal pathogens of Tea (Camellia sinensis), molecular diagnosis, mode of infections, and biological control. Our special emphasis is to develop pesticides/herbicides tolerant and/or resistant microbe-based bioformulations of plant growth-promoting Microorganisms (PGPM) for biocontrol of major Tea fungal pathogens, and to investigate the ability of wild-type strains to remove pesticides and herbicides from synthetic culture medium and/or environment.
  2. Microbial Bioactive Metabolites – We are exploring extracellular antimicrobial metabolite/s producing actinobacteria and antibiotic biosynthesis gene/s prevalent in protected forest unique habitats by culturable and metagenomic approaches for development of new drug molecules against MRSA, MDR strains, infectious diseases and dermatophytes. Molecular characterization and genetic diversity for database preparation and preservation of biologically active secondary metabolite/s producing organisms prevalent in unique ecological niches of North-East India is another goal of our research.
