Research Interests

Working in the area of plant-microbe interactions to understand the complex interaction between soil, microbes and plants. Group is working on the importance of rhizosphere competent plant growth promoting microbes for enhancing plant productivity and soil fertility. By combining fundamental genomic and ecological research perspectives significant contributions made in this important domain not only from the perspective of basic science to understand the role of plant associated bacteria in determining plant gene function but also from the angle of commercial exploitation of the leads obtained through development of products and associated technologies for enhanced crop yield under abiotic and biotic stresses.

 

 

Current R&D activities of the lab include:

     Screening and characterization of microbes with plant growth promoting attributes

     Physiological and molecular mechanisms of microbes involved in plant growth promotion

     Signalling among microbes and plants

     Microbial ecologyof agricultural soils using metagenomics approach

     Microbes mediated stress ameliorating plant gene(s), protein(s) and metabolite(s) during their interaction

     Decipher the mechanism of microbial endophytes mediated induction insecondary metabolite production, stress tolerance and growth promotion.

     Development of microbes based biostimulants and biopesticides
