Research Areas

  • Plant Molecular Biology
  • Lipid Metabolic Engineering
  • Biotechnology of Plants, Fungi and Algae
  • Functional Genomics of Rice Crop
  • Bioprospecting of Endophytic Microbes
Research & Development activities of Molecular Genetics & Transgenesis Laboratory can be grouped into three major domains. (A) Metabolic engineering of plants, fungi and algae for qualitative and quantitative improvement of storage-lipids: This program aims to improve the quality and quantity of storage-lipids for edible purpose and biodiesel applications. Genetically modified Brassica juncea and Oryza sativa have been developed for seed-specific expression of transgenes to achieve the nutritionally desirable fatty acid profile in mustard oil and rice bran oil, respectively. We are also working on increasing the storage-lipid productivity in these two crops. Our group has isolated a few oleaginous fungi including yeasts from plant and rhizosphere, and characterized certian critical genes for increasing the lipid productivity. Currently, metabolic engineering of microalgae is being pursued to develop algal strains with enhanced lipid productivity. (B) Functional genomics of rice crop for improved productivity and grain quality: Our aim is to improve the grain productivity and low/no arsenic-accumulating rice grains. Transgenic rice lines with improved agronomic traits (e.g., semi-dwarfism, tolerance against biotic and abiotic stresses) have been developed. We have generated transgenic rice plants with reduced arsenic and cadmium content in grains. Furthermore, our research group is also involved in genomics-supported screening of aromatic rice cultivars with superior yield-attributing traits to be grown in local agro-climatic zones. (C) Bioprospecting of endophytic microbes for animal health care and plant growth promotion: We are exploring the laboratory-isolated endophytic fungi (obtained from edible plant parts and medicinal plants) for identification of metabolites having bioactive properties such as antimicrobial, quorum sensing inhibitory and antioxidant compounds. We are also working on the genomics and metagenomics of plant associated microbial community to understand the plant growth promoting features of these bacteria and fungi, so as to develop biotechnological strategies for improving the health of animal and plant.
