Applied Biodiversity Laboratory 

Research Interests

Genome Mining, Biofuel Crops, IPR 

My lab and research group try to address the research questions in areas of Applied Biodiversity with special reference to bioresources of Northeast India using an integrative approach.

In recent year the global losses in biodiversity and ongoing development pressures on the environment have instigated bio conservation, need of the hour.  Zingiberaceae being a plant family of medicinally important plant species, its conservation is of paramount nature. Along with the conservation the importance of documenting the medicinal usage in folklore is felt so that these valuable leads could be investigated. The conservation of the plant species is incumbent upon its identification which in turn requires an agreeable classification. The work in authors’ laboratory is aimed at documenting the ethno-medicinal usage of plants belonging to this family, construction of a database for dissemination of the knowledge, genome composition and reconstruction of phylogeny using organellar genome (Tushar et al 2010, Das et al 2012; Basak et al 2014). In brief applied biodiversity group is tapping Zingiberaceae from wilderness to mining ‘OMICS’.

Less arable land, weather extremities, increased fuel and energy costs and society sensitivity towards gene transfer are the major impeding hurdles for global agricultural food security. Tapping the potential of biological fuel sources will be key in the future. Research in the author’s laboratory contributes to the genetic, molecular and biochemical knowledge of the tree Pongam (Kesari et al, 2009; Rimjhim et al, 2013; Aadi et al, 2014). In spite of huge potential, many questions remain unanswered about the overall utility of oil-yielding crops as a biofuel feedstock. Step-by step holistic approach is being carried out in the authors group so as to tease out the finer details and set a model biofuel crop for next generation sequencing and genomic diversity studies. Long term objective is to develop, the necessary knowledge and range of technologies to improve biofuel crops with more efficient biofuel and bioenergy.
