Sampa Das

Sampa Das is an Indian biotechnologist, scientist, and an expert on public sector agricultural biotechnology. She is a fellow of the Indian National Science Academy (FNA) and the National Academy of Sciences, India (FNASc). Currently, she is Senior Professor and Head of the Division of Plant Biology at Bose Institute in Kolkata, which is a multi-disciplinary research institution focused on science and technology. She has studied expression of agronomically important genes in crop plants.

She has worked on development of insect resistant transgenic rice, chickpea and mustard plants free of antibiotic resistant selection marker through the expression of mannose binding monocot plant lectins and different Bt toxin genes. She has studied the molecular interaction between receptor proteins identified from target insects and insecticidal lectins as well as different Bt proteins.

Dr. Das has worked on developing understanding of the mechanism of defense response in plants when challenged by various fungal and bacterial pathogens. Isolation and characterization of differentially expressed defense response related genes, proteins from rice and chickpea plants detected at early stage of infection by Fusarium oxysporum f.sp.ciceris and Xanthomonas oryzae pv oryzae, respectively.

She has worked on identification, characterisation and purification of few insecticidal lectins and other proteins from plant sources and isolation and cloning of effective insecticidal lectin and other protein coding gene(s) from respective plant genome(s).

Dr. Das has worked on establishment of efficient plant regeneration and transformation protocol for mustard, chickpea and pigeonpea. Other areas of interest are construction of a number of vectors with different T-DNA border elements for a better understanding of mechanism of T-DNA integration into host plant and construction of chimeric Bt, protease inhibitor gene (s) and other agronomically important gene(s) constructs for their expression in important crops namely, rice and mustard for increased productivity.

Awards and honors In 2007, she became a fellow of the Indian National Science Academy and two years later she became a fellow of the National Academy of Sciences India.
