Designation: 
Senior Scientist (Plant Pathology)

Specialisation: 
Plant Pathology and Agricultural Biotechnology
Qualification: 
Ph D (IIT Kharagpur), Fulbright Scholar (2012-13)
Research Accomplishments: 

1. Pathogen-derived elicitors for inducing resistance: A procedure has been standardized for preparation of pathogen-derived elicitor from the cell wall Fusarium oxysporum f. sp. lycopersici and also from the culture filtrate. As the pathogen-derived elicitors have specific receptors in plants, these elicitors may be used for inducing resistance against Fusarium oxysporum f. sp. lycopersici.

2. Use of hairy roots for studying plant-pathogen interaction: Elicitation of hairy root cultures of tomato with different elicitors evoked same response as was observed in normal roots.

3. Induction of systemic acquired resistance through elicitors: The results indicated that the induced resistance observed in tomato against Fusarium oxysporum f. sp. lycopersici and Ralstonia solanacearum might be a case of systemic acquired resistance. This is a novel endeavour for development of biomolecules which may lead to avoidance of pesticides.

4. Oxidative burst as indicator of plant susceptibility/resistance to pathogen

5. Establishing the biochemical basis for high susceptibility of tomato plants (cv Arka Saurabh) at flowering stage to Fusarium wilt

6. Accumulation of phenolics and lignin in high amounts, together with higher level activity of major defense enzymes in response to the elicitors, may bolster eggplants in mounting practical and effective resistance against Ralstonia solanacearum, the devastating wilt pathogen.

7. Results indicate that increased level of ROS production coupled with more efficient antioxidative system, lower rate of lipid peroxidation and high lignin deposition in cell wall may contribute to the resistance of tomato plants to Ralstonia solanacearum.

Awards & Recognitions, Patents, Inventions, etc: 

An elicitor, derived from Fusarium oxysporum f. sp. lycopersici, has been found effective in inducing resistance against the tomato wilt pathogen. It has been proved for the first time in India that the hairy roots can be used as a model system for studying plant and root pathogen interactions.
