WELCOME TO SHARMA LAB

Our laboratory is interested in learning the molecular mechanisms involved in photomorphogenesis and plant development with tomato (Lycopersicon esculentum) as a model system. The current research in our lab is focussed on the following lines

• Molecular analysis of Photomorphogenesis

• Molecular genetics of plant development using tomato mutants

PhD and Post-doctoral positions
