About Photosynthesis Group
The photosynthesis group in school of life sciences, Devi Ahilya University focuses on the light reaction of photosynthesis. As it is known that photosystem II is most susceptible to environmental stress and is the first one to get damaged by abiotic stress such as high temperature, high salt etc. Our interest lies in identifying the primary component which gets damaged first in photosystem II in response to high temperature and high salt stress.
Our group also addresses biochemical and biophysical aspects of effect of anions on the photosynthetic electron transport chain. Ionic environment affects the integrity of thylakoid membranes significantly. Using EPR spectroscopy, fluorescence induction kinetics and low temperature fluorescence emission spectra. We have been able to characterize the site and mode of action of various anions like chloride, nitrite, fluoride, oxalate etc. in the photosynthetic electron transfer chain.
Our group is also involved in characterization of structural and functional heterogeneity of photosystem II in response to various abiotic stresses. Our recent interest includes effects of environmental pollutants like Polycyclic aromatic hydrocarbons (PAH) on photosynthetic performance in crop plants.
