Dr Anjana Jajoo, School of Life Science, Devi Ahilya University, will present this seminar entitled "Chlorophyll Fluorescence: A quick tool to measure stress in plants" at the James Hutton Institute in Dundee.

Abstract

In nature, plants are exposed to many adverse factors that interfere with the photosynthetic process, leading to decline in growth, development, and yield. Chlorophyll a fluorescence allows valuable information on photochemical properties of leaves to be obtained rapidly. The analysis of fluorescence provides detailed information on the status and function of the photosystem II (PSII) reaction centers, antenna, and both the donor and acceptor sides of PSII. The physiological state of several photosystem II (PSII) components, electron transport chain components, and the cooperation of light-dependent and light-independent biochemical reactions can be evaluated by analysis of chlorophyll fluorescence (ChlF) induction curves. Nowadays, ChlF measurements are a popular method for evaluating the impact of stress factors on photosynthesis. Application of the chlorophyll fluorescence technique is very promising. I shall be discussing its application mainly to identify effects of abiotic stresses like high/low temperature, drought, salinity, nutrient deficiency, UV radiations, environmental pollutants, etc. on crop plants. Scientists from different fields, such as plant physiology, biotechnology, forestry, ecophysiology, and even plant breeders and farmers, are using it to study the structure and function of photosynthetic apparatus.

Biography

Anjana Jajoo is an Associate Professor in School of Life Science of Devi Ahilya University (DAU), Indore, India. She obtained her doctorate degree in Life Science from DAU (1993). She has been doing research in the field of photosynthesis for more than 25 years and acts as editor, referee and member of editorial Board in several international journals. She has authored/co-authored more than 60 research papers, several book chapters, has guided 14 doctorate students and many others are still working under her guidance. She has availed several fellowships from national and international funding agencies in order to carry out research work in several renowned laboratories all over the world including Russia, Hungary, Germany, South Korea, Finland. At the same time, she has completed several national and international collaborative projects. Her research interests include abiotic stress responses in photosynthetic machinery, particularly Photosystem II. She is visiting UK as Common wealth Academic fellow stationed at University of Leeds.
