Spodoptera litura feeding on Arabidopsis thaliana

More than a million herbivorous insect species are known that lead to crop loss worldwide. Plants have evolved sophisticated defense mechanism to counteract these insects co-ordinated majorly by jasmonic acid (JA) dependent signaling cascade. The early events in plant perception of insect attack is largely unexplored and involves recognition of HAMPs or DAMPs.  Using generalist chewing insect Spodoptera litura and its host plant species, such as Arabidopsis and tomato, we intend to unravel the mechanism of action of several early signaling genes that assist the plant in rapid response against the insect attack leading to the activation of systemic signaling.

Major Research Interests:

1.Mechanisms underlying plant perception of insect attack

2. Mechanisms involving plant-microbial symbiont recognition

About the PI

Dr. Jyothilakshmi Vadassery is a scientist at National Institute of Plant Genome Research, Delhi, India. Her group works on plant-biotic interactions especially early signalling upon insect herbivory, calcium signalling and phytohormone signalling pathways. She received her PhD degree in Plant Molecular Biology at Friedrich Schiller University, Jena, Germany. This was followed by postdoctoral positions at Cornell University and Max Planck Institute for Chemical Ecology, Jena, Germany. Her research interests are in calcium signalling upon plant-biotic interactions, plant defence against herbivores, and jasmonate signalling.
