Molecular mechanisms of plant-insect interaction
Tzin lab - Ben Gurion University of the Negev
Our lab focuses on understanding the molecular mechanisms of plant resistance to insect damage. Our goal is to discover the novel genes and metabolites that affect plant defense in response to pest attack and to use these findings to increase crop yields and to ensure global food security. This is a fascinating and vibrant field of research that allows scientists from varied disciplines of plant biology, analytical chemistry, entomology, and chemical ecology to work together and address this important question. I strongly believe that our discoveries will have the potential to be utilized towards enhancing nutritional quality and improving sustainable agriculture.
