Development of a Multispecies Bacterial Consortium to Control Fusarium Infection and Deciphering Its Epigenetic Regulation Under Elevated Humidity in Tea Camellia sinensis

Avishek Banik of Presidency University in India will identify a bacterial consortium that can protect tea crops from Fusarium fungal pathogens. The global rise in temperature threatens tea crops in part through increased humidity that favors proliferation of disease-causing Fusarium. To develop a biocontrol strategy for these pathogens, they will isolate Fusarium species from tea plants in tea plantations in the Dooars region of West Bengal as well as bacteria growing on and in the plants. They will use these isolates to characterize the fungal disease process in high-humidity growth conditions in the laboratory and to screen for bacteria that can inhibit it. They will characterize the mechanism of inhibition, including analysis of plant gene regulation, to guide development of an antifungal bacterial product.
