Fungal phytopathogens cause a significant loss in agricultural yields. Alternaria brassicae and Sclerotinia sclerotiorum are the two major economically important fungal pathogens infecting Brassica juncea, the Indian Mustard. The overall goal of our work is to gain a better understanding of the necrotrophic fungal pathogenesis and the cognate defense responses that will lead to suitable control strategies. We are employing genetic and molecular approaches for identification and functional analysis of novel factors that determine plant susceptibility and/or resistance to Alternaria and Sclerotinia infection. Additionally, role of Arabidopsis non symbiotic Globin in plant defense against necrotrophs is being studied. Ahb1 and Ahb3 have been crystallized in collaboration with Dr Suman Kundu (Prof., Dept of Biochemistry, UDSC) and Dr Pravindra Kumar (IIT Roorkee). Further, physiological role of these proteins in disease resistance is being evaluated. We are also interested in identifying pathogen inducible plant promoters/ enhancers.
