Sporisorium sorghi as the incitant of kernel smut disease of sorghum

I studied the fungal plant pathogen Sporisorium sorghi, the causal agent of covered kernel smut disease in Sorghum. I performed detailed studies of environmental factors affecting teliospore germination and mcyelial dry weight, and determined the longevity for teliospore in vitro and in the field, screened of available sorghum cultivars for resistance and detect of the causal organism in plant by light microscopy, ELISA and PCR. The phylogenetic analysis of GAPDH gene of S. sorghi and others published related fungal genera and species was studied. I studied the biological control of smut by isolated microorganisms and commercial products of plant extracts and strengthening were also evaluated.
