Effect of EGTA and Trifluoperazine dihydrochloride (TFP) on conidial germination of Marssonina coronaria

We present evidence that treatment of Marssonina coronaria conidia with different concentrations of EGTA and anti-calmodulin drug Trifluoperazine dihydrochloride (TFP) in PPDB resulted in inhibition of spore germination and colony formation. Our study will provide a base to understand the basis of CaM-mediated signaling mechanism in M. coronaria and apple leaf blotch disease development.
