Abstract

RAPD analysis was performed from four host-specific toxin (HST) producing Alternaria, i.e., A. kikuchiana, A. mali, a. longipes and A. Longipes and A. alternata f. sp. lycopersici, nonpathogenic A. alternata and A. brassicicola to assess their phylogenetic relationship. DNA polymorphism was detected among species (pathotypes) of HST producing Alternaria by PCR amplification and differentiation of the species was recognized by RAPD analysis. Primer OPA-02 was the most profitable among 7 notificated primers for differentiation of the HST producing Alternaria species. UPGMA analysis of the RAPD bands from alternaria spp. revealed that HST producing Alternaria and nonpathogenic a. alternata are closely related.
