Molecular Characterization of Verticillium dahliae Isolates in
Southern Turkey
Abstract:
PCR products amplified from genomic DNA of the 21 pathogenic V. dahliae
isolates from both different provinces and Vegetative Compatibility Groups (VCGs)
were characterized by RAPD analysis. Of 20 primers tested, five primers produced
polymorphic amplification patterns. Phylogenetic analysis indicated two distinct
clusters. The first cluster contained 8 isolates belonging to VCG2B and one
isolate belonging to VCG4B. The second cluster contained 8 isolates belonging to
VCG2A and one isolate belonging to VCG2B of V. dahliae. RAPD-PCR analysis
was mostly suitable to differentiate V. dahliae isolates based on VCGs or
subgroups. Because all VCG2B isolates from cotton except one were identified as
members of cluster one and all VCG2A isolates belonged to the second cluster.
Supporting this conclusion, one isolate belonging to VCG4B and the Heterokaryon
Self-incompatible (HSI) isolate, never included in both clusters.
