Identification of Molecular and Biochemical Variations in Alternaria spp

Abstract

A total of eight species of Alternaria denoted by nine isolates were collected from diverse crops and variation among them was examined by protein profiling and RAPD-PCR techniques. Most of the isolates amplified similar bands of DNA which were used as measures of the degree of resemblance among isolates. The phylogenetically linked out group genus Stemphylium could not be clearly separated using RAPD analysis. No correlation was found between RAPD cluster analysis and pathogenic abilities of the isolates tested.
