The genomic
DNA amplification of ITS region of different
isolates yielded a fragment of approximately 650 bp
(FIG. 1). The variability within the amplified regions
was also analyzed by cleaving the fragment with
different restriction enzymes (Data not shown). The
restriction enzymes EcoR I, Sau3A I, Alu I and Cla I gave identical pattern for all isolates and produced
two fragments of different sizes at single cut. The
enzymes Hap II, Msp I and Taq I have multiple
cleavage sites in ITS amplified product and produced
fragments less than 100 bp in size. The enzymes Apa
I, Hind III and Sac I failed to cleave the ITS region
