PCR yielded a 710-bp fragment in all specie
The amplicons were digested with seven restriction endonucleases (Hind II, Ava II, Rsa I, Taq I, Hpa II, Tru 1I and Xba I) that were selected based on the preliminary
in silico analysis. (amplified product)
Different levels of polymorphism were detected among samples.
The level of COI variation
revealed using only Hpa II was sufficient to generate easily analyzable species-specific restriction profiles that
could distinguish unambiguously all targeted species.
