Testing the potential of proposed DNA barcoding markers in Nezara viridula and Nezara antennata when geographic variation and closely related species were considered
Journal of Insect Science 14 (79), 1-11
Abstract: The COI gene as the core of the DNA barcoding system for animals has received significant attention. The observed wide overlap between intra- and interspecific sequence variability has led researchers to envisage the primary COI-based method. The sequences of 16S rDNA, COI, and Cyt b genes of Nezara viridula (L.) (Hemiptera: Pentatomidae) from 13 countries and the same sequences of N. antennata Scott were chosen as molecular markers to analyze the intra- and interspecific relationships between the closely related species in this study. The results support that Cyt b gene may be a good candidate alongside COI, when the combined factors of geographic variation and closely related species are taken into account.
