Channa punctatus is a freshwater fish belonging to family Ophiocephalidae. This fish is available in almost all over the country. In present communication molecular study of COI region of mitochondrial gene was done to find out intraspecific differences in genome of Channa punctatus habitating in different states of India having variable environmental conditions. Result showed minor variations ...

To elucidate the Anopheles nuneztovari s.l. taxonomic status at a microgeographic level in four malaria endemic localities from Antioquia and Córdoba, Colombia, fragments of the cytochrome oxidase subunit I (COI) and the white gene were used. The COI analysis showed low genetic differentiation with fixation index (F(ST)) levels between -0.02-0.137 and Nm values between 3-∞, indicating the prese...

BACKGROUND The mitochondrial gene COI has been widely used by taxonomists as a standard DNA barcode sequence for the identification of many animal species. However, the COI region is of limited use for identifying certain species and is not efficiently amplified by PCR in all animal taxa. To evaluate the utility of COI as a DNA barcode and to identify other barcode genes, we chose the aphid sub...

Background Systematic reviews are increasingly used to inform health policy-making. The conflicts of interest (COI) of the authors of systematic reviews may bias their results and influence their conclusions. This may in turn lead to misguided public policies and systems level decisions. In order to mitigate the adverse impact of COI, scientific journals require authors to disclose their COIs. ...

The genus Toxares Haliday, 1840 is a small taxon of Aphidiinae, consisting four valid species in the world. One recorded as new to science from South Korea, this study. Descriptions and illustrations species, T. koreanus sp. nov. , are provided, together with their mitochondrial cytochrome c oxidase subunit I (COI) D2 region nuclear gene for 28S rRNA ( ) sequences. phylogenetic tree reconstruct...

Two new Uromunna species, mundongensis sp. n. and jejuensis n., are described from the Korean Peninsula, representing first record of genus in waters. Genetic analyses using two mitochondrial (COI, Cytb) one ribosomal (18S rRNA) gene allowed us to confirm high pair-wise interspecific differences with establishment reliable barcoding gaps COI (19.9%) 18S (0.4%) between species. Finally, phylogen...

Here we report the first distribution record of genus Micromeriella Betrem, 1972 (Hymenoptera, Scoliidae) from archipelago Malta, based on two specimens aurolea (Klug, 1832) collected island Gozo. Although this species is relatively well distributed in Afrotropical and Palaearctic regions, extend its to central Mediterranean islands. Molecular barcoding using cytochrome c oxidase subunit I (COI...

DNA-based identification system using the mitochondrial cytochrome oxidase subunit I (COI) gene has enabled validation of many species in certain taxonomic groups. These primer combinations were able to work universally across Insecta. Here, a set of three primer pairs were successful in amplifying COI of Mansonia annulata mosquito, a potential vector of Brugia malayi. By merging all three ampl...

Genetic tools have greatly aided in tracing the sources and colonization history of introduced species. However, recurrent introductions and repeated shuffling of populations may have blurred some of the genetic signals left by ancient introductions. Styela plicata is a solitary ascidian distributed worldwide. Although its origin remains unclear, this species is believed to have spread worldwid...

In the present study, sequences of COI gene insects belong to five orders collected from seven cities in Kurdistan province Iran with other locations word was studied.
