Two cichlid populations each found on separate islands in the Bocas del Toro archipelago, Panama were identified as members the genus Astatheros. DNA from each population was isolated and purified and the mitochondrial gene cytochrome b was used as a molecular marker. Resulting sequences were compared with already published cytochrome b sequences of Astatheros from an internet database. Phyloge...

One of the top species in aquaculture sector, known as striped catfish or Pangasianodon hypophthalmus, is an important and valuable freshwater fish many countries. Due to high demand for this species, their number has declined "threatened" levels. Hence, purpose study analyse genetic variation wild cultured collected from five producers Asian countries; Thailand, Vietnam, Indonesia, India, Phil...

The nucleotide sequences of segments of the cytochrome b gene (351 bp), the tRNA(Pro) gene (49 bp), and the control region (approximately 313 bp) of mitochondrial DNA were obtained from 26 fish representing different populations and species of Melanotaenia and one species of Glossolepis, freshwater rainbow fishes confined to Australia and New Guinea. The purpose was to investigate relative rate...

The present study was carried out to validate the single nucleotide polymorphism (SNP) in mitochondrial gene- cytochrome b oxidase at 14,716 bp (C T transition) position obtained from whole genome sequence data of indigenous cattle breeds Department Animal Genetics and Breeding, Madras Veterinary College, Tamil Nadu. A total 288 animals, viz. Alambadi (16), Bargur (99), Kangayam (54), Pulikulam...

background: angiostrongylus cantonensis is a zoonotic public health concern that causes human severe eosinophilic meningitis in southeast asia and china. as a medically important intermediate host of a. cantonensis , bellamya lithophaga (gastrop-oda: viviparidae) is often confused with other morphologically similar sibling spe-cies of genus bellamya , such as b. aeruginosa and b. purificata in ...

A new genetic variation and potential haplotype of Bactericera cockerelli was identified based on the analysis mitochondrial region Cytochrome Oxidase subunit I two populations from greenhouses in Villa Unión, Durango Saltillo, Coahuila, Mexico. found base 247 a 500 bp amplified mtCOI gene, this change implies substitution an adenine (A) to Guanine (G), mutation detected insects collect their p...
