| barcoding tetrahymena: discriminating species and identifying unknowns using the cytochrome c oxidase subunit i (cox-1) barcode. | dna barcoding using the mitochondrial cytochromecoxidase subunit i (cox-1) gene has recently gained popularity as a tool for species identification of a variety of taxa. the primary objective of our research was to explore the efficacy of using cox-1 barcoding for species identification within the genustetrahymena. we first increased intraspecific sampling fortetrahymena canadensis, tetrahymena hegewischi, tetrahymena pyriformis, tetrahymena rostrata, tetrahymena thermophila, and tetrahymena tro ... | 2011 | 20708435 |
