India possesses a total buffalo population of 105 million out of which 26.1% inhabit Uttar Pradesh. The buffalo of Uttar Pradesh are described as nondescript or local buffaloes. Currently, there is no report about the genetic diversity, phylogenetic relationship and matrilineal genetic structure of these buffaloes. To determine the origin and genetic diversity of UP buffaloes, we sequenced and analysed the mitochondrial DNA D-loop sequences in 259 samples from entire Uttar Pradesh. One hundred nine haplotypes were identified in UP buffaloes that were defined by 96 polymorphic sites. We implemented neutrality tests to assess signatures of recent historical demographic events like Tajima's D test and Fu's Fs test. The phylogenetic studies revealed that there was no geographic differentiation and UP buffaloes had a single maternal lineage while buffaloes of Eastern UP were distinctive from rest of the UP buffaloes.

Phylogenetic analyses were conducted to evaluate relationships of 5 taxa of Korean Hydrocotyle, H. spp. found in the Ulleung island including one outgroup (Centella asiatica). The molecular phylogenetic methods based on nuclear ribosomal DNA ITS region and cpDNA trnH-psbA region. Centella asiatica was used outgroup for analysis. As the result, genus Korean Hydrocotyle were grouped by 94% bootstrap value. Korean Hydrocotyle was grouped by four clades; Clade I-H. maritima, H. sibthorpides and H. yabei clade Clade II-H. nepalensis clade clade III-H. ramiflora clade clade IV-H. spp. clade. H. maritima, H. sibthorpides and H. yabei was not distinguished, seperately. H. spp. was distinctly distinguished other Korean Hydrocotyle.

Partial mitochondrial 16S rDNA and COI gene were amplified using PCR and sequenced for four species of oysters in Korea. Phylogenetic relationships among them were inferred from their aligned sequences by neighbor-joining method. The sequence comparison data of two mitochondrial genes showed that the genetic distinction between two oyster genera (Crassostreo and Ostrea) was obvious. Phylogenetic analysis based on the nucleotide sequences and A+T percentage of two genes indicates that C. gigas and C. nippona strongly formed a sister group and then C. ariakensis was clustered with the clade although that based on amino acid sequences of COI gene by neighbor-joining method represented different phylogenetic tree.

Sequence data of Cytochrome Oxidase Subunit I (COI) gene of mitochondria were used to elucidate the taxonomy and phylogenetic relationships of the terrestrial planarian taxa in Korea. Published COI gene sequences from Family Bipaliidae in GenBank were also included in the phylogenetic analysis. The aligned data sets for Terricola ranged from 387 to 444 nucleotides (bp) as a result of differences in insert nucleotides. The phylogeny based on COI analysis was not congruenced with the morphological traits. Bipalium nobile included the remainder taxa (Bipalium adventitium, Bipalium venosum, Bipalium kewense, and Bipalium multilineatum). Internal nodes were strongly supported (>91%). The phylogenetic tree on COI analysis showed that most identified species were well separated from each other. The main phylogenetic analysis formed monophyletic groups. COI gene of mitochondria could have the resolving power for taxonomy information for the terrestrial planarian taxa in Korea.
