This study presents the first molecular evidence of Macrovipera razii from central Zagros, more than 300 km north-west of its prior records in southern Iran. Molecular analyses based on mitochondrial cytochrome b sequences identified the individuals from central Zagros as a lineage of M. razii. Specimens from the new localities are separated by a genetic distance of 1.46% from the known populations of M. razii. The results extend the known distribution range of M. razii as an endemic species of Iran.

Pachyhynobius Shangchengensis

Based on morphological and molecular analyses, Xiong et al. (2007) synonymized Hynobius yunanicus Chen et al. with Pachyhynobius shangchengensis Fei et al., both from continental China. Their study, however, was not substantial enough in that morphology of types of neither species was compared, only a partial mitochondrial cytochrome b (cyt b) sequence was employed, and data for H. chinensis was lacking. In order to reassess their conclusion, we morphologically examined type specimens of both species, and compared their complete cyt b (1141 bp) sequences, together with all the six recognized continental Hynobius species and some congeners from Japan and South Korea.

Pcr Products

The identification of fish species in food products is problematic because morphological features of the fish are partially or completely lost during processing. It is important to determine fish origin because of the increasing international seafood trade and because European Community Regulation 104/2000 requires that the products be labeled correctly. Sequence analysis of PCR products from a conserved region of the cytochrome b gene was used to identity fish species belonging to the families Gadidae and Merluccidae in 18 different processed fish products. This method allowed the identification of fish species in all samples. Fish in all of the examined products belonged to these two families, with the exception of one sample of smoked baccalà (salt cod), which was not included in the Gadidae cluster.

Cyt B Gene

The mitochondrial cytochrome b (cyt-b) gene as a phylogenetic marker of lais fish Kryptopterus schilbeides from Kampar River in Riau has been studied. This is a prelimininary research on the utility of cyt-b gene as a molecular marker to obtain species diversity and phylogenetic relationship among Kryptopterus fishes from Kampar River. The primers of L14841 and H15149 were used to amplify the cyt-b gene. The results showed that K. schilbeides has isoleusine at site-81 and metionine at site-114; K. schilbeides from Kampar River and K. schilbeides from GenBank form a phylogeny cluster at 45% value.
