Phylogenetic analysis of NADH dehydrogenase subunit 1(NADH 1) gene in Salmo trutta caspius

Author(s): Abolhasan Rezaei

Abstract: The NADH 1 gene in the Salmo trutta caspius has been sequenced, characterized and deposited in Genbank, Accession Number LC011387. In this study we compared NADH 1 gene between Salmo trutta caspius, Salmo trutta trutta, accession number (AM910409.1), Salmo salar (KF792729.1) and Oncorhynchus mykiss (DQ288268.1) by DNAMAN program and NCBI Network system separately. According to DNAMAN program analysis, we found 23 SNPs and 98% similarity between Salmo trutta caspius and Salmo trutta trutta, 67 SNPs and 92% similarity between Salmo trutta caspius and Salmo salar, 126 SNPs and 86% similarity between Salmo trutta caspius and Oncorhynchus mykiss. Amino acid sequences also were determined by DNAMAN program. Between Salmo trutta caspius and Salmo trutta trutta, 3 SNPs, between Salmo trutta caspius and Salmo salar 14 SNPs, and between Salmo trutta caspius and Oncorhynchus mykiss, 17 SNPs were observed. In this study we concluded that the rate of homology between Salmo trutta trutta and Salmo trutta caspius is more than its homology with Salmo salar and Oncorhynchus mykiss, so these results show that Salmo trutta caspius had originated from Salmo trutta.
