ABSTRACT
Albooshokeh SN, Tahmoorespur M, Nassiry MR., Characterization and Sequencing of MT-COX1
gene from chickens, Onl J Bioinform,
22 (2): ): 52-61, 2021. Two DNA fragments were
amplified, cloned to pTZ57R/T vector and transformed into an E. coli -
DH5α strain. Recombinant plasmids were then extracted from positive
colonies and sequenced. The results of nucleotide sequence indicated maximum of
similarity with the same sequence in the Gallus Gallus
mitochondrial genome reference. Comparing these two sequences identified the presence
of 3 mutations. Amino acid sequences of Khorasan’s native chicken had 99%
similarity in 100% coverage with reference genome and other sequences with
accession numbers YP272100.1, ADB06689.1, AHI87875.1, and YP272087.1. The
protein BLAST query suggested the conserved domain cytochrome C, in a family
which is part of a complex IV. Such mutations may be associated with the
evolution of Khorasan's native chicken to adapt with environmental
circumstances of its place of life.
