Characterization of the complete mitochondrial genome of the king pigeon (Columba livia breed king)

Abstract

The king pigeon is a breed of pigeon developed over many years of selective breeding primarily as a utility breed. In the present work, we report the complete mitochondrial genome sequence of king pigeon for the first time. The total length of the mitogenome was 17,221 bp with the base composition of 30.14% for A, 24.05% for T, 31.82% for C, and 13.99% for G and an A-T (54.22 %)-rich feature was detected. It harbored 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and one non-coding control region (D-loop region). The arrangement of all genes was identical to the typical mitochondrial genomes of pigeon. The complete mitochondrial genome sequence of king pigeon would serve as an important data set of the germplasm resources for further study.

The complete mitochondrial genome of diamond dove (Geopelia cuneata) and its phylogeny

“…Almost all the PCGs use ATN as the initiation codon except for COI starting with GTG. Ten genes (ATP6, ATP8, COI, COII, Cyt b, ND1, ND3, ND4L, ND5, ND6) end with the typical stop codon TAA, TAG, AGA, or AGG, whereas the remaining three genes (COIII, ND2, and ND4) used the incomplete T. The gene arrangement in G. cuneata mitogenome was identical to other Columbidae species (Zhang et al 2015;Huang et al 2016;Soares et al 2016;Bruxaux et al 2018). Phylogenetic analysis of Columbidae species was performed based on the concatenated datasets of 13 PCGs using the maximum-likelihood method in IQ-tree (Nguyen et al 2015).…”
