Complete mitochondrial genome of two shorebirds (Charadriiformes: Scolopacidae), great knot ( Calidris tenuirostris) and bar-tailed godwit ( Limosa lapponica)

Mitochondrial DNA B Resour. 2020 Oct 6;5(3):3516-3518. doi: 10.1080/23802359.2020.1750976.


The mitochondrial genome of Calidris tenuirostris and Limosa lapponica were described using the whole mitochondrial genome obtained from Illumina Next-Generation Sequencing (NGS) technology. Total length of the mitogenome of C. tenuirostris was 16,732bp with slight A+T bias (55.3%). Genome size of L. lapponica was 16,773bp long and A+T biased (56.3%). Both gemones consisting of 2 rRNAs, 13 protein-coding genes, 22 tRNA genes and 1 non-coding regions. This is the first report of complete mitogenomes of these two shorebird species, (C. tenuirostris and of L. lapponica). We observed paraphyletic relationship among the species in the Family Scolopacidae. Also our result showed analogous patterns with the previous studies on the parallel relationships of shorebird species. This study provides basic genetic information for help in understanding phylogenetic relationships . within the Charadriiformes.
