چکیده انگلیسی
The bird mitogenome is generally considered to have a conservative genome size, consistent gene content, and similar gene order. As more mitogenomes are sequenced, mitochondrial (mt) gene rearrangements have been frequently identified among diverse birds. Within two genera (Bubo and Strix) of typical owls (Strigidae, Strigiformes), the rearrangement of the mt gene has been a subject of debate. In the current study, we first sequenced the whole mitogenomes of S. uralensis and B. scandiaca and resequenced the entire mitogenome of B. bubo. By combining our data with previously sequenced mitogenomes in Strigidae, we examined the mt gene rearrangements in the family and attempted to reconstruct the evolutionary progression of these rearrangements. The mitogenomes were then used to review the phylogenies of Strigidae. Most mitogenomes exhibited the ancestral gene order (A) in Strigidae. The ancestral gene order in the previously published mitogenome of B. bubo was found to be incorrect. We determined the mt gene order (the duplicate tRNAThr-CR, B) and discovered two additional mt gene orders (the duplicate tRNAGlu-L-CR and CR, C and D) in the Bubo and Strix genera. Gene order B was likely derived from A by a tandem duplication of the region spanning from tRNAThr to CR. The other two modified gene orders, C and D, were likely derived from B by further degenerations or deletions of one copy of specific duplicated genes. We also preliminarily reconstructed the evolutionary progression of mt gene rearrangements and discussed maintenance of the duplicated CR in the genera. Additionally, the phylogenetic trees based on the mitogenomes supported the division of Strigidae into three subfamilies: Ninoxinaeâ¯+â¯(Surniinaeâ¯+â¯Striginae). Within the Striginae clade, the four genera formed a phylogenetic relationship: Otusâ¯+â¯(Asioâ¯+â¯(Buboâ¯+â¯Strix)). This suggests that Otus firstly diverges in their evolutionary history, and Bubo and Strix show a close relationship. B. bubo, B. blakistoni and B. scandiaca form a clade should be considered members of the same genus. The well-supported topology obtained in our Bayesian inference (BI) and maximum likelihood (ML) analyses of Strigid mitogenomes suggests that these genomes are informative for constructing phylogenetic relationships.
