Mitogenome phylogeny
Brand new mitochondrial succession is actually a widely used molecular ong dogs thirty-five . In today’s investigation, to help expand clarify the latest phylogenetic interrelationships within Anatidae, concatenated nucleotide sequences regarding 13 PCGs as well as 2 rRNA genes was in fact taken from 37 Anatidae aves, regarding five Aythya types, that Netta species, you to Asarcornis kinds, you to Mareca kinds, eight Anas variety, three Mergus types, one Lophodytes types, three Bucephala kinds, one Cairina varieties, one Aix species, two Tadorna species, four Cygnus varieties, you to Branta varieties, four Anser kinds, and something Dendrocygna variety.
Both in the latest Bayesian inference (BI) and limitation possibilities (ML) analyses, the fresh new phylogenetic trees had almost similar topologies (Fig. 7, Supplementary Figs. step one and you will 2). Each other woods about several analyses have been backed by a good statistical beliefs. Generally speaking, the brand new genera Aythya, Netta, Asarcornis, Anas, Mareca, Mergus, Lophodytes, Bucephala, Cairina, Tadorna, and Aix clustered into the subfamily Anatinae, while the subfamily Anserinae got a sis reference to Anatinae, and additionally Cygnus, Branta, and you may Anser. Dendrocygna javanica, whose vertical position, elongated neck and you will base, and you will obvious perching-forest routine identify they away from other Anseriformes species, diverged earlier about fundamental ancestry and you may is short for a sibling clade in order to Anatinae-Anserinae 36 . The topology try extremely consistent with the outcome of studies based to the study regarding concatenated mitochondrial nucleotide sequences off ND2 and you will Cytb genetics, also which have morphological data 36,37,38 .
Unit phylogenetic research away from 37 Anatidae kinds created from the MrBayes and you will IQ forest. Numbers next to the nodes depict posterior odds (left) and you can bootstrap opinions (right).
In this Anserinae, types of the latest genus Anser was related to Branta canadensis closely. This is exactly in line with past morphology-mainly based analyses 39 . The issue is much more cutting-edge into big subfamily Anatinae. Contained in this subfamily, i located four consistent clades: Aythyini (Aythya + Netta + Asarcornis), Anatini (Anas + Mareca), Mergini (Mergus + Lophodytes + Bucephala), and you will Cairinini (Cairina + Aix + Tadorna). Cairinini is actually the new aunt selection of any other Anatinae tribes, that was strongly supported by the outcomes of one’s establish data. From the Anatinae people, Anatini and you will Aythyini enjoys better phylogenetic relationships, and they results are supported by morphological degree and you will phylogenetic research considering two PCGs 37,38 . During the genus Aythya, An effective. americana and you can A. ferina have been clustered in addition to better-supported opinions. At the same time, A beneficial. fuligula together with clade (A beneficial. americana + An excellent. ferina) designed a top-served worthy of branch. Our very own address types, Good. baeri, additionally the clade (A good. fuligula + (A good. americana + A good. ferina)) were clustered with the you to definitely department, indicating the fresh new four variety function an excellent monophyletic category.
Conclusions
The modern study offered the mitogenome off Good. baeri (sixteen,623 bp, accession amount MT129533). So it round mtDNA provided thirteen PCGs, two rRNAs, twenty two tRNAs, and another CR. Thanks to review, it was discovered that the fresh new genome away from An excellent. baeri displayed attribute sequence formations and you can try quite much like the individuals regarding Aythya aves. Among PCGs, ND3 had the most polymorphism and you will large hereditary range. Our phylogenetic research based on combined mitochondrial gene lay (thirteen PCGs as well as 2 rRNAs) away from 37 Anatidae variety using BI and ML algorithms showed that A beneficial. baeri are closely pertaining to An excellent. fuligula, Good. americana, and you will Good. hiki coupons ferina. Indeed, i deduced these particular varieties was basically monophyletic. More over, all genera where multiple species was analyzed was in addition to discovered to be monophyletic with the exception of Anas, just like the you to included Mareca. Today’s studies will bring an essential resource to your conservation out-of the newest examined vitally threatened species along with valuable information to own subsequent phylogenetic and you will evolutionary lookup towards the family members Anatidae.
