Here, we identified paralogous tlr22 genes in 13 teleost Duplication fishes by screening available fish genomic resources and using molecular cloning. We then conducted com- Expression pattern prehensive bioinformatics analyses and investigated spatiotemporal differences in the expression patterns of the Gymnocypris eckloni tlr22 genes in G. eckloni. The results indicated that more than three paralogous tlr22 genes were possessed by Teleost fishes some teleost fishes. Of these, tlr22c is specific to some subfamilies of the Cyprinidae (e.g., Barbinae, Cyprininae, Schizothoracinae, and Leuciscinae). Phylogenetic and syntenic analyses showed that the paralogous tlr22 genes originated from two single-gene duplication events. Molecular clock calculations dated the two gene duplication events at 49.5 and 39.3 MYA, which is before the common carp-specific genome duplication event and well after the fish-specific genome duplication. -
From Kunlun Pass Basin, Northeastern Tibetan Plateau and Their Bearings on Development of Water System and Uplift of the Area
SCIENCE CHINA Earth Sciences • RESEARCH PAPER • April 2010 Vol.53 No.4: 485–500 doi: 10.1007/s11430-010-0048-5 Pliocene cyprinids (Cypriniformes, Teleostei) from Kunlun Pass Basin, northeastern Tibetan Plateau and their bearings on development of water system and uplift of the area WANG Ning & CHANG Mee-mann* Key Laboratory of Evolutionary Systematics of Vertebrates, Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, Beijing 100044, China Received November 23, 2009; accepted February 25, 2010 Here described are the cyprinid fossils from the Pliocene Lower Member of Qiangtang Formation of the Kunlun Pass Basin, northeastern Tibetan Plateau, collected at a locality 4769 m above the sea level (asl). The materials consist of numerous disar- ticulated and incomplete bones as well as thousands of pharyngeal teeth, fin rays, and vertebrae. The fossils were referred to the genus Gymnocypris, lineage Schizothoracini, family Cyprinidae; the lineage Schizothoracini; and the family Cyprinidae respectively. The Schizothoracini is a freshwater fish group endemic to the Tibetan Plateau and its surrounding area. Previous workers on living schizothoracins regarded that Gymnocypris belongs to the highly specialized grade of the group, colonizing higher altitudes than other members of the group. Two species are so far unequivocally assigned to the genus, i.e., G. przewalskii and G. eckloni, and they are inhabiting Qinghai Lake and the waters on both north (the Golmud River) and south (upper reach of the Yellow River) sides of the East Kunlun Mountain, respectively. The abundant fossil schizothoracins occur in the Kunlun Pass Basin on the southern slope of the East Kunlun Mountain (at 4769 m asl), close to the present Golmud River, indicating comparatively rich waters in the area and possible connections between the water systems on north and south sides of the East Kunlun Mountain during the Pliocene. -

This is an open-access article distributed under the terms of the Creative Commons Attribution ShareAlike (CC BY-SA) 4.0 License. ABSTRACT. To assess the genetic diversity, structure, and population dynamics of Schizopygopsis pylzovi, we examined the changes in mitochondrial DNA sequences (the mtDNA control region and the Cyt b gene; 1835 bp) in 304 individuals from nine populations. The samples were segregated into 112 haplotypes, with high haplotype diversity and low nucleotide diversity. The haplotype diversity was highest in the Minhe (HS) range of Huangshui River and lowest in the Weiyuan (WY) range of Weihe River. Analysis of molecular variance showed that 69.64% of the total genetic variance was contributed by within-the-group variation and 30.36% was contributed by among-the-group variation. Pairwise FST revealed significant divergence between the populations. The FST Genetics and Molecular Research 15 (3): gmr.15038480 Y.N. Ma et al. -
And Adaptive Evolution in Their Mitochondrial Genomes

Clarifying the evolutionary history of the schizothoracine fish is therefore important for better understanding the biodiversity of the QTP. Although mor- phological and molecular phylogenetic studies have supported the monophyly of the Schizothoracinae, a recent molecular phylogenetic study based on the mito- chondrial genome questioned the monophyly of this taxon. However, the phylo- genetic analysis of that study was on the basis of only three schizothoracine species, and the support values were low. In this report, we inferred the phylo- genetic tree on the basis of mitochondrial genome data including 21 schizothora- cine species and five closely related species, and the polyphyletic origins of the Schizothoracinae were strongly supported. The tree further suggests that the Schizothoracinae consists of two clades, namely the “morphologically specialized clade” and the “morphologically primitive clade”, and that these two clades migrated independently of each other to the QTP and adapted to high altitude. We also detected in their mitochondrial genomes strong signals of posi- tive selection, which probably represent evidence of high-altitude adaptation. -

In order to study the genetic diversity and taxonomic status of Gymnocypris chilianensis on a molecular level, the mitochondrial DNA cytochrome b gene was sequenced for 74 individuals of G. chilianensis from two locations (Heihe River and Shule River) and 42 individuals of its affinis species Gymnocypris przewalskii. Analyses of genetic diversity and sequence differences were conducted for these samples, combined with the analysis of 30 homologous sequences of another affinis species Gymnocypris eckloni, which were downloaded from GenBank. The results showed that both the haplotype diversity (h = 0.9820) and nucleotide diversity (π = 0.0039) of the Shule River G. chilianensis were lower than the other populations, thus, the Shule River G. chilianensis should be prioritized for protection because of its lower genetic diversity level. The results of sequence analysis showed that the genetic distance between the Heihe River G. chilianensis population and the Shule River G. chilianensis population was 0.0064, and the Genetics and Molecular Research 14 (3): 9253-9260 (2015) ©FUNPEC-RP www.funpecrp.com.br J.P. -

Comparison of mitochondrial (control region) variation (42 haplotypes in 203 fish) of G. przewalskii with the postulated ancestral species found in the Yellow River, Gymnocypris eckloni (10 haplotypes in 23 fish), indicated no haplotype sharing, but incomplete lineage sorting. Consistent with the sub-species status, an AMOVA indicated that the Ganzi River population was significantly different from all other river populations (FST = 0·1671, P<0·001). -

Cyprininae phylogeny was analyzed using mitochondrial and nuclear DNA sequences to trace origins of polyploidy and diversifications of schizothoracins. Ancestral states reconstruction for ploidy levels indicated that the Cyprininae was diploid origin and the schizothoracin clades tetraploid origins. There were two diversification rate shifts along with diversification of the cyprinine fishes in response to the Tibetan uplift. The unusual diversification shifts were located to branches subtending the clades of Tibetan polyploid cyprinids. Our analyses suggested that (i) phylogeny of Cyprininae recovered two independent origins of the Tibetan polyploidy schizothoracins; (ii) diversifica- tions of the schizothoracins were closely related to the Neogene uplift -
Cyprinid Phylogeny Based on Bayesian and Maximum Likelihood Analyses of Partitioned Data: Implications for Cyprinidae Systematics

In this study, we used the nuclear recombination activating gene 2 and the mitochondrial 16S ribosomal RNA and cytochrome b genes to reconstruct cyprinid phylogeny. Our aims were to (i) demonstrate the effects of partitioned phylo- genetic analyses on phylogeny reconstruction of cyprinid fishes; (ii) provide new insights into the phylogeny of cyprinids. Our study indicated that unpartitioned strategy was optimal for our analyses; partitioned analyses did not provide better-resolved or -supported estimates of cyprinid phylogeny. Bayesian analyses support the following relationships among the major mono- phyletic groups within Cyprinidae: (Cyprininae, Labeoninae), ((Acheilognathinae, ((Leuciscinae, Tincinae), Gobioninae)), Xenocyprininae). The placement of Danioninae was poorly resolved. Estimates of divergence dates within the family showed that radiation of the major cyprinid groups occurred during the Late Oligocene through the Late Miocene. Our phylogenetic analyses improved our understanding of the evolutionary history of this important fish family.
