Connective tissue growth factor (CTGF) plays an important role in regulation of cell growth,differentiation,apoptosis and individual development in animals. The study of sequences variation and molecular evolution of CTGF gene across various species of the cyprinid could be helpful for understanding of speciation and gene divergence in this kind of fish. In this study,19 novel sequences of CTGF gene were obtained from the representative species of the family cyprinidae using PCR amplification,cloning and sequencing. Phylogenetic relationships of cyprinidae were reconstructed by neighbor-joining (NJ),maximum parsimony (MP),maximum likelihood (ML) and Bayesian method. Oryzias latipes from the family Cyprinodontidae was assigned to be the outgroup taxon. Leuciscini and Barbini were clustered into the monophyletic lineages,respectively,with the high nodal supports. The estimation of the ratio of non-synonymous to synonymous substitution (dN/dS) for the various branches indicated that there stood the different evolution rates between the Leuciscini and the Barbini. With the ratio of dN/dS of the Leuciscini being lower than that of the Barbini,species within the Barbini were demonstrated to be subjected to the relatively less selection pressure and under the relaxable evolution background. A 6 bp indel (insertion/deletion) was found at the 50 end of CTGF gene of cyprinidae,and this 6 bp deletion only appeared in the Leuciscini,which is a typical characteristic of the Leuciscini and provides evidence for the monophylogeny of the Leuciscini. For the amino acid sequences of CTGF protein,the most variations and indels were distributed in the signal region and IGFBP region of this protein,implying that these variations were correlated with the regulation of the CTGF gene expression and protein activity.

Molecular variation and evolution of the tyrosine kinase domains of insulin receptor IRa and IRb genes in cyprinidae

Science China(Life Sciences) 2011年第7期54卷 626-633页

作者： KONG XiangHui WANG XuZhen HE ShunPing College of Life Science Henan Normal University Xinxiang 453007 China Institute of Hydrobiology Chinese Academy of Sciences Wuhan 430072 China

The insulin receptor （IR） gene plays an important role in regulating cell growth, differentiation and development. In the present study, DNA sequences of insulin receptor genes, IRa and IRb, were amplified and sequenced from 37 representative species of the cyprinidae and from five outgroup species from non-cyprinid Cypriniformes. Based on coding sequences （CDS） of tyro- sine kinase regions of IRa and IRb, molecular evolution and phylogenetic relationships were analyzed to better understand the characteristics of IR gene divergence in the family cyprinidae. 1Ra and IRb were clustered into one lineage in the gene tree of the IR gene family, reconstructed using the unweighted pair group method with arithmetic mean （UPGMA）. IRa and IRb have evolved into distinct genes after IR gene duplication in cyprinidae. For each gene, molecular evolution analyses showed that there was no significant difference among different groups in the reconstructed maximum parsimony （MP） tree of cyprinidae; IRa and 1Rb have been subjected to similar evolutionary pressure among different lineages. Although the amino acid sequences of IRa and IRb tyrosine kinase regions were highly conserved, our analyses showed that there were clear sequence variations between the tyrosine kinase regions of IRa and IRb proteins. This indicates that IRa and IRb proteins might play different roles in the insulin signaling pathway.

Cyprinid phylogeny based on Bayesian and maximum likelihood analyses of partitioned data:implications for cyprinidae systematics

Science China(Life Sciences) 2012年第9期55卷 761-773页

cyprinidae is the biggest family of freshwater fish, but the phylogenetic relationships among its higher-level taxa are not yet fully resolved. 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））, Xenocyprirlinae）. 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.

A new barbine cyprinid fish, Acrossocheilus multistriatus sp. nov., is described from the Zhujiang River （Pearl River） basin in South China. It is separated from all other barred congeners except A. monticola by its unique coloration pattern of 8-12 vs. 5-7 vertical dark bars on the dorsum and flank. Although 8 vertical black bars are also present in specimens ofA. monticola, the new species is distinct from it by having a well-developed （vs. poor-developed） lower lip, with or without a median interruption （vs. with a median interruption which wider than 1/2 mouth width） on lower jaw, the lower jaw entirely covered （vs. uncoverd） by the lower lip, body depth 22.57%-25.22% SL （vs. 25.64%-32.26% SL）. Additional characteristices as follows： last simple dorsal-fin ray soft without serration; dark stripes on membranes between dorsal-fin rays; dark stripes absent on membranes between anal fin rays; maxillary barbels longer than eye diameter, extending to posterior edge of eyes.

Sequence analysis of cytochrome b gene indicates that East Asian group of cyprinid subfamily Leuciscinae (Teleostei: cyprinidae) evolved independently

Progress in Natural Science:Materials International 2004年第2期 36-41页

The sequences of mitochondrial cytochrome b gene of cyprinid subfamily Leuciscinae are analyzed. Phylogenetic trees generated with methods of neighbor-joining, maximum likelihood and maximum parsimony with Phenacogrammus as an outgroup indicate that Leuciscinae is not a monophyletic group but includes two discrete subgroups. The East Asian group of the subfamily Leuciscinae, including the genera Ctenopharyngodon, Elopichthys, Luciobrama, Mylopharyngodon, Ochetobius , and Squaliobarbus , is close to Aristichthys and Hypophthalmichthys , and they form a monophyletic group which is distant from the leuciscine genera in Europe, Siberia and North America, such as Phoxinus, Leuciscus, Abramis, Rutilus, Chondrostoma, Alburnus, Opsopoedus, Lythrurus , and Pimephales . Our study suggests that the diversified East Asian group of the subfamily Leuciscinae should have an independent origination.

1140 bp of cytochrome b gene were amplified and sequenced from 14 species of primitive cyprinid fishes in East Asia. Aligned with other ten cytochrome b gene sequences of cyprinid fish from Europe and North America retrieved from Gene bank, we obtained a matrix of 24 DNA sequences. A cladogram was generated by the method of Maximum likelihood for the primitive cyprinid fishes. The result indicated that subfamily Leuciscinae and Danioninae do not form a monophyletic group. In the subfamily Danioninae, Opsariichthys biden and Zacco platypus are very primitive and form a natural group and located at the root. But the genera in subfamily Danioninae are included in different groups and have not direct relationship. Among them, Aphyocypris chinensis and Yaoshanicus arcus form a monophyletic group. Tanichthys albonubes and Gobiocypris rarus have a close relation to Gobioninae. The genus Danio is far from other genera in Danioninae. In our cladogram, the genera in Leuciscinae were divided into two groups that
