Abstract

Parabramis pekinensis was treated as research object in order to investigate the correlation between morphological traits and body weight. We measured 9 morphological indexes including total length (X₁), body length (X₂), body height (X₃), head length (X₄), snout length (X₅), eye diameter (X₆), eye distance (X₇), caudal stalk length (X₈) and caudal stalk height (X₉). The principal morphological traits affecting body weight were screened out and the regression equation was established. The regression equation of Y1 (age 1 group) shape character (X) and weight (Y) was Y = - 169.183 + 32.544 × ₃ + 10.263 × ₄ + 15.655 × ₇. The regression equation of Y2 (age 2 group) shape character (X) and weight (Y) was Y = - 694.082 + 7.725 × ₁ + 72.822 × ₃ + 77.023 × ₆, the regression equation of Y3 (age 3 group) shape character (X) and weight (Y) was Y = - 1161.512 + 26.062 × ₁ + 22.319 × ₂- 107.218 × ₅ + 83.901 × ₇. Gene expression was consistent with these conclusions. TOR signaling pathway expression raised in Y1 then width increased. And GH-IGF-1 signaling pathway expression raised in Y2 then the length increased. In conclusion, the paper could prove that P. pekinensis showed a growth trend, which was increasing width first and length later. In some sense, the study not only enriched the basic biological data of P. pekinensis, but also provided waiting morphological traits for selective breeding of P. pekinensis artificial breeding in future.

形态性状对不同龄期北京滨鹬体重的影响及生长相关基因分析。

本文以北京仿鹤为研究对象，探讨其形态性状与体重的关系。测定了体长(X1)、体长(X2)、体高(X3)、头长(X4)、口长(X5)、眼径(X6)、眼距(X7)、尾柄长(X8)、尾柄高(X9)等9项形态学指标。筛选了影响体重的主要形态性状，建立了回归方程。Y1(1岁组)体型特征(X)与体重(Y)的回归方程为Y = - 169.183 + 32.544 × 3 + 10.263 × 4 + 15.655 × 7。Y2(2岁组)外形特征(X)与体重(Y)的回归方程为Y = - 694.082 + 7.725 × 1 + 72.822 × 3 + 77.023 × 6, Y3(3岁组)外形特征(X)与体重(Y)的回归方程为Y = - 1161.512 + 26.062 × 1 + 22.319 × 2- 107.218 × 5 + 83.901 × 7。基因表达与这些结论一致。TOR信号通路在Y1中表达升高，宽度增加。GH-IGF-1信号通路在Y2中表达升高，随后长度增加。综上所述，本文可以证明北京猿猴呈现出先宽后长的生长趋势。从某种意义上说，该研究不仅丰富了北京白鲟的基础生物学资料，而且为今后北京白鲟人工育种的选择性选育提供了等待的形态性状。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
