摘要

摘要 在这篇综述中,我们简要讨论了黑腹果蝇和脊椎动物中参与眼和腿发育的基因。这些动物有许多同源基因,而且这些基因在其发育过程中的相互作用方式与 "深度同源 "的概念以及具有眼睛和四肢的双翅目复杂共同祖先的假说是一致的。线虫基因组包含了控制其他动物眼睛和四肢发育的大部分基因。我们的研究结果表明,线虫类也是如此,尽管这些类群中保存的基因集有所不同:在线虫类中发现了dpp/BMP的直向同源物,而线虫类中只有该基因的旁系亲属。线虫纲和内吸虫纲都缺乏调节其他动物四肢发育的基因 Ss、fng/Rfng 和 Cll 的直向同源物。

Legless and Eyeless Animals

Abstract

In this review, we briefly discuss genes involved in eye and leg development in Drosophila melanogaster and Vertebrates. The fact that these animals have many homologous genes and the ways these genes interact in their development is consistent with the concept of ‘deep homology’ and the hypotheses of a complex common ancestor of Bilateria, which had eyes and limbs. Nematode genomes contain most of the genes, which control eye and limb development in other animals. We show this is also true for Nematomorpha, though the sets of preserved genes are different in these taxa: ortholog of dpp/BMP was found in Nematomorpha, though Nematoda have just a paralogs of this gene. Both Nematoda and Nematomorpha lack orthologs of genes Ss, fng/Rfng, Cll, which regulate limbs development in other animals.

期刊介绍: Paleontological Journal (Paleontologicheskii zhurnal) is the principal Russian periodical in paleontology. The journal publishes original work on the anatomy, morphology, and taxonomy of fossil organisms, as well as their distribution, ecology, and origin. It also publishes studies on the evolution of organisms, ecosystems, and the biosphere and provides invaluable information on global biostratigraphy with an emphasis on Eastern Europe and Asia.
