摘要
Hox(homeobox genes)基因是存在于染色体上的一段高度保守序列,其蛋白产物作为转录因子也是高度保守的。这些基因调节胚胎发育,尤其在脊椎动物前-后轴(antero-posterior axis)的发育过程中起着重要作用,并指导脊椎动物的体型形成。海胆是海洋中一类比较常见的无脊椎动物和主要的海水养殖动物,它的Hox基因对它动-植物轴(animal-vegetalaxis)的形成有调控作用,并对进化研究和养殖生产具有重要意义。综述了近年来Hox基因在海胆中的研究进展。
Homeobox genes（Hox genes） are some highly conserved DNA sequences on the chromosomes. The protein products of Hox genes, as transcription factors, are also highly conserved. These genes play a central role in the developmental processes of the anterior-posterior axis of vertebrates by regulating the fetafion, and define body pattern in the vertebrates. Sea urchin is a kind of familiar invertebrate and main aquatic animal. Its Hox genes can regulate and control the form of its animal-vegetal axis, so it is very important for evolution research and production of sea urchin. We have reviewed the latest studies of the Hox genes of sea urchin in this article.
