The Lyb genes were novel members of Y-box gene family containing a conserved cold-shock domain with two RNA binding motifs (RNP-1 and RNP-2). Moreover, phylogenetic analysis revealed that there was only one type of Y-box gene before the emergence of gnathostomata. By contrast, the Y-box gene were divided into three groups, YB1, YB2, and CSDA during evolution of jawed vertebrates.

此外， 从Swiss-Prot下载了经实验验证过的Y-box蛋白序列数据，结合实验克隆得到的Lyb基因所编码的氨基酸序列构建系统发育树，发现Y-box基因在有颌类出现以前只有一种类型，有颌类出现以后， Y-box基因分化成YB1、YB2和CSDA三种类型。

Importantly, recent analyses8 have begun to reveal new relationships between early vertebrates, in which acanthodians and placoderms are scattered among the early divisions of gnathostome evolution; acanthodians, in particular, are cropping up on chondrichthyan and osteichthyan stem groups.

有颌类包括硬骨鱼类以及软骨鱼类。软骨鱼类仅占有颌类物种数的2%，其余98%的有颌类都属于硬骨鱼类。在硬骨鱼类中，大约一半是辐鳍鱼类，剩余的统称肉鳍鱼类。辐鳍鱼类包括从斑马鱼到多鳍鱼的大约2万8千个种。

Hoxall genes from 16 vertebrates were analyzed, containing 10 cloned Hoxall genes mentioned above and 6 Hoxall genes from GenBank, Homo sapiens, Mus musculus, Bos taurus, Polyodon spathula, Heterodontus francisci, and Oryzias latipes, in representatives of the three major gnathostome lineages: cartilaginous fish, ray-finned fish and lobe-finned fish.

克隆的基因与从GenBank中获取的人、小家鼠、黄牛、匙吻白鲟、角虎鲨Hoxa11基因及青鳉Hoxa11a基因进行比较分析，这些动物代表了有颌类的三个谱系：软骨鱼类谱系、辐鳍鱼类谱系(斑马鱼、大黄鱼、花鲈、罗非鱼、红鳍东方鲀、乌鳢、青鳉和匙吻白鲟)和肉鳍鱼类谱系(矛尾鱼、热带爪蟾、绿背树蜥、家鸡、人、小家鼠和黄牛)。

The journal welcomes significant papers related mainly to vertebrates of Holarctic region, and papers of more than regional significance are preferred.

该杂志欢迎关于全北区动物的重要论文和不仅具有地域重要性的论文。

One of the most significant applications of this is found in the evolution of the vertebrates, which was mediated by duplications of the hox gene complex.

在由Hox基因复合体复制介导的脊椎动物的进化中，发现了这一论点的一个最有意义的应用。

Hox gene plays a key role in gastrointestinal tract development and differentiation of vertebrates.

Hox基因在脊椎动物消化道胚胎发育及分化形成中具有重要作用。

Humans,like most vertebrates,have 39 HOX genes organized into four clusters.

人类含有39个HOX基因，形成4个基因簇，分布在4条染色体上。

In addition, baculovirus are noninfectious to vertebrates, and their promoters have been shown to be inactive in mammalian cells. Futhermore, the expression level of some recombinant proteins is up to 1000 mg/L. Finally, recombinant proteins are soluble and antigenically, immunogenically and functionally similar to their authentic counterparts. In this article, we used the transfer vector pBlueBac of AcNPV (Autographa californica Nuclear Polyhedrosis Virus) to construct the recombinant baculovirus AcNPV-GM-CSF by in vivo recombinantion.

本文中，我们首先利用苜蓿夜蛾核型多角体病毒带β-Galactosidase 基因标记的非融合蛋白基因转移载体pBlueBac，通过细胞内同源重组的方式将hGM-CSF基因成功地插入病毒AcNPV的基因组中。hGM-CSF基因编码信号肽和完整的氨基酸序列。hGM-CSF基因在感染重组病毒的草地夜蛾培养细胞Sf9中得到表达，感染后的Sf9细胞培养液能刺激人骨髓细胞在体外形成典型的集落，表达水平可达2.7〓CFU／ml。

This indicates that jawed and jawless vertebrates have developed antigen receptors independently.

综上所述，无颌类和有颌类脊椎动物应用不同的抗原识别系统完成适应性免疫反应。

Paleontologists believe they are the most primitive jawed vertebrates, even predating sharks.

经常被称作&海里的恐龙&的盾皮鱼在古生代统治着海洋长达7千万年，直到3.60亿年前灭绝。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
