Pioneer neurons of the antennal nervous system project to protocerebral pioneers in the grasshopper Schistocerca gregaria [0.03%]
非洲迁徙蝗虫Schistocerca gregaria触角神经元的先驱神经元向原脑连续投射

George Boyan
The twin nerve tracts of the antenna of the grasshopper Schistocerca gregaria are established early in embryogenesis by sibling pairs of pioneers which delaminate from the epithelium into the lumen at the antennal tip. These cells can be un...
Diversification of four human HOX gene clusters by step-wise evolution rather than ancient whole-genome duplications [0.03%]
四个HOX基因簇的多样化是逐步进化的结果而非古老的全基因组复制产生的结果

HOX genes encode transcriptional factors that play a pivotal role in specifying regional identity in nearly every bilateral animal. The birth of HOX gene cluster and its subsequent evolution, either in regulation or function, underlie the e...
Alterations in Mc1r gene expression are associated with regressive pigmentation in Astyanax cavefish [0.03%]
色素细胞中Mc1r基因表达的变化与Astyanax洞穴鱼的色素消退有关
Bethany A Stahl,Joshua B Gross
Bethany A Stahl
Diverse changes in coloration across distant taxa are mediated through alterations in certain highly conserved pigmentation genes. Among these genes, Mc1r is a frequent target for mutation, and many documented alterations involve coding seq...
Unraveling the evolution and regulation of the alternative oxidase gene family in plants [0.03%]
植物辅氧酶基因家族的进化和调控机制解析
Xiao-jun Pu,Xin Lv,Hong-hui Lin
Xiao-jun Pu
Alternative oxidase (AOX) is a diiron carboxylate protein present in all plants examined to date that couples the oxidation of ubiquinol with the reduction of oxygen to water. The predominant structure of AOX genes is four exons interrupted...
Molecular phylogeny of four homeobox genes from the purple sea star Pisaster ochraceus [0.03%]
紫色海星Pisaster ochraceus的四个同源框基因的分子谱系关系
Giorgio Matassi,Janice Hitomi Imai,Anna Di Gregorio
Giorgio Matassi
Homeobox genes cloned from the purple sea star Pisaster ochraceus (Phylum Echinodermata/Class Asteroidea) were used along with related sequences available from members of other representative animal phyla to generate molecular phylogenies f...
Sequence and expression variation in SUPPRESSOR of OVEREXPRESSION of CONSTANS 1 (SOC1): homeolog evolution in Indian Brassicas [0.03%]
印度甘蓝型 Brassica 中SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1（SOC1）的序列和表达变异：同源渐变式进化

Whole genome sequence analyses allow unravelling such evolutionary consequences of meso-triplication event in Brassicaceae (∼14-20 million years ago (MYA)) as differential gene fractionation and diversification in homeologous sub-genomes. ...
Drosophila Shep and C. elegans SUP-26 are RNA-binding proteins that play diverse roles in nervous system development [0.03%]
Shep(SUP-26)是RNA结合蛋白，在神经系统的发育过程中发挥多样性的功能
Logan T Schachtner,Ismail E Sola,Daniel Forand et al.
Logan T Schachtner et al.
The Caenorhabditis elegans gene sup-26 encodes a well-conserved RNA-recognition motif-containing RNA-binding protein (RBP) that functions in dendrite morphogenesis of the PVD sensory neuron. The Drosophila ortholog of sup-26, alan shepard (...
Patterning of anteroposterior body axis displayed in the expression of Hox genes in sea cucumber Apostichopus japonicus [0.03%]
海参Hox基因表达及其在前后轴模式形成中的作用研究

Mani Kikuchi et al.
The presence of an anteroposterior body axis is a fundamental feature of bilateria. Within this group, echinoderms have secondarily evolved pentameral symmetric body plans. Although all echinoderms present bilaterally symmetric larval stage...
Expression of engrailed-family genes in the jumping bristletail and discussion on the primitive pattern of insect segmentation [0.03%]
弹尾昆虫扰尾叶䗛中同源异形基因的表达及其节段模式的演化探讨

It has been shown that segmentation in the short-germ insects proceeds by a two-step mechanism. The anterior region is simultaneously segmented in a manner similar to that in Drosophila, which is apparently unique to insects, and the rest o...
Evolutionary pathway of pseudogenization of globin genes, α5 and β5, in genus Oryzias [0.03%]
稻属鱼类α5和β5血红蛋白假基因化的进化路径研究

Hemoglobin transports oxygen in many organisms and consists of α- and β-globin chains. Previously, using molecular phylogenetic analysis, we proposed that both α- and β-globins of teleost could be classified into four groups. We also sh...
