Decapentaplegic (dpp) regulates the growth of a morphological novelty, beetle horns [0.03%]
蜕变腿足蛋白(dpp)调节甲虫角这一形态新颖性的生长

Bethany R Wasik
Studies focusing on the development of morphological novelties suggest that patterning genes underlying traditional appendage development (i.e. mouthparts, legs, and wings) also play important roles in patterning novel morphological structu...
Knockdown of SPARC leads to decreased cell-cell adhesion and lens cataracts during post-gastrula development in Xenopus laevis [0.03%]
SPARC基因敲低导致非洲爪蟾原肠形成后细胞-细胞粘附降低和晶状体白内障产生
My-Hang Huynh,Shu Jun Zhu,Alexandra Kollara et al.
My-Hang Huynh et al.
SPARC is a multifunctional matricellular glycoprotein with complex, transient tissue distribution during embryonic development. In Xenopus laevis embryos, zygotic activation of SPARC is first detected during late gastrulation, undergoing ra...
Conservation of fruitless' role as master regulator of male courtship behaviour from cockroaches to flies [0.03%]
果蝇果蝇果lessness作为甲虫求偶行为主调控因子的保守性研究至蟑螂
Elke Clynen,Laura Ciudad,Xavier Bellés et al.
Elke Clynen et al.
In Drosophila melanogaster, male courtship behaviour is regulated by the fruitless gene. In D. melanogaster, fruitless encodes a set of putative transcription factors that are sex-specifically spliced. Male-specific variants are necessary a...
Analysis of a botryllid enriched-full-length cDNA library: insight into the evolution of spliced leader trans-splicing in tunicates [0.03%]
(botryllid富集全长)cDNA文库分析：关于尾索动物拼接引导转拼接进化的见解
In some animals, mRNA may be modified after transcription by the addition of a 5' spliced leader sequence. This is known as spliced leader (SL) trans-splicing, and is of uncertain function and evolutionary origin. Here, we report the identi...
Development of an RNA interference method in the cladoceran crustacean Daphnia magna [0.03%]
用枝角类溞建立RNA干扰方法
Yasuhiko Kato,Yasuhiro Shiga,Kaoru Kobayashi et al.
Yasuhiko Kato et al.
Daphnids are small crustaceans ubiquitous in fresh water; they have been a subject of study in ecology, evolution, and environmental sciences for decades. To understand data accumulated in daphnid biology at the molecular level, expressed s...
Expression of the dnmt3 genes in zebrafish development: similarity to Dnmt3a and Dnmt3b [0.03%]
斑马鱼发育过程中dnmt3基因的表达与Dnmt3a和Dnmt3b的关系相似性研究
Tamara H L Smith,Terry Mark Collins,Ross A McGowan
Tamara H L Smith
The zebrafish differs from mammals in that they have six dnmt3 genes as opposed to the two that can produce a catalytically active protein in mammals. Zebrafish also do not show evidence of genomic imprinting and lack the Dnmt3l gene necess...
Patterns of dye coupling involving serotonergic neurons provide insights into the cellular organization of a central complex lineage of the embryonic grasshopper Schistocerca gregaria [0.03%]
涉及血清素能神经元的耦合染料模式为胚胎草地蝈螽Schistocerca gregaria中央复合系神经节细胞组织提供了见解
George Boyan,Bertram Niederleitner
George Boyan
All eight neuroblasts from the pars intercerebralis of one protocerebral hemisphere whose progeny contribute fibers to the central complex in the embryonic brain of the grasshopper Schistocerca gregaria generate serotonergic cells at stereo...
Expression of Distal-less, dachshund, and optomotor blind in Neanthes arenaceodentata (Annelida, Nereididae) does not support homology of appendage-forming mechanisms across the Bilateria [0.03%]
拟步甲属中的Neanthes arenaceodentata（环节动物，Nereididae）的Distal-less、dachshund和optomotor blind的表达不支持二胚层动物肢形成机制的同源性
Christopher J Winchell,Jonathan E Valencia,David K Jacobs
Christopher J Winchell
The similarity in the genetic regulation of arthropod and vertebrate appendage formation has been interpreted as the product of a plesiomorphic gene network that was primitively involved in bilaterian appendage development and co-opted to b...
Rapid evolution of a novel signalling mechanism by concerted duplication and divergence of a BMP ligand and its extracellular modulators [0.03%]
骨形态发生蛋白配体及其细胞外调节因子的协同复制和分化导致新型信号机制的快速进化
Cornelia Fritsch,Robert Lanfear,Robert P Ray
Cornelia Fritsch
Gene duplication and divergence is widely considered to be a fundamental mechanism for generating evolutionary novelties. The Bone Morphogenetic Proteins (BMPs) are a diverse family of signalling molecules found in all metazoan genomes that...
Expansion, diversification, and expression of T-box family genes in Porifera [0.03%]
海绵动物T盒基因家族的扩张、多样化及其表达式式模式分析

Kay Holstien et al.
Sponges are among the earliest diverging lineage within the metazoan phyla. Although their adult morphology is distinctive, at several stages of development, they possess characteristics found in more complex animals. The T-box family of tr...
