The structure, splicing, synteny and expression of lamprey COE genes and the evolution of the COE gene family in chordates [0.03%]
无颌脊椎动物COE基因的结构、剪接、同线性和表达及脊索动物COE基因家族的演化
Ricardo Lara-Ramírez,Guillaume Poncelet,Cédric Patthey et al.
Ricardo Lara-Ramírez et al.
COE genes encode transcription factors that have been found in all metazoans examined to date. They possess a distinctive domain structure that includes a DNA-binding domain (DBD), an IPT/TIG domain and a helix-loop-helix (HLH) domain. An i...
Conservation of the Notch antagonist Hairless in arthropods: functional analysis of the crustacean Daphnia pulex Hairless gene [0.03%]
节肢动物中Notch拮抗物Hairless的保守性：水溞Hairless基因的功能分析
Ariella Zehender,Melanie Bayer,Milena Bauer et al.
Ariella Zehender et al.
The Notch signaling pathway is highly conserved in all animal metazoa: upon Notch receptor activation, transcription of Notch target genes is turned on by an activator complex that centers on the transcription factor CSL. In the absence of ...
Regulation and function of odd-paired in Tribolium segmentation [0.03%]

The pair-rule gene odd-paired (opa) is required for the patterning of alternate segment boundaries in the early Drosophila embryo. Mutant phenotypes of opa display a typical pair-rule phenotype in which most of each odd-numbered denticle be...

Phenotypic plasticity, the ability of a given genotype to produce different phenotypes in response to distinct environmental conditions, is widely observed in the wild. It is believed to facilitate evolution and, under the "flexible stem hy...
A conserved plan for wiring up the fan-shaped body in the grasshopper and Drosophila [0.03%]
直翅目昆虫扇形体神经元的保守连接模式

George Boyan et al.
The central complex comprises an elaborate system of modular neuropils which mediate spatial orientation and sensory-motor integration in insects such as the grasshopper and Drosophila. The neuroarchitecture of the largest of these modules,...
Modified whole-mount in situ hybridisation and immunohistochemistry protocols without removal of the vitelline membrane in the appendicularian Oikopleura dioica [0.03%]
改良的Oikopleura dioica整体原位杂交和免疫组化方法无需去除卵黄膜

Takeshi A Onuma
The appendicularian Oikopleura dioica is a planktonic chordate that retains a tadpole shape throughout its life. Its simple and transparent body, invariant cell lineages, fast development and available genome and transcriptome resources mak...
Unexpected UBX expression in the maxilliped of the mystacocarid crustacean Derocheilocharis remanei-evidence for a different way of making a maxilliped? [0.03%]
神秘溞属甲壳动物须肢类Derocheilocharis remanei口足部出现意外的UBX表达-一种不同的形成口足的方法？

In terms of morphology, crustacean maxillipeds are hybrid appendages. They arise in anterior thoracic segments and display characteristics of both locomotory (thoracic) and feeding (gnathal) appendages. Maxillipeds are functionally integrat...
Spatiotemporal expression of a twist homolog in the leech Helobdella austinensis [0.03%]
Austin漏斗水蛭(Helobdella austinensi)中Twist同源物的时空表达
Jin-Se Kim,Brenda Irene Medina Jiménez,Hee-Jin Kwak et al.
Jin-Se Kim et al.
Genes of the twist family encode bHLH transcription factors known to be involved in the regulation and differentiation of early mesoderm. Here, we report our characterization of Hau-twist, a twist homolog from the leech Helobdella austinens...

Early embryos of the clitellate annelid Tubifex (oligochaete) undergo a series of unequal spiral cell divisions before the descendants of the D quadrant micromeres (cells 2d and 4d) divide bilaterally. Here, we show that inhibition of zygot...

Identification of molecular markers is an essential step in the study of germ cells. Vasa is an RNA helicase and a well-known germ cell marker that plays a crucial role in germ cell development. Here, we identified the Vasa homolog termed M...
