Phylogenetic and evolutionary relationships and developmental expression patterns of the zebrafish twist gene family [0.03%]
秀丽隐杆线虫twist基因家族的谱系、进化关系及其发育表达模式

Gare Hoon Yeo et al.
Four members of the twist gene family (twist1a, 1b, 2, and 3) are found in the zebrafish, and they are thought to have arisen through three rounds of gene duplication, two of which occurred prior to the tetrapod-fish split. Phylogenetic ana...
Changes in localization and expression levels of Shroom2 and spectrin contribute to variation in amphibian egg pigmentation patterns [0.03%]
Shroom2和光谱蛋白的定位及表达水平变化对两栖动物卵黄色素模式变异的影响
Chanjae Lee,Minh-Phuong Le,David Cannatella et al.
Chanjae Lee et al.
One contributing factor in the worldwide decline in amphibian populations is thought to be the exposure of eggs to UV light. Enrichment of pigment in the animal hemisphere of eggs laid in the sunlight defends against UV damage, but little i...
Duplication of the Asymmetric Leaves1/Rough Sheath 2/Phantastica (ARP) gene precedes the explosive radiation of the Ruschioideae [0.03%]

We examined the development of the nervous system in the rhopalium, a medusa-specific sensory structure, in Aurelia sp.1 (Cnidaria, Scyphozoa) using confocal microscopy. The rhopalial nervous system appears primarily ectodermal and contains...
Sea urchin arylsulfatase, an extracellular matrix component, is involved in gastrulation during embryogenesis [0.03%]
海胆芳基硫酸酯酶是一种细胞外基质成分，在胚胎发育原肠运动过程中发挥重要作用
Keiko Mitsunaga-Nakatsubo,Yoshihiro Akimoto,Hayato Kawakami et al.
Keiko Mitsunaga-Nakatsubo et al.
Arylsulfatases (Arses) have been regarded as lysosomal enzymes because of their hydrolytic activities on synthetic aromatic substrates and their lysosomal localization of their enzymatic activities. Using sea urchin embryos, we previously d...

Protocadherins constitute the largest subgroup within the cadherin superfamily of cell surface molecules. In this study, we report the molecular cloning and expression analysis of the non-clustered protocadherin-17 (pcdh17) in the embryonic...
Evolutionary modification of specification for the endomesoderm in the direct developing echinoid Peronella japonica: loss of the endomesoderm-inducing signal originating from micromeres [0.03%]
日本帕氏海参内胚层-中胚层分化的演化改良：微胚滋养素的丧失

Minoru Iijima et al.
We investigated the inductive signals originating from the vegetal blastomeres of embryos of the sand dollar Peronella japonica, which is the only direct developing echinoid species that forms micromeres. To investigate the inductive signal...
The involvement of engrailed and wingless during segmentation in the onychophoran Euperipatoides kanangrensis (Peripatopsidae: Onychophora) (Reid 1996) [0.03%]
环节动物门多毛纲南方恐铲甲鳃蜈蚣（Euperipatoides kanangrensis）节段分化的 engrailed 和 wingless 基因的表达模式研究（Reid，1996）
Bo Joakim Eriksson,Noel N Tait,Graham E Budd et al.
Bo Joakim Eriksson et al.
As the putative sister group to the arthropods, onychophorans can provide insight into ancestral developmental mechanisms in the panarthropod clade. Here, we examine the expression during segmentation of orthologues of wingless (Wnt1) and e...
The embryonic development of Schistosoma mansoni eggs: proposal for a new staging system [0.03%]

Schistosomiasis is a water-borne parasitic illness caused by neoophoran trematodes of the genus Schistosoma. Using classical histological techniques and whole-mount preparations, the present work describes the embryonic development of Schis...
Use of freeze-cracking in ontogenetic research in Macrostomum lignano (Macrostomida, Rhabditophora) [0.03%]
