The RNA-binding protein Lark has an essential maternal role during Drosophila oogenesis. Elimination of maternal expression results in defects in cytoplasmic dumping and actin cytoskeletal organization in nurse cells. The function of this p...

Indirect development via a feeding pluteus larva represents the ancestral mode of sea urchin development. However, some sea urchin species exhibit a derived form of development, called direct development, in which features of the feeding la...
Expression of somite segmentation genes in amphioxus: a clock without a wavefront? [0.03%]
无头类尾索动物体节分段基因的表达：一种没有波前的时钟模型？

In the basal chordate amphioxus (Branchiostoma), somites extend the full length of the body. The anteriormost somites segment during the gastrula and neurula stages from dorsolateral grooves of the archenteron. The remaining ones pinch off,...
Lamprey snail highlights conserved and novel patterning roles in vertebrate embryos [0.03%]

snail genes mark presumptive mesoderm across bilaterian animals. In gnathostome vertebrates, snail genes are a multimember family that are also markers of premigratory neural crest (pnc) and some postmigratory neural crest derivatives in th...
Relocations of cell convergence sites and formation of pharyngula-like shapes in mechanically relaxed Xenopus embryos [0.03%]

Influence of the relaxation of mechanical tensions upon collective cell movements, shape formation, and expression patterns of tissue-specific genes has been studied in Xenopus laevis embryos. We show that the local relaxation of tensile st...

We investigated the development of Aurelia (Cnidaria, Scyphozoa) during embryogenesis and metamorphosis into a polyp, using antibody markers combined with confocal and transmission electron microscopy. Early embryos form actively proliferat...
Early development, pattern, and reorganization of the planula nervous system in Aurelia (Cnidaria, Scyphozoa) [0.03%]

We examined the development of the nervous system in Aurelia (Cnidaria, Scyphozoa) from the early planula to the polyp stage using confocal and transmission electron microscopy. Fluorescently labeled anti-FMRFamide, antitaurine, and antityr...
Evidence for stasis and not genetic piracy in developmental expression patterns of Branchiostoma lanceolatum and Branchiostoma floridae, two amphioxus species that have evolved independently over the course of 200 Myr [0.03%]
两种独立进化了2亿年的无颌类动物Branchiostoma lanceolatum和Branchiostoma floridae的发育表达模式支持保守而不支持基因剽窃的证据

Ildiko Somorjai et al.
Cephalochordates, the most basal extant group in the phylum Chordata, are represented chiefly by about 20 species of the genus Branchiostoma, commonly called amphioxus or lancelets. In recent years, insights into the evolutionary origin of ...
Conservation of linkage and evolution of developmental function within the Tbx2/3/4/5 subfamily of T-box genes: implications for the origin of vertebrate limbs [0.03%]
T盒基因Tbx2/3/4/5亚家族发育功能的进化及连锁关系的保守性：对脊椎动物肢体起源的启示
Amy C Horton,Navin R Mahadevan,Carolina Minguillon et al.
Amy C Horton et al.
T-box genes encode a family of DNA-binding transcription factors implicated in numerous developmental processes in all metazoans. The Tbx2/3/4/5 subfamily genes are especially interesting because of their key roles in the evolution of verte...
