Recent advances in both next-generation sequencing and assembly programmes have made the low-cost construction of transcriptome datasets for non-model species feasible, capable of yielding a raft of information even from less well-transcrib...
Early development of coelomic structures in an echinoderm larva and a similarity with coelomic structures in a chordate embryo [0.03%]

Early coelomic development in the abbreviated development of the sea urchin Holopneustes purpurescens is described and then used in a comparison with coelomic development in chordate embryos to support homology between a single arm of the f...
Snail-dependent repression of the RhoGEF pebble is required for gastrulation consistency in Drosophila melanogaster [0.03%]
蜗牛依赖的RhoGEF pebble抑制作用对于果蝇胚胎原肠运动的一致性是必需的

Michael J Murray et al.
The Rho GTP exchange factor, Pebble (Pbl), long recognised as an essential activator of Rho during cytokinesis, also regulates mesoderm migration at gastrulation. Like other cell cycle components, pbl expression patterns broadly correlate w...
A holomorph approach to xiphosuran evolution--a case study on the ontogeny of Euproops [0.03%]
柄足类演化中的自同构群方法——Euproops的个体发育一例研究

Carolin Haug et al.
Specimens of Euproops sp. (Xiphosura, Chelicerata) from the Carboniferous Piesberg quarry near Osnabrück, Germany, represent a relatively complete growth series of 10 stages. Based on this growth sequence, morphological changes throughout ...
Segment polarity gene expression in a myriapod reveals conserved and diverged aspects of early head patterning in arthropods [0.03%]

Arthropods show two kinds of developmental mode. In the so-called long germ developmental mode (as exemplified by the fly Drosophila), all segments are formed almost simultaneously from a preexisting field of cells. In contrast, in the so-c...

Partitioning-defective (par) genes were originally identified as genes that are essential for the asymmetric division of the Caenorhabditis elegans zygote. Studies have since revealed that the gene products are part of an evolutionarily con...

Insect gene function has mainly been studied in the fruit fly Drosophila melanogaster because in this species many techniques and resources are available for gene knock down and the ectopic activation of gene function. However, in order to ...
Injury-induced asymmetric cell death as a driving force for head regeneration in Hydra [0.03%]

The freshwater Hydra polyp provides a unique model system to decipher the mechanisms underlying adult regeneration. Indeed, a single cut initiates two distinct regenerative processes, foot regeneration on one side and head regeneration on t...
Sexually dimorphic expression of foxl2 during gametogenesis in scallop Chlamys farreri, conserved with vertebrates [0.03%]
栉孔扇贝生殖细胞发生过程中foxl2的性别二态表达及其与脊椎动物的保守性研究
Xiao-Ling Liu,Zhi-Feng Zhang,Ming-Yu Shao et al.
Xiao-Ling Liu et al.
FOXL2 is a member of the forkhead box family, a transcription factor essential for the early regulation of ovarian development that is expressed in a sexually dimorphic manner in vertebrates. However, data on this gene in invertebrates are ...

The transition from aquatic to terrestrial life presented tetrapodamorphs with the challenge of maintaining water homeostasis and preventing desiccation on land. The colon evolved in terrestrial vertebrates to help maintain fluid balance. A...
