Recent research has shown that Toll genes, and in particular a newly defined class of Toll genes, the so-called Long Toll Genes (Loto genes), are crucial factors in embryogenesis. In arthropods, they are involved in axis formation via a pro...

There is a growing amount of empirical evidence on the important role of cell size in body size adjustment in ambient or changing conditions. Though the adaptive significance of their correspondence is well understood and demonstrated, the ...
Ontogeny and development of the tritocerebral commissure giant (TCG): an identified neuron in the brain of the grasshopper Schistocerca gregaria [0.03%]
超级大脑半球 Giant（TCG）神经元的胚胎发育及幼虫期形成：超级大脑半球 Giant（TCG）神经元在非洲迁飞 locusta(Schistocerca gregaria)脑中的个体发生及发育

George Stephen Boyan et al.
The tritocerebral commissure giant (TCG) of the grasshopper Schistocerca gregaria is one of the best anatomically and physiologically described arthropod brain neurons. A member of the so-called Ventral Giant cluster of cells, it integrates...
Asymmetric pitx2 expression in medaka epithalamus is regulated by nodal signaling through an intronic enhancer [0.03%]
鱼类Nodal信号通过一种内含子增强子调控皮克斯2基因在上丘中的不对称表达

Vladimir Soukup
The epithalamic region of fishes shows prominent left-right asymmetries that are executed by nodal signaling upstream of the asymmetry-determining transcription factor pitx2. Previous reports have identified that nodal controls the left-sid...

Arthropod early neurogenesis shows distinct patterns that have been interpreted in an evolutionary framework. For instance, crustaceans and Hexapoda form the taxon Tetraconata and share the differentiation of specific neural precursors, the...

About 70% of zebrafish (Danio rerio) genes are orthologues of the human's, which are of great interests, but still largely unknown for their functions. Recently, a report on human histone PARylation factor 1 (HPF1/C4orf27) showed that it is...
Patterns of cell death in the embryonic antenna of the grasshopper Schistocerca gregaria [0.03%]

We have investigated the pattern of apoptosis in the antennal epithelium during embryonic development of the grasshopper Schistocerca gregaria. The molecular labels lachesin and annulin reveal that the antennal epithelium becomes subdivided...
Expression characteristics and functional analysis of Krüppel-like factor 4 in adductor muscle and mantle of Zhikong scallop Chlamys farreri [0.03%]

Insects show relatively little genital variation within species compared to extraordinary and often rapid diversification among species. It has been suggested that selection for reproductive isolation through differences in genital shape mi...
