Dynamic changes in the association between maternal mRNAs and endoplasmic reticulum during ascidian early embryogenesis Dev. Genes Evol. (IF 2.4) Pub Date : 2021-12-18 Toshiyuki Goto, Shuhei Torii, Aoi Kondo, Junji Kawakami, Haruka Yagi, Masato Suekane, Yosky Kataoka, Takahito Nishikata
Axis formation is one of the most important events occurring at the beginning of animal development. In the ascidian egg, the antero-posterior axis is established at this time owing to a dynamic cytoplasmic movement called cytoplasmic and cortical reorganisation. During this movement, mitochondria, endoplasmic reticulum (ER), and maternal mRNAs (postplasmic/PEM RNAs) are translocated to the future

six3 acts upstream of foxQ2 in labrum and neural development in the spider Parasteatoda tepidariorum. Dev. Genes Evol. (IF 2.4) Pub Date : 2020-02-10 Magdalena Ines Schacht,Christoph Schomburg,Gregor Bucher
Anterior patterning in animals is based on a gene regulatory network, which comprises highly conserved transcription factors like six3, pax6 and otx. More recently, foxQ2 was found to be an ancestral component of this network but its regulatory interactions showed evolutionary differences. In most animals, foxQ2 is a downstream target of six3 and knockdown leads to mild or no epidermal phenotypes.
