(Submitter supplied) We identified a GATA-like gene named fuchi nashi (fuchi) as a gene required for establishing a germ disc in the early embryo of the spider Parasteatoda tepidariorum. fuchi transcript is initially expressed in cells at both polar regions of the embryo and later in endodermal and extraembryonic cells. To genome-widely identify genes whose expressions are regulated by fuchi, we conducted RNA-sequencing of whole embryos at three different early stages (stages 2 and 3 and early stage 5) that were untreated (control) or treated for fuchi parental RNA interference (pRNAi).

(Submitter supplied) The early embryo of the spider Parasteatoda tepidariorum initially shows spherical symmetry in morphology. Following a symmetry breaking event, it forms a radially symmetric germ disc in the hemisphere of the egg. In this work, we conducted RNA-sequencing of cells isolated from small different regions of radially symmetric forming/formed germ discs, aming to identify candidate genes whose transcripts are locally expressed in early spider embryos.

(Submitter supplied) Hedgehog signaling plays pivotal roles in formation of the embryonic anterior-posterior axis in the spider Parasteatoda tepidariorum. In this work, using the combination of RNA-sequencing and parental RNA interference (pRNAi), we genome-widely identified genes that transcriptionally responded to altered states of Hedgehog signaling in spider embryos, which were caused by Pt-hedgehog (Pt-hh) pRNAi and Pt-patched (Pt-ptc) pRNAi. more...

(Submitter supplied) The common house spider Parasteatoda tepidariorum is a chelicerate model organism for studying developmental mechanisms and their evolution in arthropods. In contrast to the well-studied model insect, Drosophila melanogaster, embryos of the spider undergo patterning in a cellular environment from early stages (at least after the number of the nuclei increase to 16). Use of spider embryos provide new opportunities to understand the evolution of developmental mechanisms underlying arthropod body plans. more...
