Single-cell transcriptomics reveals the brain evolution of web-building spiders

(Submitter supplied) Spiders are renowned for their efficient capture of flying insects using intricate aerial webs. How the spider nervous systems evolved to cope with this specialized hunting strategy and various environmental clues in an aerial space remains unknown. Here, we report a brain cell atlas of >30,000 single-cell transcriptomes from a web-building spider (Hylyphantes graminicola). Our analysis revealed the preservation of ancestral neuron types in spiders, including the potential coexistence of noradrenergic and octopaminergic neurons, and many peptidergic neuronal types that are lost in insects. more...

Transcriptome changes reveal the toxic mechanism of cadmium and lead combined exposure on silk production and web-weaving behavior of spider A. ventricosus

(Submitter supplied) The goals of this study are to compare NGS-derived transcriptome of ampullate gland and cerebral ganglia under single and combined exposure to cadmium (Cd) and lead (Pb). The upregulated ampullate spidroin genes, downregulated protein anabolic genes, upregulated Far genes, and downregulated TUBA genes exhibit promising potential as biomarkers for silk protein synthesis and cellular degeneration, respectively. more...

Regulation of chromatin accessibility in early embryos of the common house spider Parasteatoda tepidariorum

(Submitter supplied) We identified a lineage-specific GATA-like gene named fuchi nashi (fuchi) as a gene required for establishing a germ disc in the early embryo of the common house spider Parasteatoda tepidariorum. To investigate possible involvement of the early fuchi activity in regulation of chromatin accessibility, we used an assay for transposase-accessible chromatin with high-throughput sequencing (ATAC-seq). Whole embryos at stage 3 that were untreated (wild-type) or treated for fuchi or hedgehog (hh) parental RNAi (pRNAi), as well as wild-type whole embryos at stages 1 and 2, were analyzed by ATAC-seq. more...

Identification of genes whose expression is affected by fuchi nashi pRNAi in early embryos of the spider Parasteatoda tepidariorum

(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).

Genome-wide identification of candidate genes whose transcripts are locally expressed in early embryos of the spider Parasteatoda tepidariorum

(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.

Single-cell and single-nucleus transcriptome analysis of pattern formation in the early embryo of the spider Parasteatoda tepidariorum

(Submitter supplied) In a cellular field of the early spider embryo, Hedgehog signaling operates to specify a “fuzzy” French-flag-like pattern along the primary axis. We applied single-cell and single-nucleus RNA sequencing to the early spider embryo. We confirmed that these techniques successfully detected three cell population corresponding to germ layers and some known cell types. We showed that the data had sufficient information for reconstruction of a correct global polarity of the presumptive ectoderm.

Genome-wide Identification of genes that transcriptionally respond to altered states of Hedgehog signaling in embryos of the spider Parasteatoda tepidariorum

(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...

Identification of genes whose expression is affected by ptc + dpp double RNAi in spider embryos

(Submitter supplied) In the spider Parasteatoda tepidariorum, Hedgehog (Hh) and Decapentaplegic (Dpp) signaling play key roles in the formation of the two major embryonic axes (Akiyama-Oda and Oda, 2010, Development 137, 1263-1273; Akiyama-Oda and Oda, 2006, Development 133, 2347-2357). Patched (Ptc), a receptor for Hh,functions as a negative regulator of Hh signaling. Double parental RNA interference (pRNAi) against spider homologs of ptc and dpp, Pt-ptc and Pt-dpp, respectively, results in severe defects in axis formation. more...

Identification of genes whose expression is affected by Delta RNAi in spider embryos

(Submitter supplied) In the spider Parasteatoda tepidariorum embryo, Delta-Notch signaling plays a key role in early development of the opisthosomal region by regulating the balance between the caudal ectoderm and mesoderm fates (Oda et al., 2007, Development 134, 2195-2205). In this microarray experiment, we attempted to identify candidate genes whose expressions are regulated by Delta-Notch signaling during early phases of the caudal development.

Developmental profiling of gene expression in embryos of the spider Parasteatoda tepidariorum

(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...

Gene expression profiling of multiple tissue types from three species of cobweb weaving spiders

(Submitter supplied) Spider silk synthesis is an emerging model for the evolution of tissue-specific gene expression and the role of gene duplication in functional novelty, but its potential has not been fully realized. Accordingly, we quantified transcript (mRNA) abundance in seven silk gland types and three non-silk gland tissues for three cobweb-weaving spider species. Evolutionary analyses based on expression levels of thousands of homologous transcripts and phylogenetic reconstruction of 605 gene families demonstrated conservation of expression for each gland type among species. more...

Identification of genes whose expression is affected by hedgehog RNAi in spider embryos

(Submitter supplied) In the spider Achaearanea tepidariorum, Hedgehog (Hh) signaling plays a key role in the formation of the two major embryonic axes. Analyses of expression patterns of the spider hh homolog, At-hh, suggested that Hh signaling might be involved in the subsequent segmentation process also. In this microarray experiment, we attempted to identify candidate genes whose expressions are regulated by Hh signaling during early phases of spider segmentation.
