RNA-Seq data of common woodlice Porcellio scaber
<p>This dataset contains raw transcriptome sequences of common woodlice <em>Porcellio scaber</em> (Crustacea: Isopoda), an important model species in ecotoxicology, developmental biology, immunology and physiology studies. In this context, dataset (transcriptome) provides a cornerstone for all future gene-based research of <em>P. scaber</em>. </p> <p>For transcriptome construction, total RNA was extracted from the whole organism of <em>P. scaber</em>. The extracted RNA was checked for quantity, purity, and integrity and sent to Novogene (United Kingdom) for sequencing. The transcriptome was generated by high-throughput sequencing using an Illumina NovaSeq 6000 platform with 150 bp paired-end option. The dataset contains raw reads recorded in FASTQ format; Ps2_1.fq and Ps2_2.fq, containing Read 1 and Read 2 for paired-end sequencing, respectively.</p>

Figure 5 - A schematic representation showing the ultrastructural characteristics of the hindgut apical matrices and epithelium during late intramarsupial development and in comparison to the hindgut cuticular lining of adult animals in Porcellio scaber. The axis represents the successive developmental stages and the percentage of embryonic development. The vertical dashed lines indicate the transition from embryonic to larval development and from larval development to adult stage. The thick horizontal lines represent presence of the individual feature in the certain stages. The specific features of the cuticle are indicated by the thin lines.
