title: Full-length transcriptome of muscle: female Tachypleus tridentatus
design: he horseshoe crab (Tachypleus tridentatus) is valued because of both its ecological and economic importance. However, T. tridentatus has existed in the IUCN Red List of Threatened Species. In recent years, the protection of T. tridentatus has attracted much attention, whole genome sequencing and Illumina RNA-seq were also provide important information resource for the protection of T. tridentatus. However, it is undeniable that the research of evolution, physiological regulation and ecological function has been hampered by gaps in the annotation of the T. tridentatus genome. The third generation sequencing technology provides the opportunity to directly obtain FL transcripts due to this technology accomplishes single molecule real-time sequencing.
