AI Article Synopsis

  • The study presents a detailed genome assembly for the orb-weaving spider Uloborus diversus, filling a gap in the genetic research of orb-weaving families that has existed for over 200 million years.
  • This research provides evidence of an ancient genome duplication in arachnids and highlights complete spidroin gene sequences, which are essential for spider silk structure.
  • The findings also identify the sex chromosomes and potential sex-determining genes, making this genome a key resource for studying the evolution of orb-weaving and related genetic traits in spiders.

Article Abstract

The orb web is a remarkable example of animal architecture that is observed in families of spiders that diverged over 200 million years ago. While several genomes exist for araneid orb-weavers, none exist for other orb-weaving families, hampering efforts to investigate the genetic basis of this complex behavior. Here we present a chromosome-level genome assembly for the cribellate orb-weaving spider Uloborus diversus. The assembly reinforces evidence of an ancient arachnid genome duplication and identifies complete open reading frames for every class of spidroin gene, which encode the proteins that are the key structural components of spider silks. We identified the 2 X chromosomes for U. diversus and identify candidate sex-determining loci. This chromosome-level assembly will be a valuable resource for evolutionary research into the origins of orb-weaving, spidroin evolution, chromosomal rearrangement, and chromosomal sex determination in spiders.
