The paper identifies a novel gene, beer belly, as a regulator of segmentation in spiders using single-cell RNA sequencing and shows its evolutionary loss in mammals and holometabolous insects.

This study shows that polar bodies guide germ disc formation, setting the anteroposterior axis in spiders, and this process is pre-determined and conserved across spider species.

The paper characterizes visual system development in eight spider species to understand how diverse eye configurations arise and evolve.

The paper constructs a single-cell RNA sequencing atlas of spider embryos, revealing cell clusters, gene expression patterns, and developmental insights into arthropod embryogenesis.

This study shows FGF signalling is essential for cumulus migration and dorsoventral axis formation in spider embryos.

The paper analyzes gene and protein domain content changes across 76 arthropod genomes to understand evolutionary patterns and their association with phenotypic adaptations.

This study shows that Fog signaling has multiple roles in epithelial morphogenesis across insects, including mesoderm internalization and gut development in Tribolium.

The paper identifies Pt-Ets4 as a key transcription factor required for cumulus function, dorsoventral axis patterning, and mesoderm-like cell fate induction in spider embryos.

The paper analyzes the house spider genome to identify an ancient whole-genome duplication shared by spiders and scorpions, distinct from horseshoe crab duplications.
