A novel expression domain of extradenticle underlies the evolutionary developmental origin of the chelicerate patella

The paper identifies a novel expression domain of extradenticle in harvestman patella, suggesting that modification of an ancient gene, not neofunctionalization of a new copy, underlies the origin of the chelicerate patella.

Dual functions of labial resolve the Hox logic of chelicerate head segments

The paper investigates the function of Hox genes lab and Dfd in chelicerates, showing their role in head segment patterning and homeotic transformations through RNAi experiments and expression analysis.

The genome of a daddy-long-legs (Opiliones) illuminates the evolution of arachnid appendages and chelicerate genome architecture

This study presents the genome of a daddy-long-legs and investigates appendage development through functional experiments, revealing conserved and coopted roles of Egfr in leg patterning across arthropods.

How spiders make their eyes: Systemic paralogy and function of retinal determination network homologs in arachnids

The paper investigates the genetic basis of eye development and reduction in arachnids, identifying duplicated RDGN homologs and showing that soA is necessary for eye development across arachnid species.

Genomic resources and toolkits for developmental study of whip spiders (Amblypygi) provide insights into arachnid genome evolution and antenniform leg patterning

This study establishes genomic resources for whip spiders and shows they share a genome duplication with spiders and scorpions, while characterizing the genetic basis of antenniform leg development.
