Lineage-specific expansions of the Dicer gene family in tardigrades [PDF]

BMC Genomics
Background RNA interference (RNAi) is an important pathway for gene regulation and immunity. Dicer is a conserved RNAi pathway protein that is found in eukaryotes, with many species expressing multiple dicer gene copies.

Extensive loss of Wnt genes in Tardigrada [PDF]

BMC Ecology and Evolution, 2021
Background Wnt genes code for ligands that activate signaling pathways during development in Metazoa. Through the canonical Wnt (cWnt) signaling pathway, these genes regulate important processes in bilaterian development, such as establishing the ...

Tardigrada of Ireland: a review of records and an updated checklist of species including a new addition to the Irish fauna

ZooKeys, 2016
The phylum Tardigrada was not recorded in Ireland until the Clare Island Survey of 1909–1911, with only rare subsequent reports on Irish tardigrade species. In recent decades, significant taxonomic revision has occurred within Tardigrada.
