Multiomics study of a heterotardigrade, Echinisicus testudo, suggests the possibility of convergent evolution of abundant heat-soluble proteins in Tardigrada [PDF]
Background Many limno-terrestrial tardigrades can enter an ametabolic state, known as anhydrobiosis, upon desiccation, in which the animals can withstand extreme environments.

Fibril Structure of Desiccation-Protective Tardigrade Protein CAHS-8. [PDF]
We present the atomic structure of the fibril formed by an intrinsically disordered protein that has been shown to be responsible for remarkable environmental stress in tardigrades. X‐ray crystallography reveals a unique mechanism of fibril assembly whereby a single helix forms a stable, antiparallel coiled‐coil dimer, which then assembles into a ...

A comparative ultrastructure study of the tardigrade Ramazzottius varieornatus in the hydrated state, after desiccation and during the process of rehydration. [PDF]
Tardigrades can survive hostile environments such as desiccation by adopting a state of anhydrobiosis. Numerous tardigrade species have been described thus far, and recent genome and transcriptome analyses revealed that several distinct strategies were ...

Search for putative gene regulatory motifs in CAHS3, linked to anhydrobiosis in a tardigrade Ramazzottius varieornatus, in vivo and in silico. [PDF]
Tardigrades can survive in an almost completely dehydrated state, known as anhydrobiosis, aided by proteins like CAHS3. Research using a newly developed tardigrade‐specific vector revealed that CAHS3 expression is most pronounced in the epidermis, suggesting tissue‐specific regulation rather than uniform expression.

Metabolite phosphatase from anhydrobiotic tardigrades. [PDF]
In this study, we determined the crystal structure of a Ferritin‐like protein widely distributed among intriguing organisms such as tardigrades, which show tolerance to extreme environmental conditions. We identified a dinuclear metal‐binding site, which we found harbors phosphatase activity toward several metabolites, including compounds related to ...

Verification of Hypsibius exemplaris Gąsiorek et al., 2018 (Eutardigrada; Hypsibiidae) application in anhydrobiosis research [PDF]
Anhydrobiosis is considered to be an adaptation of important applicative implications because it enables resistance to the lack of water. The phenomenon is still not well understood at molecular level.

Integrative taxonomy elucidates phylogenetic position of a clawless African eutardigrade (Tardigrada) supporting the erection of a new genus [PDF]
In the presented study, we re-investigated the soil-dwelling clawless tardigrade species Apodibius nuntius (Binda, 1984) using an integrative taxonomic approach.

Three new species of Mesobiotus (Eutardigrada: Macrobiotidae) from Sweden with an updated phylogeny of the genus [PDF]
Three new species of Mesobiotus (Tardigrada: Eutardigrada: Macrobiotidae) are described from Skåne County in the southernmost region of Sweden. All three species are distinguished morphologically and through differences in DNA sequences as supported by ...

The effects of potassium cyanide on tardigrade Paramacrobiotus experimentalis [PDF]
Potassium cyanide (KCN) is a highly lethal poison with cyanide anions having an inhibitory effect on complex IV of the mitochondrial respiratory chain, leading to stoppage in electron transport and eventually cessation of aerobic respiration within the ...
