To be or not to be a flatworm: the acoel controversy.

PLoS ONE, 2009
Since first described, acoels were considered members of the flatworms (Platyhelminthes). However, no clear synapomorphies among the three large flatworm taxa -- the Catenulida, the Acoelomorpha and the Rhabditophora -- have been characterized to date ...

Compromised DNA replication in gut cells underlies sensitivity to genotoxic stress in the tardigrade Hypsibius exemplaris

The FEBS Journal, EarlyView.
DNA damage in the tardigrade Hypsibius exemplaris elicits distinct cellular outcomes depending on replication status. While non‐replicating cells tolerate genotoxic stress, constitutively replicating cells undergo irreversible replication failure upon DNA damage, leading to loss of tissue homeostasis, fat depletion, sterility, and organismal death ...

No evidence for a culturable bacterial tetrodotoxin producer in Pleurobranchaea maculata (Gastropoda: Pleurobranchidae) and Stylochoplana sp. (Platyhelminthes: Polycladida) [PDF]

, 2015
Tetrodotoxin (TTX) is a potent neurotoxin found in the tissues of many taxonomically diverse organisms. Its origin has been the topic of much debate, with suggestions including endogenous production, acquisition through diet, and symbiotic bacterial ...

Circadian regulation of reproduction and neoblast cell division in the catenulid flatworm Stenostomum virginianum (Platyhelminthes)

Photochemistry and Photobiology, EarlyView.
The circadian clock and melatonin coordinate homeostasis in many animals, yet their influence on reproduction and neoblast proliferation has only been shown in triclads. This study demonstrates that the early‐branching catenulid Stenostomum virginianum contains photoreceptive refractile bodies, synthesizes endogenous melatonin, and that exogenous ...

Outstanding intraindividual genetic diversity in fissiparous planarians (Dugesia, Platyhelminthes) with facultative sex.

, 2019
Predicted genetic consequences of asexuality include high intraindividual genetic diversity (i.e., the Meselson effect) and accumulation of deleterious mutations (i.e., Muller’s Ratchet), among others.

Evolutionary history of the Tricladida and the Platyhelminthes: an up-to-date phylogenetic and systematic account [PDF]

, 2012
Within the free-living platyhelminths, the triclads, or planarians, are the best-known group, largely as a result of long-standing and intensive research on regeneration, pattern formation and Hox gene expression.

Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia

Zoologica Scripta, EarlyView.
ABSTRACT Lophotrochozoa is one of the three major bilaterian groups comprising more than half of the bilaterian phyla. Lophotrochozoa includes among others Mollusca, Annelida, Platyhelminthes and Rotifera. Despite representing such a large proportion of animal diversity, they are historically understudied and genomic resources have been scarce. However,
