Acoel flatworms are not platyhelminthes: evidence from phylogenomics. [PDF]

PLoS ONE, 2007
Acoel flatworms are small marine worms traditionally considered to belong to the phylum Platyhelminthes. However, molecular phylogenetic analyses suggest that acoels are not members of Platyhelminthes, but are rather extant members of the earliest ...

Marine flatworms as windows into the evolution of bilaterian neuropeptide signalling. [PDF]

J Neuroendocrinol
Abstract The evolutionary origin(s) of neuropeptide signalling is still largely unknown. It has been hypothesized that signal transmission via neuropeptides played a crucial role in the regulation of nervous systems in the bilaterian ancestor. Identification, expression and functional analyses of neuropeptides and their receptors across different ...

Comparative selenoproteome analysis reveals a reduced utilization of selenium in parasitic platyhelminthes [PDF]

PeerJ, 2013
Background. The selenocysteine(Sec)-containing proteins, selenoproteins, are an important group of proteins present in all three kingdoms of life. Although the selenoproteomes of many organisms have been analyzed, systematic studies on selenoproteins in ...

Riding the Storm: Microeukaryote Community Responses to Hurricane Disturbance. [PDF]

J Eukaryot Microbiol
ABSTRACT Sandy beaches are dynamic ecosystems where terrestrial and marine organisms coexist, resulting in diverse communities where microeukaryotes (protists, microalgae, and meiofauna) are key drivers. Understanding their diversity patterns and responses to stressors is essential for elucidating ecological processes, yet information on this subject ...

A Transcriptomic-Phylogenomic Analysis of the Evolutionary Relationships of Flatworms. [PDF]

, 2015
The interrelationships of the flatworms (phylum Platyhelminthes) are poorly resolved despite decades of morphological and molecular phylogenetic studies [1, 2].
