Filasterea
Template:Short description Script error: No such module "Automated taxobox".
Filasterea is a basal Filozoan clade of single-celled ameboid eukaryotes that includes Ministeria and Capsaspora.[1] It is a sister clade to the Choanozoa in which the choanoflagellates and animals appeared, originally proposed by Shalchian-Tabrizi et al. in 2008, based on a phylogenomic analysis with 78 genes. Filasterea was found to be the sister-group to the clade composed of Metazoa and Choanoflagellata within the Opisthokonta, a finding that has been further corroborated with additional, more taxon-rich, phylogenetic analyses.[2][3][4]
Etymology
From Latin filum meaning "thread" and Greek aster meaning "star", it indicates the main morphological features shared by all their integrants: small, rounded amoeboids with a mononucleated cellular body, covered in long and radiating cell protrusions known as filopodia. These filopodia may be involved in substrate adhesion and capture of prey.
Applications
There are currently cultures from two filasterean species: Capsaspora owczarzaki and Ministeria vibrans, the first isolated from within a fresh-water snail, the second a marine, free-living bacteriovore. The complete genome sequences of C. owczarzaki,[5] M. vibrans, Pigoraptor vietnamica and Pigoraptor chileana[6] have been obtained. Comparative analyses have shown that Filasterea are key to unravelling the genetic repertoire of the unicellular ancestor of animals and for providing insights into the origin of Metazoa. Metabarcoding analyses of 18S ribosomal RNA in marine environments have failed to recover other filasterean representatives,[7][8] suggesting this clade may not be especially abundant in natural ecosystems.
