choanoflagellate

(redirected from Choanoflagellates)

cho·a·no·mas·ti·gote

(kō'an-ō-mas'tī-gōt),
A term, in the series used to describe developmental stages of the parasitic flagellates, denoting the "barleycorn" form of the flagellate in the genus Crithidia characterized by a collarlike extension surrounding the anterior and through which the single flagellum emerges.
See also: amastigote, epimastigote, promastigote, trypomastigote.
Synonym(s): choanoflagellate, collared flagellate
[G. choanē, a funnel, + mastix, whip]

choanoflagellate

or

collar flagellate

any stalked protozoan that occurs either singly or in branching colonies, possessing a FLAGELLUM surrounded by a cup-like structure into which food particles are wafted by flagellar movement. They are very similar to CHOANOCYTE cells.

"Biologists for decades believed the existing theory was a no-brainer, as sponge choanocytes look so much like single-celled choanoflagellates -- the organism considered to be the closest living relatives of the animals," she said.
How Multi-Celled Animals Developed
Thus, we carefully addressed the fact that we did not find any HcM genes in any other metazoan and choanoflagellates, as expected (Table A1).
Discovery of Novel Hemocyanin-Like Genes in Metazoans
G protein-coupled receptors exist in eukaryotes, including yeast, choanoflagellates, and animals [2].
Identification of Three Novel Splicing Variants and Expression Analysis of Chicken GPR1 Gene
In the new vision--based on increasingly sophisticated genetic analyses--people and other animals are closer cousins to single-celled choanoflagellates than to other multicellular organisms.
Strange relations: schoolroom kingdoms are taking a backseat to life's supergroups
By this means it was revealed that all the flagella and cilia in animals including sponges, Mesozoa and choanoflagellates showed the twoheaded outer arm profile.
Tubulin-dynein system in flagellar and ciliary movement
Choanoflagellates are one-celled eukaryotes that are the closest relatives of animals (Figure 2).
Visualizing proteins & their evolution
Free-living, unicellular organisms called choanoflagellates, however, could be on every person's family tree, so long as it was a gigantic one.

Appendices
These data support the view that all animals are derived from choanoflagellates, but cannot differentiate between single or multiple origins of multicellularity.
The developmental role of the extracellular matrix suggests a monophyletic origin of the kingdom Animalia
Other studies suggest that TRPM, along with TRPA and TRPC, has evolved later in the unikont lineage, as it is present in the genomes of the choanoflagellates Monosiga brevicollis and Salpingosea rosetta, representing the last unicellular ancestor of Metazoa (Mederos y Schnitzler et al., 2007; Cai, 2008; Cai and Clapham, 2012; Peng et al., 2015).
