When we minimize LBA we find consistent support for a position of both acoelomorphs and Xenoturbella within the deuterostomes. The most likely phylogeny. Xenoturbellida and Acoelomorpha are marine worms with contentious ancestry. Both were originally associated with the flatworms. 筑波大学の研究情報ポータル、COmmunity of Tsukuba Researchers、略して COTREにようこそ!このサイトでは、筑波大学に所属する研究者の情報、筑波大学が 誇る高.

Characterization of the complete mitochondrial genomes from Polycladida Platyhelminthes using next-generation sequencing.

Acoelomorpha Search for deuterosttomes papers on this topic. Gerhard Schlosser 26 Estimated H-index: Fill in your details below or click an icon to log in: Vincent Laudet 64 Estimated H-index: The original radially-distributed nerve cords were simplified in dorsal or ventral ones in higher groups, but remained radial in Acoelomorpha.

Now if you think of them as primitive groups, the only thing necessary is to analyze protostomes as having lost a microRNA sequence. Tweedt 6 Estimated H-index: Xenoturbella is an acoelomorph. Skip to search form Skip to main content.


Acoelomorph flatworms are deuterostomes related to Xenoturbella – Semantic Scholar

Acoelomorpha, Xenoturbellida, Deuterostomiaa and Protostomia. There are two groups of acoelomorphs: Cited Source Add To Collection. The truth is that this sequence is absent in Protostomia, but present in all other groups. Biological Relatedd,DOI: Buckley 14 Estimated H-index: References Publications referenced by this paper.

Several phylogenetic studies indicate that Acoelomorpha is indeed a basal group of bilateral animals.

Phylogenetic position of Acoelomorpha and Xenoturbellida according to Boll et al. Xenoturbella is an acoelomorph! Claus Nielsen 17 Estimated H-index: Joseph Felsenstein 59 Estimated H-index: Xenoturbella is an acoelomorph!

It means that that xfnoturbella sequence is found in deuterostomes, but not in protostomes. We show that analyses of miRNA complements have been affected by character acorlomorph in the acoels and that both groups possess one miRNA and the gene Rsb66 otherwise specific to deuterostomes.

Really interesting post; flatworms are really remarkable. Gonzalo Giribet 59 Estimated H-index: Topics Discussed in This Paper. June 9, at 1: Xenoturbella is a deuterostome that eats molluscs.
