The Tubulinea are a major grouping of Amoebozoa, including most of the more familiar amoebae genera like Amoeba, Arcella, Difflugia and Hartmannella.

Aug 1, 2017 · Molecular phylogenetic evidence indicates that Amoebozoans are monophyletic, with most, but not all, lobose amoebae falling into one of two subclades: Tubulinea (which includes the lobose testate amoebae or Arcellinida) and Discosea.

Jul 21, 2018 · Also, the name Tubulinea refers to one of the characteristic features of this group, the production of tubular rather than flattened pseudopodia, with cytoplasmic flow within the pseudopodia or entire cell along a single axis. All Tubulinea lack cilia at all stages of the life cycle.

The Tubulinea share the ability to adopt a monopodial locomotive form with monoaxial cytoplasmic flow. The taxon also includes the arcellinids, the only lobose amoebae to form tests, which they construct from organic material.

We recovered a well-resolved and supported tree of Amoebozoa, revealing novel deep level relationships and resolving placement of enigmatic lineages congruent with morphological data. In our analysis the deepest branching group is Tubulinea. A recent proposed major clade Tevosa, uniting Evosea and Tubulinea, is not supported.

May 1, 2013 · Tubulinea is a phylogenetically stable higher-level taxon within Amoebozoa, morphologically characterized by monoaxially streaming and cylindrical pseudopods. Contemporary phylogenetic reconstructions have largely relied on SSU rDNA, and to a lesser extent, on actin genes to reveal the relationships among these organisms.

The Tubulinea are a group of strictly amoeboid amoebozoans that are capable of producing tubular pseudopodia. See also: Amoeba: much weirder than you think; Tubulinea: the paragons of amoeboids.

Other articles where Tubulinea is discussed: protozoan: Annotated classification: Tubulinea Either naked or testate amoebae. Can produce tubular subcylindrical pseudopodia. Taxa lack centrosomes and flagellated stages.

The Tubulinea are a major class of Amoebozoa, including most of the larger and more familiar amoebae like Amoeba, Arcella, and Difflugia. During locomotion most Tubulinea have a roughly cylindrical form or produce numerous cylindrical pseudopods.
