(1) Our recent data on reticulopodial motility are discussed in an historical context, and a model for foram motility, based on motile microtubules, is presented.
Foraminifer
Definition:
(n.) One of the foraminifera.
Example Sentences:
(1) After treatment of cells of the foraminifer Allogromia laticollaris Arnold (protozoa, rhizopoda) with the volatile anesthetic halothane in concentrations of more than 1 mM no cytoplasmic microtubules are demonstrable.
(2) The motility of this cold-adapted foraminifer therefore appears fully comparable to the motility of allogromiid foraminifers from temperate waters.
(3) These two classes of macromolecules are also present in the shells of a foraminifer and in various mollusks, both of which are formed by the "organic matrix-mediated" biomineralization process.
(4) Transient shape changes of organelles translocating along microtubules are directly visualized in thinly spread cytoplasmic processes of the marine foraminifer.
(5) Electron microscopic investigations on the foraminifer Allogromia laticollaris showed that after treatment with 10(-3) M vinblastine tubulin paracrystals can be demonstrated in intermitotic nuclei.
(6) Cytoskeletal inhibitors were used as probes to test the involvement of microtubules and actin microfilaments in the development, motility, and shape maintenance of the pseudopodial networks (i e, reticulopodia) of the foraminifers Allogromia sp strain NF and Allogromia laticollaris.
(7) We summarize our recent immunocytochemical characterization of the reticulopodial cytoskeleton of two allogromiid foraminifers and our pharmacologic dissection of its motility.
