Calcium-induced contraction of the rhizoplast of a quadriflagellate green alga.
The rhizoplast of Platymonas subcordiformis is a contractile organelle. Cyclic contraction and extension are induced by incubating the organism in solutions containing calcium and adenosine triphosphate. Rhizoplast contraction is functionally linked to flagellar activity.
