Microstome–macrostome transformation in the polymorphic ciliate Tetrahymena vorax leads to mechanosensitivity associated with prey-capture behaviour

Heidi K. Grønlien, Bjarne Hagen, Olav Sand
Journal: Journal of Experimental Biology
J Exp Biol (2011) 214 (13): 2258–2266.
DOI: https://doi.org/10.1242/jeb.055897
Published: 1 July 2011
...Heidi K. Grønlien; Bjarne Hagen; Olav Sand SUMMARY Ciliates feed by phagocytosis. Some ciliate species, such as Tetrahymena vorax , are polymorphic, a strategy that provides more flexible food utilization. Cells of the microstomal morph of T. vorax feed on bacteria, organic particles and organic...

Chemo-accumulation without changes in membrane potential in the microstome form of the ciliate Tetrahymena vorax

Heidi K. Grønlien, Anna Kari Rønnevig, Bjarne Hagen, Olav Sand
Journal: Journal of Experimental Biology
J Exp Biol (2010) 213 (23): 3980–3987.
DOI: https://doi.org/10.1242/jeb.042903
Published: 1 December 2010
... Tetrahymena vorax . Effects of chemo-attractants on the membrane potential of Tetrahymena have not been previously reported. Microstome T. vorax cells aggregated close to a point source of l -cysteine and the complex meat hydrolysate proteose peptone. Chemo-accumulated cells displayed a significantly higher...

In the polymorphic ciliate Tetrahymena vorax , the non-selective phagocytosis seen in microstomes changes to a highly selective process in macrostomes

Heidi K. Grønlien, Trond Berg, Arne M. Løvlie
Journal: Journal of Experimental Biology
J Exp Biol (2002) 205 (14): 2089–2097.
DOI: https://doi.org/10.1242/jeb.205.14.2089
Published: 15 July 2002
...Heidi K. Grønlien; Trond Berg; Arne M. Løvlie SUMMARY Ciliates use phagocytosis to acquire edible particles. The polymorphic ciliate Tetrahymena vorax appears in two forms (`microstomes' and`macrostomes'). Transformation of microstomes into macrostomes takes place in the presence of the ciliate...
