The origins of parasitism in the protists
International Journal for Parasitology, 1994The origins of parasitism among the protists are, like the group itself, polyphyletic. Probably the majority of present-day parasitic forms evolved from free-living ancestors which were ingested as part of the food of their hosts, though origins from ectoparasitic forms and via a phase of facultative parasitism are possibilities, particularly among the

Graviorientation in Protists and Plants
Journal of Plant Physiology, 1999Gravitaxis, gravikinesis, and gravitropism are different graviresponses found in protists and plants. The phenomena have been intensively studied under variable stimulations ranging from microgravity to hypergravity. A huge amount of information is now available, e.g.

Protists in science communication
European Journal of ProtistologyDespite their high abundance and wide distribution in ecosystems, most protists remain unknown to the public. Although science communication approaches were developed in historical times to raise public awareness of these 'enigmatic' taxa, many aspects have not been considered in the spotlight of modern techniques.

The protist cultural renaissance
Trends in MicrobiologyProtists are key players in the biosphere. Here, we provide a perspective on integrating protist culturing with omics approaches, imaging, and high-throughput single-cell manipulation strategies, concluding with actions required for a successful return of the golden age of protist culturing.

The enigmatic protist Nephromyces
Biosystems, 1981This paper review current knowledge concerning the identity of Nephromyces, a collection of fungus-like cells found in the renal sac of all molgulid tunicates thus far examined. The following has been demonstrated: (1) The cells called Nephromyces do exist, and are not produced by their tunicate hosts, but are something foreign to these animals.

Extrusive Organelles in Protists
1978Publisher Summary This chapter discusses the extrusive organelles in protists. Extrusive organelles are membrane-bounded structures of protists, usually located in the cortical cytoplasm of these cells. Although they have different type-specific structures and functions, they all exhibit one general characteristic: they are readily discharged when ...

Biophysics of protist behaviour
Current BiologyProtists, an umbrella term first coined by Ernst Haeckel in 1866, are a vast collection of (primarily unicellular) eukaryotes that are "neither animals nor plants". This basic definition by exclusion has been exercised for centuries, even though recent advances have led to more rigorous taxonomic assignment of various protist groups.
