Model Organism
Chlamydomonas is used as a model organism for research on fundamental questions in cell and molecular biology such as:
- How do cells move?
- How do cells respond to light?
- How do cells recognize one another?
- How do cells generate regular, repeatable flagellar waveforms?
- How do cells regulate their proteome to control flagellar length?
- How do cells respond to changes in mineral nutrition? (nitrogen, sulfur etc.)
There are many known mutants of C. reinhardtii. These mutants are useful tools for studying a variety of biological processes, including flagellar motility, photosynthesis or protein synthesis. Since Chlamydomonas species are normally haploid, the effects of mutations are seen immediately without further crosses.
In 2007, the complete nuclear genome sequence of C. reinhardtii was published.
Channelrhodopsin-1 and Channelrhodopsin-2, proteins that function as light-gated cation channels, were originally isolated from C. reinhardtii. These proteins and others like them are increasingly widely used in the field of optogenetics.

Famous quotes containing the words model and/or organism:
“The best way to teach a child restraint and generosity is to be a model of those qualities yourself. If your child sees that you want a particular item but refrain from buying it, either because it isn’t practical or because you can’t afford it, he will begin to understand restraint. Likewise, if you donate books or clothing to charity, take him with you to distribute the items to teach him about generosity.”
—Lawrence Balter (20th century)
“The problems of the world, AIDS, cancer, nuclear war, pollution, are, finally, no more solvable than the problem of a tree which has borne fruit: the apples are overripe and they are falling—what can be done?... Nothing can be done, and nothing needs to be done. Something is being done—the organism is preparing to rest.”
—David Mamet (b. 1947)
