Chlamydomonas species are widely distributed worldwide in soil and fresh water, of which Chlamydomonas reinhardtii is one of the most common and widespread. [1] C. reinhardtii is an especially well studied biological model organism , partly due to its ease of culturing and the ability to manipulate its genetics.
Chlamydomonas (/ ˌ k l æ m ɪ ˈ d ɒ m ə n ə s,-d ə ˈ m oʊ-/ KLAM-ih-DOM-ə-nəs, -də-MOH-) is a genus of green algae consisting of about 150 species [2] of unicellular flagellates, found in stagnant water and on damp soil, in freshwater, seawater, and even in snow as "snow algae". [3]
The cell body is covered in a cell wall, with the protoplast entirely or partially lined up next to the wall. Cells are uninucleate (i.e. with one nucleus). There is generally a single chloroplast, which is often cup-shaped or sometimes stellate or discoid; pyrenoids may be present or absent.
The photoreceptors are found in the plasma membrane overlaying the pigmented bodies. The eyespot apparatus of Euglena comprises the paraflagellar body connecting the eyespot to the flagellum. In electron microscopy, the eyespot apparatus appears as a highly ordered lamellar structure formed by membranous rods in a helical arrangement. [3]
I-CreI is a homing endonuclease whose gene was first discovered in the chloroplast genome of Chlamydomonas reinhardtii, a species of unicellular green algae. [1] It is named for the facts that: it resides in an Intron; it was isolated from Clamydomonas reinhardtii; it was the first (I) such gene isolated from C. reinhardtii.
