Chlamydomonas cell wall
WebCells of Chlamydomonas reinhardtii Dang. wild type and the cell-wall mutants cw2 and cw15 were grown synchronously. The two mutants secreted copious amounts of cell-wall-like glycoproteins into the culture medium in contrast to the wild type which released only minor quantities. Both the secreted proteins as well as those present in the lumen of the … WebApr 14, 2009 · Fifteen mutant strains of Chlamydomonas reinhardi were isolated which showed defects in some aspect of the process of cell-wall formation. Genetic analyses indicated that most of the mutations were due to single gene changes; two were anomalous in that non-Mendelian segregations were obtained on crossing with other genotypes, and …

WebChlamydomonas is a small (<10 um) unicellular, mobile organism. It is roughly spherical in shape with two anterior flagellae that it uses to ‘swim’ in a breast-stroke-like manner. Unlike many green algae, the cell wall is not made of cellulose (as it is in land plants) but instead of a glycoprotein. WebAbstract. This chapter describes the wall of vegetative and zygotic cells of Chlamydomonas reinhardtii, Chlamydomonas eugametos, Chlamydomonas monoica, and cysts of Polytomella parvum, as viewed by electron microscopy and as analyzed using biochemistry and molecular genetics. Also described are lytic enzymes that disassemble …

WebChlamydomonas reinhardtii is a model green microalga capable of heterotrophic growth on acetic acid but not fatty acids, despite containing a full complement of genes for β-oxidation. Recent reports indicate that the alga preferentially sequesters, rather than breaks down, lipid acyl chains as a means to rebuild its membranes rapidly. Here, we assemble …
