WebOct 15, 2024 · The unicellular green alga, Chlamydomonas reinhardtii, is a powerful model system for studying central processes in photosynthetic eukaryotes, including chloroplast biogenesis, photosynthesis, motility, light perception and cell cycle control. WebApr 11, 2024 · Goff et al. [10] reported that exposure to NAFCs resulted in increasing roundness as well as diameter for both wild type cells and cell-wall less mutants of C. reinhardtii, which was in line with our results in terms of the Chlamydomonas cell size. The increase in cell size was also a form for microalgae in response to toxic stress, which …

WebJan 1, 1999 · The haploid biflagellate unicellular photosynthetic alga Chlamydomonas shares with the yeast model systems many features which make it ideal for the isolation of cell cycle mutants. Furthermore, Chlamydomonas is a plant which divides by multiple fission. These features suggest that Chlamydomonas will provide unique insight into the … WebThe Chlamydomonas cell cycle is synchronized by light-dark cycles, so in principle, these transcriptional changes could be directly responsive to light or to metabolic cues. Alternatively, cell-cycle-periodic transcription may be directly regulated by cyclin-dependent kinases. To distinguish between these possibilities, we analyzed ...

Multiple fission is found in many species of green algae as well as other single-celled eukaryotes [ 6 ], and has some similarity to elements of non ...
WebA recent study by Lin et al. has made an interesting attempt to connect SUMOylation to cell-cycle control in Chlamydomonas. Chlamydomonas normally performs cell enlargement during a prolonged G1 phase before undergoing multiple cell fission events in a series of rapid alternating S phases and mitoses (S/M), to produce uniform daughter cells ...
