Cell Cycle by Light Intensity in Chlamydomonas reinhardtii

Project description:Photosynthetic organisms coordinate their metabolism and growth with diurnal light, which can range in intensity from limiting to inhibitory. To gain a comprehensive understanding of how diurnal regulatory circuits interface with sensing and response to various light intensities, we performed a systems analysis of synchronized Chlamydomonas reinhardtii populations acclimated to low, moderate, and high diurnal light. Transcriptomic and proteomic data revealed that Chlamydomonas’ rhythmic gene expression program is resilient to limiting and excess light. Although gene expression is dynamic over the diurnal cycle, Chlamydomonas populations acclimated to low and high diurnal light exhibit constitutive phenotypes with respect to photosystem abundance, thylakoid architecture, and non-photochemical quenching that persist through the night. This suggests that cells harbor a “memory” or anticipation of the daylight environment. The integrated data constitute an excellent resource for understanding gene regulatory mechanisms and photoprotection in eukaryotes under environmentally relevant conditions.

Transcriptomics analysis of the Chlamydomonas reinhardtii diurnal cycle.

Project description:Here, we report a transcriptomics analysis on a day in the life of Chlamydomonas reinhardtii. Cultures of this unicellular alga were grown in photobioreactors on a 12 h light / 12 h dark cycle. Samples were collected at regular intervals and subjected to a transcriptomics analysis by RNA-Seq.

Transcriptome analysis of Chlamydomonas reinhardtii chloroplast and mitochondria

Project description:Here, we report on the transcriptome of the organelles of the micro-alga, Chlamydomonas reinhardtii, sampled under a number of different conditions. The preparation of the RNA-Seq libraries and their analysis were performed using protocols optimized for organellar transcripts. Samples include growth in media +/– Fe, growth in media +/– Cu, diurnal growth samples collected in dark and light, and the sexual cycle.

Systems analysis of the response of photosynthesis, metabolism and growth to an increase in irradiance in the photosynthesis model organism Chlamydomonas reinhardtii

Project description:Systems analysis reveals that Chlamydomonas reinhardtii responds rapidly and flexibly to an increase in light intensity. Rising metabolite levels and post-translation regulation facilitate a rapid increase in the rate of carbon fixation and a slightly delayed increase in the rate of growth, and slower changes in protein abundance adjust allocation and minimize bottlenecks in the new conditions. Gene expression was measured from samples of Chlamydomonas reinhardtii cell cultures at four time points (two under low, four under high light) under either low (41 Âµmol) or high (145 Âµmol) light conditions in two separate bioreactors. Three biological replicate time series were sampled.

Small RNAs in Chlamydomonas reinhardtii

Project description:RNA populations in Chlamydomonas reinhardtii Keywords: Highly parallel pyrosequencing Small RNAs were prepared from Chlamydomonas reinhardtii total extracts,ligated to a 3' adaptor and a 5' acceptor sequentially, and then RT-PCR amplified. PCR products were reamplified using a pair of 454 cloning primers and provided to 454 Life Sciences (Branford, CT) for sequencing.
