Project description:Cyanobacteria are oxygenic photoautotrophs notable for their ability to utilize atmospheric CO2 as the major source of carbon. The prospect of using cyanobacteria in converting solar energy and high concentrations of CO2 (e.g. flue gas from coal power plants) efficiently into biomass and renewable energy sources is of interest to many research fields. In order to guide further advances in this area, a better understanding about the metabolic changes that occur under conditions of high CO2 is important. The objective of this study is to utilize genome-wide microarray expression profiling in the unicellular diazotrophic cyanobacterium Cyanothece 51142 grown in 8% CO2-enriched air and to determined the impact of high CO2 on cyanobacterial cell physiology and growth. Study of metabolic and cellular adaptations to high CO2 conditions in the unicellular diazotrophic cyanobacterium Cyanothece 51142. Two-condition experiment: 0.03% CO2 vs. 8% CO2. Biological replicates: 2; technical replicates: 3; Spots/ORF: 3 per Chip. Samples were collected at 7 time points over a period of two days, namely, Day1_30minLight (30min), Day1_2hrsLight (2hr), Day1_6hrsLight (6hr), Day1_1hrsDark (13hr), Day1-6hrsDark (18hr), Day2_6hrsLight (30hr) and Day2_6hrsDark (42hr).

Project description:Transcriptional profiling of a unicelluar diazotrophic cyanobacterium Cyanothece sp. ATCC 51142 in constant light under nitrogen fixing condition. The controls comprised of equimolar pool of RNA from all time points. Cyanothece sp. ATCC 51142 was grown in BG-11 medium without nitrate. The culture was entrained under 12 h alternate light/dark cycles for 96 h and released in constant light (LL). Nine samples were for two consecutive cycles under LL, at times when the culture underwent transitions in its photosynthetic and respiratory phases, as indicated by the exit CO2 and O2 profiles. Two biological replicates, two technical replicates and a dye swap were analyzed for each sample from individual time points.

Project description:C. albicans is a dimorphic yeast which can switch from budding yeast and to hyphal forms and this property is essential for biofilm establishment and maturation. C. albicans undergoes this yeast-to-hyphal switch in response to high CO2. The purpose of this study is to use RNA-seq to investigate pathways whose genes are differentially expressed when C. albicans biofilms are grown in a physiologically relevant elevated (5%) CO2 environment compared to a low/atmospheric (0.03%) CO2 environment. We report that in C.albicans biofilms grown under 5% CO2 conditions, genes controlled by core biofilm regulatory transcription factors such as Brg1, Efg1, Ndt80, and Bcr1 are overall expressed at significantly higher levels compared to those grown in 0.03% CO2 conditions. We find that genes encoding glucose and amino acid transporters, as well as genes previously found to be involved in the response to Ketoconazole treatment, are significantly upregulated in 5% CO2 C. albicans biofilms. Overall, these data suggest a high CO2 environment enhances biofilm formation of C. albicans and may also increase antifungal tolerance of such biofilms.

Project description:We used RNA-Seq to query the Chlamydomonas reinhardtii transcriptome for regulation by CO2 concentration and by the transcription regulator CIA5(CCM1). Both CO2 concentration and CIA5 are known to play roles in induction of an essential CO2-concentrating mechanism (CCM), but the degree of interaction and the extent of global regulation beyond the CCM were not previously understood. We compared the transcriptome of a wild type strain vs. a cia5 strain under 3 CO2 supply conditions: high CO2 (H-CO2; 5%); low CO2 (L-CO2; 0.03 to 0.05%); and very-low CO2 (VL-CO2; <0.02%). Our goals were to: 1) reveal candidate genes that, through changes in their expression, distinguish multiple acclimation states induced by H-CO2, L-CO2, and VL-CO2; 2) reveal genes regulated directly or indirectly by CIA5; and 3) reveal genes responding to the interaction between CIA5 and changes in CO2 concentration. Our results revealed a small group of genes as encoding putative Ci transporters based on their expression patterns. The results also showed a massive and much broader impact on global gene regulation by CIA5/CCM1, which directly or indirectly affected 15% of the Chlamydomonas genome. The transcriptomes under L-CO2 and VL-CO2 conditions were not significantly different, suggesting that these two acclimation states must be controlled by mechanisms operating beyond transcript abundance.
