Project description:Cryptomonas sp. was grown under phototrophic conditions, glucose supplemented phototrophic conditions and 3 different dissolved organic carbon (DOC) concentrations: 1.5, 30 and 90 mg C l−1. The objective was to study the adaptations that make Cryptomonas sp. thrive under high DOC conditions.

Project description:Here we show that the phytochrome-less chlorophyte Chlamydomonas reinhardtii retains a functional pathway to synthesize the linear tetrapyrrole (bilin) precursor of the phytochrome chromophore. Reverse genetic, metabolic inactivation and bilin rescue experiments establish that this pathway is needed for heme iron acquisition and for the diurnal transition to phototrophic growth. RNA-Seq measurements reveal a bilin-dependent signaling network that is necessary for the heterotrophic to phototrophic transition. These results imply the presence of a novel bilin sensor pathway that may be widely distributed amongst oxygenic photosynthetic organisms.

We isolated RNA from heterotrophic suspension cultures of 4A+ WT and the hmox1 mutant grown in the presence or absence of 0.1 mM BV IXM-NM-1 before and after transfer to low light.

Project description:The principles governing acquisition and interspecies exchange of nutrients in microbial communities and how those exchanges impact community productivity are poorly understood. Here, we examine energy and macronutrient acquisition in unicyanobacterial consortia for which species-resolved genome information exists for all members, allowing us to use multi-omic approaches to predict species’ abilities to acquire resources and examine expression of resource-acquisition genes during succession. Metabolic reconstruction indicated that a majority of heterotrophic community members lacked the genes required to directly acquire the inorganic nutrients provided in culture medium, suggesting high metabolic interdependency. The sole primary producer in consortium UCC-O, cyanobacterium Phormidium sp. OSCR, displayed declining expression of energy harvest, carbon fixation, and nitrate and sulfate reduction proteins but sharply increasing phosphate transporter expression over 28 days. Most heterotrophic members likewise exhibited signs of phosphorus starvation during succession. Though similar in their responses to phosphorus limitation, heterotrophs displayed species-specific expression of nitrogen acquisition genes. These results suggest niche partitioning around nitrogen sources may structure the community when organisms directly compete for limited phosphate. Such niche complementarity around nitrogen sources may increase community diversity and productivity in phosphate-limited phototrophic communities.

Project description:Dunaliella tertiolecta is an extremophilic, green alga from the Chlorophyte lineage. It is found in coastal marine environments around the world. D. tertiolecta can tolerate extremes of heat, light, pH, and salinity. D. tertiolecta is under development for the production biofuels and other bioproducts because it can produce large quantities of neutral lipids, and it can be grown in open raceway ponds using only the inputs of seawater and sunlight. This isolate of D. tertiolecta (UTEX LB 999) was found in Oslofjord, Norway in 1938. This accession includes an RNA-Seq analysis of D. tertiolecta cultures grown in iron-replete (1.5 µM) or iron-deficient (0 µM) media.

Project description:In previous studies we identified the small RNA-binding protein CcaF1 that is involved in sRNA maturation and RNA turnover in Rhodobacter sphaeroides under microaerobic growth conditions (Grützner et al., 2021, Nucleic Acids Res. 49(6), doi: 10.1093/nar/gkab146). In this study we analysed the the small RNA-binding protein CcaF1 under phototrophic growth condtions to identify new RNA binding partners.

Project description:Alkalinity stress is considered to be one of the major stressors for fish in saline-alkali water. Thus, it is of great significance from both aquaculture and physiological viewpoint to understand the molecular genetic response of aquatic organisms to alkalinity stress. The objective of this study is to determine genome-wide gene expression profiles to better understand the physiology response of medaka (Oryzias latipes) to high carbonate alkalinity stress. In lab-based cultures, adult fish were exposed to freshwater and high carbonate alkalinity water .We designed a microarray containing 26429 oligonucleotides and describe our experimental results for measuring gene expression changes in the gill of carbonate alkalinity stress exposed fish.
