Project description:We tested a number of rRNA removal methods (Illumina RiboZero Plus, NEBNext, NEB Core Depletion Set with custom probes, siTools Panarchaea, siTools RiboPool) on 4 model halophile species: Halobacterium salinarum, Haloferax volcanii, Haloferax meditteranei, Haloarcula hispanica). It was found that methods using custom probes (NEB Core Depletion set with HVO probes, siTools RiboPool with HVO probes) efficiently remove rRNA in species they are targeted to, and that Panarchaea efficiently removes rRNA in all 4 tested species.

Project description:By sensing changes in one or few environmental factors biological systems can anticipate future changes in multiple factors over a wide range of time scales (daily to seasonal). This anticipatory behavior is important to the fitness of diverse species, and in context of the diurnal cycle it is overall typical of eukaryotes and some photoautotrophic bacteria but is yet to be observed in archaea. Here, we report the first observation of light-dark (LD)-entrained diurnal oscillatory transcription in up to 12% of all genes of a halophilic archaeon Halobacterium salinarum NRC-1. Significantly, the diurnally entrained transcription was observed under constant darkness after removal of the LD stimulus (free-running rhythms). The memory of diurnal entrainment was also associated with the synchronization of oxic and anoxic physiologies to the LD cycle. Our results suggest that under nutrient limited conditions halophilic archaea take advantage of the causal influence of sunlight (via temperature) on O2 diffusivity in a closed hypersaline environment to streamline their physiology and operate oxically during nighttime and anoxically during daytime. This publication consists of five experiments, known as A, B, C, Control-1, and Control-2. A,B, and C are entrained as described in the publication, and Control-1 and Control-2 were not entrained.
