Construction of Metatranscriptomic Libraries for 5′ End Sequencing of rRNAs for Microbiome Research
2021
Metatranscriptomic sequencing enables studying community-wide gene expression profiles of microbial samples and getting functional insight on their up- or downregulated pathways. However, shotgun sequencing is not the most efficient way to study expression of ribosomal RNA genes or to compare lot of samples in experimental setups. Here we describe an efficient primer-independent method for processing and barcoding libraries for directional sequencing of the 5' end region of the RNA. When applying size selection of the original RNA, the method forms an optimal solution for the simultaneous analysis of bacterial, archaeal, and eukaryotic rRNA diversity.
Effects of hydrostatic pressure on yeasts isolated from deep-sea hydrothermal vents
2015
International audience; Hydrostatic pressure plays a significant role in the distribution of life in the biosphere. Knowledge of deep-sea piezotolerant and (hyper)piezophilic bacteria and archaea diversity has been well documented, along with their specific adaptations to cope with high hydrostatic pressure (HHP). Recent investigations of deep-sea microbial community compositions have shown unexpected micro-eukaryotic communities, mainly dominated by fungi. Molecular methods such as next-generation sequencing have been used for SSU rRNA gene sequencing to reveal fungal taxa. Currently, a difficult but fascinating challenge for marine mycologists is to create deep-sea marine fungus culture c…
