The Sanger sequencing method produces relatively long DNA sequences of unmatched
quality and has been considered for long time as the gold standard for sequencing DNA …

Pelagic microbes have adopted distinct strategies to inhabit the pelagial of lakes and
oceans and can be broadly categorized in two groups: free‐living, specialized oligotrophs …

Determining the phylogenetic origin of mitochondria is key to understanding the ancestral
mitochondrial symbiosis and its role in eukaryogenesis. However, the precise evolutionary …

The crossing of environmental barriers poses major adaptive challenges. Rareness of
freshwater-marine transitions separates the bacterial communities, but how these are …

Ammonia-oxidizing archaea (AOA) play a key role in the aquatic nitrogen cycle. Their
genetic diversity is viewed as the outcome of evolutionary processes that shaped ancestral …

We present a metagenomic study of Lake Baikal (East Siberia). Two samples obtained from
the water column under the ice cover (5 and 20 m deep) in March 2016 have been deep …

The dark ocean microbiota represents the unknown majority in the global ocean waters. The
SAR202 cluster belonging to the phylum Chloroflexi was the first microbial lineage …

Lake Baikal is the deepest lake in the world. Its depth provides the only bathypelagic (>
1000 m deep) freshwater habitat on Earth and its oxic, ultra‐oligotrophic features make it a …

Until recently, the data on the diversity of the entire microbial community from the Baltic Sea
were relatively rare and very scarce. However, modern molecular methods have provided …

Abstract Background The Black Sea is the largest brackish water body in the world, although
it is connected to the Mediterranean Sea and presents an upper water layer similar to some …
