Structure and function of the Arctic and Antarctic marine microbiota as revealed by metagenomics
Abstract Background The Arctic and Antarctic are the two most geographically distant bioregions on earth. Recent sampling efforts and following metagenomics have shed light on the global ocean microbial diversity and function, yet the microbiota of polar regions has not been included in such global...
