Metaproteomics reveal that rapid perturbations in organic matter prioritize functional restructuring over taxonomy in western Arctic Ocean microbiomes

摘要

Taxonomic distributions in Bering Strait ( ) and Chukchi Sea ( ) bacterial classes under differing organic matter conditions (OM input: ; control: ) during 10 day shipboard experiments. Relative abundance contribution of major taxonomic classes (>1%) from the proteome datasets (protein) and by 16S rRNA gene sequencing (16S rRNA). The asterisk symbol denotes classes that comprise > 1% of proteome dataset but <1% of 16S rRNA dataset; The hat symbol denotes classes that comprise > 1% of 16S rRNA dataset but <1% of proteome dataset. Control samples from the Chukchi Sea incubations at day 1 were compromised and excluded from the analysis. Percent of peptides attributed to the major taxonomic classes compared with the percent of 16S rRNA genes identified per taxonomic class
