Fig. 7From: Genomic reconstruction of fossil and living microorganisms in ancient Siberian permafrostRelative abundance of proteins identified from each MAG recovered from 3.4 m sample. These proteins were involved in carbon and energy metabolism and coping with cold, osmotic, and oxidative stresses. The relative abundance refers to the balanced spectral counts of each identified protein, whereas total number of proteins indicated all proteins identified from each MAGBack to article page
