Fig. 2. Global distribution of Roseobacter strains in biofilm-associated and free-living microbiota.
The distribution pattern was drawn by mapping reads from 339 (152 biofilm and mat metagenomes versus 187 seawater and hydrothermal vent-fluid metagenomes) to chromosomes of the 54 biofilm-derived Roseobacter strains using BBMap (minimum alignment identity = 0.80). All the metagenomes were normalized to 1,000,000 reads with a read length of 101 bp. Source data are provided as a Source data file.
