gRodon-predicted minimal doubling times. Box and whisker plots of genomic potential for minimal doubling times predicted by gRodon for SAR11, SAR86, Bacteroidetes, and Aurantivirga MAGs, retrieved from 2018 spring phytoplankton bloom. Boxes indicate 25th and 75th percentile, and the mean is drawn as solid line. Whiskers represent 1.5× interquartile range, and outliers are not visualized. Points indicate the results of individual MAGs. Dotted line indicates threshold between oligotrophs (minimal doubling time >5 hours) and copiotrophs (minimal doubling time <5 hours), according to the authors of gRodon.
