Fig. 4From: Analysis of nifH DNA and RNA reveals a disproportionate contribution to nitrogenase activities by rare plankton-associated diazotrophsComposition of nifH taxa based on DNA- and RNA-derived libraries. For all stations (A–I), the left bars represent the DNA-derived libraries and the right bars the RNA-derived libraries; “whole” refers to the average relative abundance of all samplesBack to article page
