a, The root-associated N2 fixation rates of individual plants. Each symbol represents an individually measured root piece. b, The relative abundance of Ca. C. neptuna 16S rRNA gene sequence reads (magenta) in roots of individually analysed plants. One column represents one plant and each column corresponds to the measured N2 fixation rates in a. c, Phylogeny of Ca. C. neptuna (bold, magenta) within the Celerinatantimonadaceae based on 16S rRNA gene sequences (consensus tree; the scale bar is substitutions per site; the black dots indicate strong bootstrap support). Macrophytes and metazoa from which sequences were recovered are indicated on the right. Blue and magenta circles indicate the acquisition of abilities to fix N2 and to degrade pectin (Pec), respectively. C. yamalensis, Celerinatantimonas yamalensis; T. hemprichii, Thalassia hemprichii. Accession numbers and references are provided in Supplementary Data 1 and 2.
