Fig. 2: 13C and 15N uptake by two different unicellular diazotrophs.

From: Heterogeneous nitrogen fixation rates confer energetic advantage and expanded ecological niche of unicellular diazotroph populations

Fig. 2

Nitrogen and carbon incorporation by a Crocosphaera and b Cyanothece shown by scatter plot of 15N:14N and 13C:12C in individual cells. Black dot-lines show threshold of 15N and 13C enrichment. c Schematic view of scatter plot. Blue, data obtained during 0D6D; Green, data obtained during 7D-12D; Orange; data obtained 1L-6L; Pink, data obtained 7L-12L. Higher 13C uptake in Crocospharea compared to Cyanothece is likely to reflect higher initial 13C enrichment in the culture for Crocosphaera: 9.7 atm% for Crocosphaera and 1.7 atm% for Cyanothece (see Methods).
