Cyanobacterial energy capture and macronutrient acquisition during succession. Expression of Phormidium sp. OSCR proteins involved in light energy capture and carbon fixation (A), nitrogen and phosphorus acquisition (B) and sulfur acquisition (C), expressed as a percentage of total spectral counts per sample attributed to this species. The expression of the large subunit of the cyanobacterial beta’ subunit of RNA polymerase, RpoC1, is provided for reference in all panels. Data are plotted on a log₂ scale; error bars represent the 95% confidence interval of the mean. For energy and carbon capture systems (A), data represent a sum of all the subsystem-specific cyanobacterial gene products notated in Supplementary Table S2.
