Average normalized expression patterns of significantly co-expressed features within the WGCNA module 23 for Richelia (103 genes, SE ± 0.21) and Rhizosolenia (105 contigs, SE ± 0.15). Key features within this module relating to potential exchange of resources are a TRAP = tripartite ATP-independent periplasmic and nitrogenase gene (nifHDKETWX) in Richelia and transporters for ammonium, amino acids, major facilitator superfamily (MFS) and efflux and EAMA-like transporters in Rhizosolenia. Gray shading highlights dark hours (7 p.m. to 6 a.m.) while light periods are white (6 a.m. to 7 p.m.)
