Fig. 1: Phylogenomic tree of selected unicellular α and β cyanobacteria.
From: α-cyanobacteria possessing form IA RuBisCO globally dominate aquatic habitats

New isolates used in this study are denoted by a red star. The tree is mid-point rooted. Gene presence/absence and copy number of RuBisCO, activases and chaperones, transcriptional regulators, carboxysome components, carbonic anhydrases and inorganic carbon transporters is indicated for each genome. The shade of gray signifies gene copy number, with genes in increased copy per genome given a darker shade.
