||P.398 right column bottom paragraph: "In comparison, β-cyanobacteria occupy a much more diverse range of habitats, including freshwater, estuarine, and hot springs and never reach the same levels of global abundance (Badger et al., 2006). They are characterized by larger cells, larger genomes (2.2–3.6 Mb), and an array of carbon uptake transporters, including those transporters induced under low Ci (inorganic carbon, primary sources). In addition to these broadly defined α-groups and β-groups, there are small numbers of α-cyanobacteria that have been termed transitional strains (Price, 2011, primary source Rae et al., 2011)."
