Total counts of genes associated with carbon-fixation via five cycles/pathways.

<p>Shown are genes associated with the reductive tricarboxylic-acid cycle (rTCA), including citryl co-A synthase/lyase, and pyruvate ferridoxin oxidoreductase (<i>oorABCD</i>). The Calvin cycle (CBB) is represented by the gene for ribulose-1,5-bisphosphate carboxylase, and the reductive acetyl Co-A pathway (rACP) is estimated by CO dehydrogenase. Malonate semialdehyde reductase and 4-hydroxybutyryl-CoA dehydratase are used as proxies for the 3-hydroxypropionate cycle (3-HP), and the 3-hydroxypropionate/4-hydroxybutyrate cycle (3-4HP), respectively. All columns are normalized to the smallest total dataset.
