Expression of nitrogenase enzyme clusters. (A) Spider chart depicting the differential regulation of enzymes involved in the nitrogenase cluster under various conditions (D+/D-/L+/L-). The indicated log(LFQ intensity) is in increasing order. (B) List of all the identified nitrogenase clusters and associated genes that play an important role in nitrogen-fixation. All the proteins (except the highlighted ones in grey) are significantly changing in at least one condition. D-: dark cycle without nitrate present; D+: dark cycle with nitrate present; L-: light cycle without nitrate present; L+: light cycle with nitrate present. The spider chart was prepared using Origin 2022 software.
