  • MIB biosynthesis is light color-dependent in PE-containing Pseudanabaena
  • Growth of P. cinerea and TCA cycle were promoted under red light
  • MIB biosynthesis is co-upregulated with photosynthetic pigments under green light
  • <2% of carbon from precursor GPP was allocated for MIB compared to Chl a
