(Submitter supplied) Deletion of the global transcription factor PacR in Anabaena triggers heterocyst formation even in NO3- containing medium, likely due to impaired NO3- uptake and disrupted NH4+ assimilation in the GOGAT cycle. This phenotype may be exacerbated by reduced PSI-yield and reduced expression of ferredoxin, which may lead to less reducing equivalents for nitrogen uptake and fixation. These results highlight PacR’s role as a global regulator of carbon metabolism and photosynthesis while also establishing its involvement in regulating nitrogen metabolism.
