Physiologia Plantarum, Volume 177, Issue 3, May/June 2025.Abstract In the filamentous cyanobacterium Anabaena sp. PCC 7120, heterocyst formation is triggered by changes in the C/N‐ratio and relies on transcriptional reprogramming. The transcription factor PacR is considered a global regulator of carbon assimilation under photoautotrophic conditions, influencing the carbon concentrating mechanism and ...

Molecular Microbiology, Volume 123, Issue 1, Page 31-47, January 2025.Anabaena performs oxygenic photosynthesis in vegetative cells and N2 fixation in heterocysts. The protein ThyD is localized in thylakoid membranes: at the cell periphery in vegetative cells (v) and the cell poles in heterocyst (h). ThyD influences cell division and is required for acclimation to conditions of high light intensity.
