Transcriptional and cellular reprogramming in Anabaena sp. PCC7120 biofilms: implications for stress response.
Highlights • The transition from a planktonic to a sessile lifestyle in Anabaena sp. PCC 7120 is driven by a massive transcriptomic reprogramming involving 17.7% of the genome. • Sessile growth involves cell envelope remodeling and lower anabolic activity. • While nitrogen deficiency and salinity promote biofilm formation, iron deficiency exerts contrasting effects on sessile development. • Stress-adaptation pathways are directly linked to biofilm development.
