sp. PCC7120 and their biofilm counterparts. Comparative RNA-sequencing revealed a profound global reprogramming involving 17.7% of the genome, characterized by extensive cell envelope remodelling, a pronounced downregulation of anabolic activity, and the activation of multiple stress-response pathways. Stress assays revealed that nitrogen deficiency and increased salinity markedly enhanced biofilm formation, whereas iron deficiency produced contrasting effects, underscoring how metabolic state shapes the transition to surface-associated growth. These findings establish a direct connection between stress-adaptation pathways and sessile development, providing a framework for harnessing cyanobacterial biofilms in environmental applications.
