Chlorosis is not a dead end for cyanobacteria; actually they are able to regenerate within a few days after the addition of a nitrogen source and start to divide again. To gain deeper insight in this process, we examined the physiological and morphological changes during long-term nitrogen starvation and regeneration in Synechocystis sp.. The knowledge of the capacities of cyanobacteria to withstand adverse environmental conditions is fundamental to the understanding of the appearance of cyanobacteria in nature, where they play a dominant ecological role.
