2. When exposed to environmental stress or placed in novel conditions, cyanobacteria differentiate into hormogonia.
3. Hormogonium differentiation is critical for the establishment of nitrogen-fixing plant cyanobacteria symbioses, particularly those between Nostoc cyanobacteria and their hosts.
4. Hormogonia are motile fibers. It is shaped at the hour of vegetative multiplication in filamentous cyanobacteria.
