    • Filamentous cyanobacteria are capable of gliding motility, but the mechanism of motility is not well defined. Here we present a detailed characterization of the hmp locus from Nostoc punctiforme, which encodes chemotaxis‐like proteins. Deletions of hmpB, C, D and E abolished differentiation of hormogonia under standard growth conditions, but, upon addition of a symbiotic partner exudate, the mutant strains differentiated hormogonium‐like filaments that lacked motility and failed to secrete… CONTINUE READING
