Genetic characterization of the hmp locus, a chemotaxis‐like gene cluster that regulates hormogonium development and motility in Nostoc punctiforme

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
