Diverse roles of the GlcP glucose permease in free-living and symbiotic cyanobacteria

Certain cyanobacteria can form symbiotic associations with plants, where the symbiont supplies the plant partner with nitrogen and in return obtains sugars. We recently showed that in the symbiotic cyanobacterium Nostoc punctiforme, a glucose specific permease, GlcP, is necessary for the symbiosis t...
