Specific mutations in the permease domain of septal protein SepJ differentially affect functions related to multicellularity in the filamentous cyanobacterium Anabaena

Ramos León, Félix Arévalo, Sergio Mariscal, Vicente

Filamentous, heterocyst-forming cyanobacteria are multicellular organisms in which growth requires the activity of two interdependent cell types that exchange nutrients and regulators. Vegetative cells provide heterocysts with reduced carbon, and heterocysts provide vegetative cells with fixed nitrogen. Additionally, heterocyst differentiation...

ZipN is an essential FtsZ membrane tether and contributes to the septal localization of SepJ in the flamentous cyanobacterium Anabaena

Camargo Bernal, Sergio Picossi Goñi, Silvia María Corrales Guerrero, Laura

The organismic unit of heterocyst-forming cyanobacteria is a filament of communicating cells connected by septal junctions, proteinaceous structures bridging the cytoplasms of contiguous cells. This distinct bacterial organization is preserved during cell division. In Anabaena, deletion of the zipN gene could not be segregated. We generated...
