Covering: up to 2013 Although holo-acyl carrier protein synthase, AcpS, a
phosphopantetheinyl transferase (PPTase), was characterized in the 1960s, it was not until …

Many multicellular cyanobacteria produce specialized nitrogen-fixing heterocysts. During
diazotrophic growth of the model organism Anabaena (Nostoc) sp. strain PCC 7120, a …

Nitrogen is generally considered one of the major limiting nutrients in plant growth. The
biological process responsible for reduction of molecular nitrogen into ammonia is referred …

The new genus name Dolichospermum, for most of the planktonic former members of the
genus Anabaena, is one of the most ubiquitous bloom-forming cyanobacterial genera. Its …

Sulphate assimilation is an essential pathway being a source of reduced sulphur for various
cellular processes and for the synthesis of glutathione, a major factor in plant stress defence …

Flavodiiron proteins (FDPs, also called flavoproteins, Flvs) are modular enzymes widely
present in Bacteria and Archaea. The evolution of cyanobacteria and oxygenic …

Many filamentous nitrogen-fixing cyanobacteria protect nitrogenase from oxygen in
differentiated cells called heterocysts. Heterocyst development is controlled by the …

Cyanobacterial morphology is diverse, ranging from unicellular spheres or rods to
multicellular structures such as colonies and filaments. Multicellular species represent an …

Root ion transport systems are regulated by light and/or sugars, but the signaling
mechanisms are unknown. We showed previously that induction of the NRT2. 1 NO3 …

Background Cyanobacteria are potential sources of renewable chemicals and biofuels and
serve as model organisms for bacterial photosynthesis, nitrogen fixation, and responses to …
