Characterization of a putative extracytoplasmic function (ECF) sigma factor, [sigma]G, and its cognate anti-sigma factor in Nostoc punctiforme

Cassel, Nicole

Akinetes are spore-like cells resistant to desiccation and cold that differentiate from vegetative cells of the filamentous cyanobacterium N. punctiforme in response to phosphate or potassium limitation and low light. Previous microarray data has iden . . .

Synergistic Effect of Deoxyanthocyanins from Symbiotic Fern Azolla spp. on hrmA Gene Induction in the Cyanobacterium Nostoc Punctiforme

Sakihama, Yasuko

The hrmA gene of the N2-fixing cyanobacterium Nostoc punctiforme functions in repressing the formation of transitory motile filaments, termed hormogonia, by plant-associated vegetative filaments. Here, we report that anthocyanins can contribute to ind . . .
