ThesisCharacterization of a putative extracytoplasmic function (ECF) sigma factor, [sigma]G, and its cognate anti-sigma factor in Nostoc punctiformeCassel, NicoleAkinetes 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 . . .
ThesisCharacterization of eleven genes putatively associated with akinete development in Nostoc punctiformeTamaddoni, SassanThe cyanobacterium, Nostoc punctiforme is capable of differentiating into various cell types that allow adaptation and survival under various environmental threats. It has proven to be a unique model system for investigating genetic regulation leading . . .
