The Nostoc–Gunnera symbiosis [PDF]
summary Gunnera L. develops a complex and intimate symbiosis with N2‐fixing cyanobacteria of the genus Nostoc, which renders the plant independent of combined nitrogen. The Nostoc‐Gunnera symbiosis exhibits unique features compared to other cyanobacterial‐plant symbioses: it is for example the only one that involves a flowering plant (angiosperm), the ...

A combinatorial strategy of alternative promoter use during differentiation of a heterocystous cyanobacterium [PDF]
Heterocystous cyanobacteria such as Nostoc sp. are filamentous photosynthetic organisms that, in response to nitrogen deficiency, undergo a differentiation process transforming certain, semi-regularly spaced cells into heterocysts, devoted to nitrogen ...

Further characterization of glycine-containing microcystins from the McMurdo Dry Valleys of Antarctica [PDF]
Microcystins are hepatotoxic cyclic peptides produced by several cyanobacterial genera worldwide. In 2008, our research group identified eight new glycine-containing microcystin congeners in two hydro-terrestrial mat samples from the McMurdo Dry Valleys ...
