Do the regular annual extreme water level changes affect the seasonal appearance of Anabaena in Poyang Lake? [PDF]
PeerJ, 2019 Background Poyang Lake is an ecosystem experiencing annual variations in water level of up to 14 m. Water level changes were 8.03 and 11.22 m, respectively, in the years 2013 and 2014.

Design and characterization of a synthetic minimal promoter for heterocyst-specific expression in filamentous cyanobacteria. [PDF]
PLoS ONE, 2018 Short and well defined promoters are essential for advancing cyanobacterial biotechnology. The heterocyst of Nostoc sp. is suggested as a microbial cell factory for oxygen sensitive catalysts, such as hydrogenases for hydrogen production, due to its ...

The Heterocyst-Specific Small RNA NsiR1 Regulates the Commitment to Differentiation in Nostoc
Microbiology Spectrum, 2022 Heterocysts are specialized cells that filamentous cyanobacteria differentiate for the fixation of atmospheric nitrogen when other nitrogen sources are not available.

Relationships between the ABC-exporter HetC and peptides that regulate the spatiotemporal pattern of heterocyst distribution in Anabaena. [PDF]
PLoS ONE, 2014 In the model cyanobacterium Anabaena sp. PCC 7120, cells called heterocysts that are specialized in the fixation of atmospheric nitrogen differentiate from vegetative cells of the filament in the absence of combined nitrogen.
