c-di-GMP Homeostasis Is Critical for Heterocyst Development in Anabaena sp. PCC 7120
c-di-GMP is a ubiquitous bacterial signal regulating various physiological process. Anabaena PCC 7120 (Anabaena) is a filamentous cyanobacterium able to form regularly-spaced heterocysts for nitrogen fixation, in response to combined-nitrogen deprivation

Do the regular annual extreme water level changes affect the seasonal appearance of Anabaena in Poyang Lake? [PDF]
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.

Characterization of Soil-Indigenous Cyanobacterial Strains and Bioactivity Assessment [PDF]
Some cyanobacteria isolates were collected from soil samples at various locations from governorates of Kafr El-Sheikh and El-Dakahlia. By using morphological characterizations to identify these isolates. Heterocyst-forming cyanobacteria were Anabaena sp.,

Immunocytochemical Localization of Thioredoxins in the Cyanobacteria Anabaena cylindrica and Anabaena variabilis [PDF]
Summary: Colloidal gold conjugated goat anti-rabbit IgG and specific antisera raised against purified thioredoxins from Anabaena cylindrica and Anabaena variabilis have been used to determine the localization of thioredoxin in whole filaments of A. cylindrica and A. variabilis. Vegetative cells of A.

Ubiquitin in the Prokaryote Anabaena variabilis [PDF]
The ubiquitin-dependent pathway for protein degradation has been found to play a major role in controlling protein turnover in the cell. Ubiquitin is one of the most conserved proteins yet identified, and up until now it has been thought to be present only in eukaryotes and archaebacteria.
