Growth Characteristics of an Estuarine Heterocystous Cyanobacterium [PDF]
Frontiers in Microbiology, 2017 A new estuarine filamentous heterocystous cyanobacterium was isolated from intertidal sediment of the Lagoa dos Patos estuary (Brazil). The isolate may represent a new genus related to Cylindrospermopsis.

Identification of Conserved and Potentially Regulatory Small RNAs in Heterocystous Cyanobacteria [PDF]
Frontiers in Microbiology, 2016 Small RNAs (sRNAs) are a growing class of non-protein-coding transcripts that participate in the regulation of virtually every aspect of bacterial physiology.

Cyanobacterial Heterocysts [PDF]
Cold Spring Harbor Perspectives in Biology, 2010 Many multicellular cyanobacteria produce specialized nitrogen-fixing heterocysts. During diazotrophic growth of the model organism Anabaena (Nostoc) sp. strain PCC 7120, a regulated developmental pattern of single heterocysts separated by about 10 to 20 photosynthetic vegetative cells is maintained along filaments.

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.
