Nitrogen Fixation Mutants of the Actinobacterium Frankia Casuarinae CcI3 [PDF]
, 2017 Frankia is a representative genus of nitrogen-fixing (N2-fixing) actinobacteria; however, the molecular mechanisms underlying various phenomena such as the differentiation of a N2 fixation-specific structure (vesicle) and the regulation of N2 fixation ...

A combinatorial strategy of alternative promoter use during differentiation of a heterocystous cyanobacterium [PDF]
, 2017 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 ...

Heterocyst Differentiation in Cylindrospermum licheniforme: Studies on the Role of Transcription [PDF]
Microbiology, 1984 Heterocysts of the cyanobacterium Cylindrospermum licheniforme occur at the ends of the filaments. These cells, specialized for aerobic N2 fixation, synchronously differentiate after the fragmentation of filaments grown in a medium free of combined nitrogen.

Differential near-infrared imaging of heterocysts using single-walled carbon nanotubes
Photochemical & Photobiological Sciences, 2022 AbstractThe internalization of near-infrared (NIR) optical nanoprobes in photosynthetic microbes can be exploited for applications ranging from energy conversion to biomolecule delivery. However, the intrinsic, species-dependent properties of microbial cell walls, including their surface charge density, composition, thickness, and elasticity, can ...
