Algae: An Introduction to Phycology
Another striking feature of the heterocyst is its thick wall, which is even thicker at
one or both ends of the cell, where it projects into the cell interior as a knob,
called the polar nodule (Fig. 2.5a, b, d). Terminal heterocysts, i.e. heterocysts
located ...

In this communication, we provide evidence that calcium, a key messenger in
eukaryotic cell signal transduction, is involved in heterocyst formation. 1. hetR
gene and its function Identification of the hetR gene was first reported by
Buikema and ...

Biology of the Prokaryotes
The innermost laminated glycolipid layer (L) is followed by an intermediary
homogenous layer and an outermost fibrous polysaccharide layer (H). The
giycolipid and the polysaccharide layers of the heterocyst envelope are barriers
for diffusion ...

A. Gloeotrichia, akinete next to a basal heterocyst; B. Anabaena
desikacharyiensis, series of akinetes next to an intercalary heterocyst. Note also
two terminal heterocysts; C. Anabaena desikacharyiensis, an akinete away from
the heterocyst.

Molecular Basis of Symbiosis
4.2 Substage 5. Heterocyst Differentiation and Behavior Physiologically,
heterocysts are microoxic, heterotrophic, Ni-fixing cells whose differentiation from
oxygenic photoautotrophic vegetative cells involves a hypothetically large, but
unknown ...

The Prokaryotes: Vol. 1: Symbiotic Associations, ...
Since the vegetative generation time under these conditions is also about 24
hours, heterocyst differentiation can be thought of as growing a new cell with a
different wall and a somewhat different set of enzymes. The RNA hybridization
data ...

Genomes and Genomics of Nitrogen-fixing Organisms
37-fold higher than that required to repress heterocyst differentiation in free-living
populations (Meeks, 2003). Nevertheless, vegetative cells continue to
differentiate into heterocysts. A N.N punctiforme mutant, which is defective in
nitrate ...

The Freshwater Algal Flora of the British Isles: An ...
The heterocyst is usually easy to distinguish (see introductory notes on
morphology). Species all possess the ability to form motile trichomes, most of
which are distinctive enough to be termed hormo- gonia, which lack heterocysts,
but these ...

It also explains the polarity of the filament of Gloetrichia in which akinete occurs
next to the terminal heterocyst with a zone of actively dividing cells next, grading
into narrow inactive hair cells. If an ammonium salt is added to the medium, ...
