Heterocyst differentiation that occurs in some filamentous cyanobacteria, such as Anabaena
sp. PCC 7120, provides a unique model for prokaryotic developmental biology. Heterocyst …

Many multicellular cyanobacteria produce specialized nitrogen-fixing heterocysts. During
diazotrophic growth of the model organism Anabaena (Nostoc) sp. strain PCC 7120, a …

Nitrogen is generally considered one of the major limiting nutrients in plant growth. The
biological process responsible for reduction of molecular nitrogen into ammonia is referred …

Within the wide biodiversity that is found in the bacterial world, Cyanobacteria represents a
unique phylogenetic group that is responsible for a key metabolic process in the biosphere …

The pigment patterns on tropical shells are of great beauty and diversity. Their mixture of
regularity and irregularity is fascinating. A particular pattern seems to follow particular rules …

The fixation of atmospheric N2 by cyanobacteria is a major source of nitrogen in the
biosphere. In Nostocales, such as Anabaena, this process is spatially separated from …

Heterocyst differentiation in filamentous cyanobacteria provides an excellent prokaryotic
model for studying multicellular behaviour and pattern formation. In Anabaena sp. strain …

An inroad into an understanding of the complex molecular interactions on which
development is based can be achieved by uncovering the minimum requirements that …

Heterocyst‐forming cyanobacteria are filamentous organisms that perform oxygenic
photosynthesis and CO2 fixation in vegetative cells and nitrogen fixation in heterocysts …

The mechanism by which animal markings are formed is an intriguing problem that has
remained unsolved for a long time. One of the most important questions is whether the …
