Modulation of bacterial multicellularity via spatio-specific polysaccharide secretion. [PDF]
The development of multicellularity is a key evolutionary transition allowing for differentiation of physiological functions across a cell population that confers survival benefits; among unicellular bacteria, this can lead to complex developmental ...

A delivered DNase toxin creates population heterogeneity through transient intoxication of siblings [PDF]
Population heterogeneity is important for multicellular behavior, as well as bet-hedging strategies. Recent findings suggest a role for bacterial toxin delivery in generating population heterogeneity, but the molecular mechanisms by which this occurs are

Bacterial Ventures into Multicellularity: Collectivism through Individuality. [PDF]
Multicellular eukaryotes can perform functions that exceed the possibilities of an individual cell. These functions emerge through interactions between differentiated cells that are precisely arranged in space.

Detection of horizontal gene transfer in the genome of the choanoflagellate Salpingoeca rosetta
Horizontal gene transfer (HGT), the movement of heritable materials between distantly related organisms, is crucial in eukaryotic evolution. However, the scale of HGT in choanoflagellates, the closest unicellular relatives of metazoans, and its possible ...

Anabaena sp. PCC 7120 grows by forming filaments of communicating cells and is considered a paradigm of bacterial multicellularity. Molecular exchanges between contiguous cells in the filament take place through multiprotein channels that traverse the ...

Interactions of PatA with the Divisome during Heterocyst Differentiation in
The Anabaena organismic unit is a filament of communicating cells. Under conditions of nitrogen scarcity, some cells along the filament differentiate into heterocysts, which are specialized in the fixation of atmospheric N2 and provide the vegetative ...

Swarming bacteria undergo localized dynamic phase transition to form stress-induced biofilms
Self-organized multicellular behaviors enable cells to adapt and tolerate stressors to a greater degree than isolated cells. However, whether and how cellular communities alter their collective behaviors adaptively upon exposure to stress is largely ...

Understanding Multicellularity: The Functional Organization of the Intercellular Space [PDF]
The aim of this paper is to provide a theoretical framework to understand how multicellular systems realize functionally integrated physiological entities by organizing their intercellular space. From a perspective centered on physiology and integration,

Cyanobacteria and the Great Oxidation Event:Evidence from genes and fossils [PDF]
Cyanobacteria are among the most ancient of evolutionary lineages, oxygenic photosynthesizers that may have originated before 3.0 Ga, as evidenced by free oxygen levels.
