On the evolution of bacterial multicellularity. [PDF]

Curr Opin Microbiol, 2015
Multicellularity is one of the most prevalent evolutionary innovations and nowhere is this more apparent than in the bacterial world, which contains many examples of multicellular organisms in a surprising array of forms. Due to their experimental accessibility and the large and diverse genomic data available, bacteria enable us to probe fundamental ...

Bacterial glycocalyx integrity drives multicellular swarm biofilm dynamism [PDF]

Molecular Microbiology, 2021
Abstract Exopolysaccharide (EPS) layers on the bacterial cell surface are key determinants of biofilm establishment and maintenance, leading to the formation of higher‐order 3D structures that confer numerous survival benefits to a cell community.

Symplasmata are a clonal, conditional, and reversible type of bacterial multicellularity. [PDF]

Sci Rep, 2016
AbstractMicroorganisms are capable of remarkable social behaviours, such as forming transient multicellular assemblages with properties and adaptive abilities exceeding those of individual cells. Here, we report on the formation and structure of genets known as symplasmata produced by Pantoea eucalypti bacteria.

Resolving spatiotemporal dynamics in bacterial multicellular populations: approaches and challenges. [PDF]

Microbiol Mol Biol Rev
SUMMARY The development of multicellularity represents a key evolutionary transition that is crucial for the emergence of complex life forms. Although multicellularity has traditionally been studied in eukaryotes, it originates in prokaryotes.

Bacterial solutions to multicellularity: a tale of biofilms, filaments and fruiting bodies [PDF]

Nature Reviews Microbiology, 2014
Although bacteria frequently live as unicellular organisms, many spend at least part of their lives in complex communities, and some have adopted truly multicellular lifestyles and have abandoned unicellular growth. These transitions to multicellularity have occurred independently several times for various ecological reasons, resulting in a broad range

Exopolysaccharide microchannels direct bacterial motility and organize multicellular behavior [PDF]

The ISME Journal, 2016
Abstract The myxobacteria are a family of soil bacteria that form biofilms of complex architecture, aligned multilayered swarms or fruiting body structures that are simple or branched aggregates containing myxospores. Here, we examined the structural role of matrix exopolysaccharide (EPS) in the organization of these surface-dwelling ...

Bacterial growth in multicellular aggregates leads to the emergence of complex lifecycles [PDF]

Current Biology, 2021
ABSTRACTIn response to environmental stresses such as starvation, many bacteria facultatively aggregate into multicellular structures that can attain new metabolic functions and behaviors. Despite the ubiquity and relevance of this form of collective behavior, we lack an understanding of how the spatiotemporal dynamics of aggregate development emerge ...

Metabolic Heterogeneity and Cross-Feeding in Bacterial Multicellular Systems

Trends in Microbiology, 2020
Cells in assemblages differentiate and perform distinct roles. Though many pathways of differentiation are understood at the molecular level in multicellular eukaryotes, the elucidation of similar processes in bacterial assemblages is recent and ongoing.

Cyanobacterial Septal Junctions: Properties and Regulation

Life, 2018
Heterocyst-forming cyanobacteria are multicellular organisms that grow as chains of cells (filaments or trichomes) in which the cells exchange regulators and nutrients.

The Rosetteless gene controls development in the choanoflagellate S. rosetta. [PDF]

, 2014
The origin of animal multicellularity may be reconstructed by comparing animals with one of their closest living relatives, the choanoflagellate Salpingoeca rosetta.
