Frontiers in Microbiology, 2017 Colonies are an abundant form of bacterial multicellularity; however, relatively little is known about the initial stages of their construction. We have previously described that colony development of the soil bacterium Bacillus subtilis is a highly ...

LsrR quorum sensing "switch" is revealed by a bottom-up approach. [PDF]
PLoS Computational Biology, 2011 Quorum sensing (QS) enables bacterial multicellularity and selective advantage for communicating populations. While genetic "switching" phenomena are a common feature, their mechanistic underpinnings have remained elusive.

Adaptation of Bacillus thuringiensis to Plant Colonization Affects Differentiation and Toxicity
mSystems, 2021 The Bacillus cereus group (Bacillus cereus sensu lato) has a diverse ecology, including various species that are vertebrate or invertebrate pathogens. Few isolates from the B. cereus group have however been demonstrated to benefit plant growth. Therefore,

Maintenance of Microbial Cooperation Mediated by Public Goods in Single- and Multiple-Trait Scenarios [PDF]
, 2017 Microbes often form densely populated communities, which favor competitive and cooperative interactions. Cooperation among bacteria often occurs through the production of metabolically costly molecules produced by certain individuals that become ...

Subcellular localization of type IV pili regulates bacterial multicellular development
Nature Communications, 2022 AbstractIn mammals, subcellular protein localization of factors like planar cell polarity proteins is a key driver of the multicellular organization of tissues. Bacteria also form organized multicellular communities, but these patterns are largely thought to emerge from regulation of whole-cell processes like growth, motility, cell shape, and ...

Selective advantage for multicellular replicative strategies: A two-cell example [PDF]
, 2005 This paper develops a quasispecies model where cells can adopt a two-cell survival strategy. Within this strategy, pairs of cells join together, at which point one of the cells sacrifices its own replicative ability for the sake of the other cell.

Symbiotic Cell Differentiation and Cooperative Growth in Multicellular Aggregates
, 2016 As cells grow and divide under a given environment, they become crowded and resources are limited, as seen in bacterial biofilms and multicellular aggregates.

Frontiers in Microbiology, 2018 Filamentous cyanobacteria grow by intercalary cell division, which should involve distinct steps compared to those producing separate daughter cells. The N-terminal region of FtsZ is highly conserved in the clade of filamentous cyanobacteria capable of ...

Modulation of bacterial multicellularity via spatiotemporal polysaccharide secretion [PDF]
, 2020 AbstractThe 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 behaviours and the formation of higher-order community structures. Herein, we demonstrate that in

Spatial Heterogeneity of Autoinducer Regulation Systems
Sensors, 2012 Autoinducer signals enable coordinated behaviour of bacterial populations, a phenomenon originally described as quorum sensing. Autoinducer systems are often controlled by environmental substances as nutrients or secondary metabolites (signals) from ...
