The multicellularity genes of dictyostelid social amoebas

Nature Communications, 2016
Unicellular social amoebae aggregate to form a multicellular life stage, making them a model system for the evolution of multicellularity. Here, Glöckner et al.use a comparative genomic and transcriptomic approach to determine the origin of the genes ...

Regulation of sedimentation rate shapes the evolution of multicellularity in a close unicellular relative of animals

bioRxiv, 2021
Significant increases in sedimentation rate accompany the evolution of multicellularity. These increases should lead to rapid changes in ecological distribution, thereby affecting the costs and benefits of multicellularity and its likelihood to evolve ...

Molecular Mechanisms Involved in the Multicellular Growth of Ustilaginomycetes

Microorganisms, 2020
Multicellularity is defined as the developmental process by which unicellular organisms became pluricellular during the evolution of complex organisms on Earth. This process requires the convergence of genetic, ecological, and environmental factors.

A computational framework for testing hypotheses of the minimal mechanical requirements for cell aggregation using early annual killifish embryogenesis as a model

Frontiers in Cell and Developmental Biology, 2023
Introduction: Deciphering the biological and physical requirements for the outset of multicellularity is limited to few experimental models. The early embryonic development of annual killifish represents an almost unique opportunity to investigate de ...

Myosin IIA-mediated forces regulate multicellular integrity during vascular sprouting [PDF]

, 2019
Angiogenic sprouting is a critical process involved in vascular network formation within tissues. During sprouting, tip cells and ensuing stalk cells migrate collectively into the extracellular matrix while preserving cell-cell junctions, forming patent ...

The origin of multicellularity in cyanobacteria

BMC Evolutionary Biology, 2011
Background Cyanobacteria are one of the oldest and morphologically most diverse prokaryotic phyla on our planet. The early development of an oxygen-containing atmosphere approximately 2.45 - 2.22 billion years ago is attributed to the photosynthetic ...

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 ...

Considering Intra-individual Genetic Heterogeneity to Understand Biodiversity [PDF]

, 2019
In this chapter, I am concerned with the concept of Intra-individual Genetic Hetereogeneity (IGH) and its potential influence on biodiversity estimates. Definitions of biological individuality are often indirectly dependent on genetic sampling -and vice ...

Transcriptomic atlas of mushroom development reveals conserved genes behind complex multicellularity in fungi

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance Complex multicellularity is a major evolutionary innovation in the history of life. Mushroom-forming fungi (Agaricomycetes) represent one of the most diverse complex multicellular clades, yet the genetic bases and evolutionary origins of ...

Environmentally regulated clonal-aggregative multicellularity in a choanoflagellate

bioRxiv
Multicellularity evolved multiple times independently during eukaryotic diversification1–4. Two distinct mechanisms underpin multicellularity5: clonality (serial cell division without sister-cell separation) and aggregation (whereby independent cells ...
