Evolution of size and pattern in the social amoebas [PDF]

open access: yes, 2007
A fundamental goal of biology is to understand how novel phenotypes evolved through changes in existing genes. The Dictyostelia or social amoebas represent a simple form of multicellularity, where starving cells aggregate to build fruiting structures ...

Production of antibacterial compounds by a Steely hybrid polyketide synthase in Dictyostelium

open access: yesFEBS Open Bio, EarlyView.
By selecting appropriate production species under optimised culture conditions, new chlorinated dibenzofuran compounds, which previously could not be analysed in sufficient quantities, were identified from cellular slime mould fruiting bodies. The strong antibacterial activity exhibited by these compounds suggests a link to the ecological function of ...

Resistance of Dictyostelium discoideum membranes to saponin permeabilization

open access: yesBMC Research Notes, 2010
Background Saponin is a mild detergent commonly used to permeabilize cells prior to immunofluorescence labeling of intracellular proteins. It has previously been used to that effect in Dictyostelium discoideum amoebae.

Development of a Positive Selection High Throughput Genetic Screen in Dictyostelium discoideum

open access: yesFrontiers in Cell and Developmental Biology, 2021
The cellular slime mold Dictyostelium discoideum is a powerful model organism that can be utilized to investigate human health and disease. One particular strength of Dictyostelium is that it can be utilized for high throughput genetic screens.

The role of the cortical cytoskeleton [PDF]

open access: yes, 1996
We generated Dictyostelium double mutants lacking the two F-actin crosslinking proteins alpha-actinin and gelation factor by inactivating the corresponding genes via homologous recombination.

Interactions Between Active Matters and Endogenous Fields

open access: yesAdvanced Materials, EarlyView.
This review synthesizes endogenous field information and computational methods in contexts such as cancer, wounds, and biofilms. It organizes NAMs and AAMs by sensing, transmitting, and executing functions, compares their limitations, and from these contrasts proposes design strategies for next‐generation AAMs, offering perspectives to foster ...

Cooperative predation in the social amoebae Dictyostelium discoideum.

open access: yesPLoS ONE, 2019
The eukaryotic amoeba Dictyostelium discoideum is commonly used to study sociality. The amoebae cooperate during development, exhibiting altruism, cheating, and kin-discrimination, but growth while preying on bacteria has been considered asocial. Here we

Identification and phylogenetic analysis of Dictyostelium discoideum kinesin proteins

open access: yesBMC Genomics, 2003
Background Kinesins constitute a large superfamily of motor proteins in eukaryotic cells. They perform diverse tasks such as vesicle and organelle transport and chromosomal segregation in a microtubule- and ATP-dependent manner.

cAMP activates adenylate and guanylate cyclase of Dictyostelium discoideum cells by binding to different classes of cell-surface receptors. A study with extracellular Ca2+ [PDF]

open access: yes, 1985
cAMP induces a transient increase of cAMP and cGMP levels in Dictyostelium discoideum cells. Fast binding experiments reveal three types of cAMP-binding site (S, H and L), which have different off-rates (t0.5, 0.7-15 s) and different affinities (Kd, 15 ...

Information Transmission Strategies for Self‐Organized Robotic Aggregation

open access: yesAdvanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.
