Conditional expression explains molecular evolution of social genes in a microbe

open access: yesNature Communications, 2019
Genetic diversity in social genes is expected to be shaped by conflict. Here, the authors show that in Dictyostelium discoideum, social genes in fact exhibit diversification patterns consistent with relaxed purifying selection, likely due to their ...

Legionella pneumophila modulates the host cytoskeleton by an effector of transglutaminase activity

open access: yesmLife, Volume 4, Issue 3, Page 232-248, June 2025.
Abstract The bacterial pathogen Legionella pneumophila delivers more than 330 effector proteins into host cells through its Dot/Icm type IV secretion system (T4SS) to facilitate its intracellular replication. A number of these effectors modulate organelle trafficking pathways to create a membrane‐bound niche called the Legionella‐containing vacuole ...

Whole Genome Sequencing of Mutation Accumulation Lines Reveals a Low Mutation Rate in the Social Amoeba Dictyostelium discoideum

open access: yesPLoS ONE, 2012
Spontaneous mutations play a central role in evolution. Despite their importance, mutation rates are some of the most elusive parameters to measure in evolutionary biology.

Light Affects Host‐Symbiont Dynamics in the Non‐Photosynthetic Social Amoeba Symbiosis

open access: yesEcology and Evolution, Volume 15, Issue 4, April 2025.
This study highlights light‐regulated symbiosis between amoebae and two distinct Paraburkholderia species, indicating that light may be crucial for regulating amoebae‐symbiont dynamics. ABSTRACT Light significantly influences phototactic behaviors and host‐bacterial interactions of photosynthetic microorganisms such as algae.

Functional Characterization of a Novel Aquaporin from Dictyostelium discoideum Amoebae Implies a Unique Gating Mechanism*

open access: yesJournal of Biological Chemistry, 2012
Background: Aquaporins are involved in osmoregulation and cell motility. Functional D. discoideum aquaporins are missing. Results: We characterized a putatively gated aquaporin from amoebae that localizes to vacuolar structures, the plasma membrane, and ...

Functional Characterization of the Plasmodium falciparum Chloroquine-Resistance Transporter (PfCRT) in Transformed Dictyostelium discoideum Vesicles

open access: yesPLoS ONE, 2012
Background Chloroquine (CQ)-resistant Plasmodium falciparum malaria has been a global health catastrophe, yet much about the CQ resistance (CQR) mechanism remains unclear.

Social amoebae trap and kill bacteria by casting DNA nets

open access: yesNature Communications, 2016
Neutrophils secrete net-like structures made of DNA and anti-microbial peptides, which can trap and kill extracellular pathogens. Here, the authors show that such nets are also produced by so-called Sentinel cells in the multicellular slug stage of the ...
