Conditional expression explains molecular evolution of social genes in a microbe
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
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 ...

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

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 ...

Social amoebae trap and kill bacteria by casting DNA nets
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 ...
