An Atypical Aquaporin 1 Derived From Paramecium multimicronucleatum Functions as a Multifunctional Channel That Permeates Water, Glycerol, and Urea

Journal of Eukaryotic Microbiology, Volume 73, Issue 4, July/August 2026.
ABSTRACT Although it had been reported that the translation product of the functional aquaporin gene, aqp1, is localized to the contractile vacuole complex of Paramecium multimicronucleatum, the molecules that pass through this channel protein had not been identified. In the present study, we introduced and expressed this protein in Xenopus oocytes and

Novel micropatterning technique reveals dependence of cell-substrate adhesion and migration of social amoebas on parental strain, development, and fluorescent markers.

PLoS ONE, 2020
Cell-substrate adhesion of the social amoeba Dictyostelium discoideum, a model organism often used for the study of chemotaxis, is non-specific and does not involve focal adhesion complexes.

Genome‐Wide In Silico Analysis of the Type VI Secretion System (T6SS) Within the Morganella Genus

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
▪ Species‐specific T6SS patterns among Morganella genus (M. morganii and M. sibonii). ▪ Only one‐third of M. morganii isolates haboured a T6SS. ▪ All M. sibonii possess four T6SS clusters. ▪ M. sibonii exhibited a wide diversity of effectors compared to M. morganii.

A Natural LTR Retrotransposon Insertion in the Promoter of GhNAC140‐Dt Boosts Cotton Lint Yield

Plant Biotechnology Journal, Volume 24, Issue 6, Page 4240-4262, June 2026.
ABSTRACT Transposable elements (TEs) are fundamental drivers of crop evolution and domestication. Whereas the underlying mechanisms of TE‐mediated gene activation remain poorly understood. Lint percentage is an important yield component in cotton. Here, we report a retrotransposon insertion in the promoter of GhNAC140‐Dt, a secondary wall NAC encoding ...

Role of PKD2 in Rheotaxis in Dictyostelium [PDF]

PLoS ONE, 2014
The sensing of mechanical forces modulates several cellular responses as adhesion, migration and differentiation. Transient elevations of calcium concentration play a key role in the activation of cells following mechanical stress, but it is still unclear how eukaryotic cells convert a mechanical signal into an ion flux.

Cytokinin Detection during the Dictyostelium discoideum Life Cycle: Profiles Are Dynamic and Affect Cell Growth and Spore Germination

Biomolecules, 2019
Cytokinins (CKs) are a family of evolutionarily conserved growth regulating hormones. While CKs are well-characterized in plant systems, these N6-substituted adenine derivatives are found in a variety of organisms beyond plants, including bacteria, fungi,

Silanes to Silatranes: Robust Functionalization for Single‐Molecule Force Spectroscopy

ChemBioChem, Volume 27, Issue 9, 14 May 2026.
3‐(aminopropyl)silatrane (APS) has superior stability for surface functionalization in single‐molecule force spectroscopy experiments compared to conventional silane‐based methods. This paper utilizes bacterial adhesin attachment to demonstrate the advantages of APS‐based surface functionalization in single‐molecule unfolding experiments of a model ...

Affinity‐Based Interactome Mapping of Inositol Pyrophosphates Reveals 4/6‐PP‐InsP5‐Binding Proteins in Plants

Advanced Science, Volume 13, Issue 26, 8 May 2026.
ABSTRACT Inositol pyrophosphates (PP‐InsPs) are central regulators of eukaryotic signaling events. While certain PP‐InsP isomers have been conclusively linked to the regulation of phosphate homeostasis through interaction with SPX domain‐containing proteins in plants, the functions of the recently discovered isomer 4/6‐PP‐InsP5 remain largely unknown ...

Loss of Cln3 function in the social amoeba Dictyostelium discoideum causes pleiotropic effects that are rescued by human CLN3.

PLoS ONE, 2014
The neuronal ceroid lipofuscinoses (NCL) are a group of inherited, severe neurodegenerative disorders also known as Batten disease. Juvenile NCL (JNCL) is caused by recessive loss-of-function mutations in CLN3, which encodes a transmembrane protein that ...

Conserved valproic-acid-induced lipid droplet formation in Dictyostelium and human hepatocytes identifies structurally active compounds

Disease Models & Mechanisms, 2012
SUMMARY Lipid droplet formation and subsequent steatosis (the abnormal retention of lipids within a cell) has been reported to contribute to hepatotoxicity and is an adverse effect of many pharmacological agents including the antiepileptic drug valproic ...
