An updated view on the long‐term survival and significance of marine protist resting stages

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Resting stages of protists act as biological time capsules when buried in marine sediments, preserving viable cells that enable the study of ecological and evolutionary processes across timescales. Recent studies have extended the known viability in diatoms to several millennia and in dinoflagellates to over a century, while also identifying ...

EF-1α silencing by feeding RNAi suppresses resting cyst formation in Colpoda cucullus Nag-1 strain [PDF]

open access: yesInvertebrate Survival Journal, 2016
It is reported that the expression level of EF-1α in Colpoda cucullus Nag-1 is markedly enhanced within several hours after the onset of encystment induction. In this study, the Colpoda strain (stock EQ-1) known to promptly encyst also showed early EF-1α

Origin of Mutualism Between Termites and Flagellated Gut Protists: Transition From Horizontal to Vertical Transmission

open access: yesFrontiers in Ecology and Evolution, 2020
Lower termites, as well as their sister group, the subsocial wood-feeding cockroach Cryptocercus, rely on flagellated eukaryotic symbionts in the hindgut to cooperatively digest their wood diet. In Cryptocercus these flagellates undergo encystment cycles

Abundance, Diversity and Metabolomic Profiles of Soil Cyanobacteria‐Dominated Microbial Communities Under Long‐Term Differential Management in an Olive Orchard

open access: yesEnvironmental Microbiology, Volume 28, Issue 7, July 2026.
Sustainable management in a semi‐arid olive orchard increased abundance and diversity of nitrogen‐fixing cyanobacteria, shifting dominance towards Nodosilinea and Nostoc, while conventional soils were dominated by Leptolyngbya. Metabolomics showed stress‐related lipid and vitamin production under conventional management versus enhanced amino acids and ...

Deciphering the soybean root rot pathogen Phytophthora sojae: Signaling pathways, transcriptional regulation, and effector biology

open access: yesNew Plant Protection, Volume 3, Issue 2, June 2026.
This review highlights how Phytophthora sojae utilizes unconventional lineage‐specific signaling networks, including unique G protein‐coupled receptor fusions, expanded kinases, and rapidly evolving effectors, to infect soybeans. Understanding these divergent molecular paradigms reveals critical vulnerabilities in this destructive pathogen, offering ...

Resistance, biguanide sorption and biguanide-induced pentose leakage during encystment of Acanthamoeba castellanii

open access: yes, 2004
Aims:  This study investigates the effects of biguanides during encystment of Acanthamoeba castellanii. Methods and Results:  A non-nutrient encystment system was used to investigate the changes in the levels of sorption (uptake) of three non-cysticidal

Repositioning Imipramine for Antiparasitic Effects Against Giardia lamblia

open access: yesDrugs and Drug Candidates
Background/Objectives: Giardia lamblia is an intestinal protozoan responsible for giardiasis, a globally prevalent parasitic disease. Current therapeutic options, including nitroimidazoles and benzimidazoles, have increasing treatment failures due to ...

Heat sensitivity of first host and cercariae may restrict parasite transmission in a warming sea

open access: yesScientific Reports, 2022
To predict global warming impacts on parasitism, we should describe the thermal tolerance of all players in host–parasite systems. Complex life-cycle parasites such as trematodes are of particular interest since they can drive complex ecological changes.
