Benzimidazole Anthelmintic Compounds Albendazole and Fenbendazole Show Distinct Toxicity on the Nitrogen Fixing Bacterium Mesorhizobium loti and Its Symbiosis With Lotus japonicus

Environmental Toxicology, EarlyView.
ABSTRACT Veterinary medicines, which reach the soil mostly through the application of contaminated manures, can affect beneficial soil microorganisms, such as nitrogen‐fixing rhizobia bacteria, which engage in important symbiotic associations with plants.

Maximizing eDNA detections of rare marine organisms: A case study of a delphinid species

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental DNA (eDNA) is an emerging tool for surveying marine organisms. Advances in molecular assay designs and bioinformatic methods provide new opportunities for detecting rare species; however, overcoming methodological challenges of rare species detection remains an important obstacle for the widespread deployment of eDNA methods for ...

Sperm Head–Tail Coupling Apparatus Diversity and Common Themes Among Species

Andrology, EarlyView.
ABSTRACT Background A stable connection between the sperm head (containing the nucleus and acrosome) and tail (containing the axoneme, mitochondrial sheath, and periaxonemal structures) is critical for fertility. This connection is mediated by a series of nuclear, cytoplasmic, and centriole components that make up the head–tail coupling apparatus (HTCA)

Latitude- and depth-driven divergence in protist trophic strategies revealed by a machine learning model

Frontiers in Microbiology
Protists are ubiquitous across the ocean, holding different roles in the food web depending on their trophic capabilities. Many protists are mixotrophs, which are capable of both photosynthesizing and ingesting prey.

Acquisition, Maintenance, and Ecological Roles of Kleptoplasts in Planoglabratella opercularis (Foraminifera, Rhizaria)

Frontiers in Marine Science, 2020
Kleptoplasty or acquisition of chloroplasts from ingested photosynthetic organisms, is thought to be a key factor in determining the trophic requirements and carbon mineralization of foraminifera, consequently influencing their ecology, evolution, and ...

Two Metschnikowia nectar yeast species have similar volatile profiles but elicit differential foraging in bee pollinators

Ecological Entomology, EarlyView.
Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.

Diversity and composition of gut protist in young rural Zimbabwean children

Frontiers in Microbiomes
BackgroundThe human gut microbiome harbours diverse species of archaea, bacteria, fungi, protists and viruses. To date, most gut microbiome studies have focused on bacteria, neglecting other microbial communities.

Houses made by protists [PDF]

Current Biology, 2011
What kind of structures are we talking about? Portable protective cases, known as tests, made by single-celled organisms out of collected building materials.What are the organisms that can do this? There are two distinct types of single-celled eukaryotes with this ability.

Hsp70 diversification and repurposing across the tree of life: Lessons from the evolutionary and mechanistic trajectory of the Hsp70–Hsp110 chaperone system

The FEBS Journal, EarlyView.
Evolutionary and mechanistic divergence in the Hsp70–Hsp110 chaperone system. Prokaryotic Hsp70s probably diversified into multiple orthologues that cooperated with co‐chaperones such as JDPs and NEF, forming increasingly complex proteostasis networks.
