Diversity of the Amoebozoa and Ciliophora Groups in Non-Human Primates Kept Ex Situ and in Their Handlers in Different Institutions in Brazil

Pathogens
Parasitic infections in non-human primates (NHPs) kept ex situ can be caused by zoonotic protists like Balantioides coli and Entamoeba histolytica. In Brazil, little is known about these infections in neotropical species.

Olfactory Tuft Cells Are Critical to Basal Inflammation, Innate Immune Response to Viral Infection, and Modulation of Quiescent Stem Cell Activation, Proliferation and Differentiation

Cell Proliferation, EarlyView.
Olfactory tuft cells communicate with other mucosal cells in maintaining olfactory epithelial immunity and sensory function. Disruption of tuft cell signalling pathways causes a skewed immune response, leading to heightened inflammation and increased activation of the quiescent stem cells, which are further exacerbated by viral infection.

A Hard Day's Night: Diel Shifts in Microbial Eukaryotic Activity in the North Pacific Subtropical Gyre

Frontiers in Marine Science, 2018
Molecular analysis revealed diel rhythmicity in the metabolic activity of single-celled microbial eukaryotes (protists) within an eddy in the North Pacific Subtropical Gyre (ca. 100 km NE of station ALOHA). Diel trends among different protistan taxonomic

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.

Predation and Protists

Protists are involved in many ecological roles, including primary production, herbivory and carnivory, and parasitism. Heterotrophic nanoflagellates are the most important consumers (grazers) of bacteria and small phytoplankton in aquatic environments ...

Systemic treatment of cutaneous leishmaniasis: A systematic review and meta‐analysis

Journal of the European Academy of Dermatology and Venereology, EarlyView.
This systematic review and meta‐analysis assessed systemic treatments for cutaneous leishmaniasis across 83 studies and 4603 patients. Treatment efficacies of meglumine antimoniate, miltefosine, azoles, pentamidine, and liposomal amphotericin B varied by region and species. Miltefosine showed consistent evidence across multiple settings.

Auxin response and PIN‐mediated transport in chlorophyte algae

Journal of Integrative Plant Biology, EarlyView.
Like multicellular plants, green algae respond to auxin and move it across their cells. However, their PIN‐like proteins do not act like plant auxin exporters, suggesting that basic auxin transport evolved early and specialized directional transport appeared later in plant evolution.

Volatile organic compounds orchestrating microbiome‐mediated crop resilience: Prospects and challenges for sustainable agriculture

Journal of Integrative Plant Biology, EarlyView.
Herbivory triggers the production of green leaf volatiles, and dense planting results in induces increased concentration of linalool emission in maize canopies. These volatiles activate plant‐soil feedback that enriches beneficial rhizosphere bacteria, enhancing resistance, though sometimes at a growth cost, thereby offering new avenues for sustainable

Neglected role of microelements in determining soil microbial communities and fruit micronutrients in loquat orchards

Frontiers in Microbiology
IntroductionThe relationships among microelements and soil microbial communities are essential for understanding the maintenance of soil's ecological functions and their effects on fruit quality in orchards.

Linking variation in genome size to cyst size in chrysophytes

Journal of Phycology, EarlyView.
Abstract Genome size varies tremendously across eukaryotes, which often contain far more DNA than expected from their biological complexity. To explain this paradox, selection‐based hypotheses propose that genome size evolves through selection acting on life‐history traits correlated with the phenotypic effects, independent of its genic content.
