Putative sponge biomarkers in unicellular Rhizaria question an early rise of animals [PDF]
Nature Ecology & Evolution, 2019 The dawn of animals remains one of the most mysterious milestones in the evolution of life. The fossil lipids 24-isopropylcholestane and 26-methylstigmastane are considered diagnostic for demosponges-arguably the oldest group of living animals. The widespread occurrence and high relative abundance of these biomarkers in Ediacaran sediments from 635-541

Molecular insight into the sexual cycle of Radiolaria (Rhizaria) [PDF]
Approche moléculaire du cycle de vie des Radiolaires (Rhizaria) Le super-groupe des Rhizaria est l'un des plus diversifiés et le moins décrit parmi le monde microbien eucaryote. Bien que les rhizaires aient attiré l'attention des biologistes pendant plus d'un siècle, leur conservation fastidieuse en laboratoire a entravé une ...

Under the Cover of Darkness: A Transcriptomic Exploration of Clubroot During the Night. [PDF]
Plant DirectABSTRACT Plasmodiophora brassicae (Phytomyxea, Rhizaria) is the etiological agent of clubroot disease, one of the most important diseases of Brassicaceae crops. Alteration of metabolism and hormone homeostasis leads to the formation of tumor‐like galls in the roots of affected plants.

The Vampyrellid Amoebae (Vampyrellida, Rhizaria)
Protist, 2022 The Vampyrellida (Endomyxa, Rhizaria) is a group of free-living, predatory amoebae, which is most closely related to the Phytomyxea (plasmodiophorids and phagomyxids). It encompasses about 50 credibly described species that have a characteristic life history with the regular alternation of trophic amoebae and immobile digestive cysts.

Fog, Symbiosis, and Survival: The Ecological Architecture of the Grit Crust From the Atacama Desert Represents a Lichen Holobiome Rather Than a Soil Microbiome. [PDF]
Environ MicrobiolMulti‐marker metabarcoding (16S rRNA, 18S rRNA, ITS2) of the fog‐dependent grit crust in the Atacama Desert reveals a community structured by lichen symbioses rather than typical soil‐derived microbial assemblages. The green algal photobiont Trebouxia dominates the eukaryotic community, accompanied by lichenized Caliciales and lichen‐associated ...

Comparative Metabarcoding of ITS1, ITS2, and Full-Length ITS Reveals Marker- and Tissue-Specific Variation in Fungal Community Profiling in Potato. [PDF]
Plant Environ InteractABSTRACT Accurate profiling of plant‐associated fungal and oomycete communities depends critically on the choice of ITS marker. Using Illumina sequencing for ITS1/ITS2 and PacBio HiFi sequencing for full‐length ITS (ITSf), we compared read recovery, taxonomic assignment depth, and diversity patterns across potato leaf and root tissues.

Post-LECA Origin and Diversification of an Axonemal Outer Arm Dynein Motor. [PDF]
Cytoskeleton (Hoboken)ABSTRACT Dyneins were present in the last eukaryotic common ancestor (LECA) and play key roles in eukaryotic biology. Axonemal dyneins form the inner and outer arms that power ciliary beating, and it has long been recognized that outer arms in some organisms contain two different heavy chain motors, whereas those from other species contain a third unit
