The colourless dictyochophyte Ciliophrys sp. Baltic secondarily lacks a plastid but hosts a bacterial endosymbiont

This study describes a non-photosynthetic protist, Ciliophrys sp. Baltic, which lacks a plastid but hosts a bacterial endosymbiont, providing insights into plastid loss and endosymbiont acquisition.

Comparing Symbiodiniaceae diversity across unicellular hosts, multicellular hosts, and environmental reservoirs

The paper compares Symbiodiniaceae diversity across different hosts and environments, finding distinct community structures and shared variants.

Parallel Evolution of Bacteroidota as Long-Term Endosymbionts of Insects

This study examines the parallel evolution of Bacteroidota as insect endosymbionts, showing genomic and cellular changes across multiple scale insect lineages.

Charting the landscape of cytoskeletal diversity in microbial eukaryotes

Ultrastructure expansion microscopy applied to 221 cultured planktonic eukaryotes maps diverse microtubule and centrin-based cytoskeletons, including dinoflagellate apical centrin rings and cryptophyte cortical centrin meshes.

Genomic diversity and functional potential of facultative bacterial symbionts across scale insects

The paper analyzes the genomic diversity and functional potential of facultative bacterial symbionts in scale insects using metagenomic data from 120 samples.

Non-photosynthetic Plastid Replacement by a Primary Plastid in the Making

The paper studies a dinoflagellate's tripartite symbiosis, showing a cyanobacterium in transition to an organelle, replacing the host's non-photosynthetic plastid.

A Midichloriaceae endosymbiont of terrestrial arthropods found as an endosymbiont in a marine nematode

This paper reports the first detection of the endosymbiont Ca. Lariskella in marine nematodes, expanding its known host range beyond terrestrial arthropods.

Shifts in Coral Reef Holobiont Communities in the High-CO2 Marine Environment of Iotorishima Island

This study examines shifts in holobiont communities of Palythoa tuberculosa under high-pCO2 conditions at Iotorishima Island, finding reduced Symbiodiniaceae diversity and altered bacterial profiles.

Accelerated pseudogenization in ancient endosymbionts of giant scale insects

The paper shows that ancient endosymbionts of giant scale insects experience accelerated pseudogenization due to genomic degradation and co-symbiont acquisitions.

Phylogenomics clarifies Balanophora evolution, plastid reduction, and obligate asexuality origins

This study uses phylogenomic analysis to clarify the evolution of Balanophora, showing independent origins of obligate apomixis and extreme plastid genome reduction linked to parasitism.

Horizontal gene transfers are widespread across termite genomes but do not confer metabolic innovations

The diversification of mealybugs was triggered by new symbiont acquisitions and followed by adaptive radiations on host plants

This study investigates how mealybugs diversified by acquiring new symbionts and adapting to different host plants.

Coral microbiomes from the Atlantic and Indo-Pacific oceans have the same alpha diversity but different composition

The paper compares coral microbiomes from the Atlantic and Indo-Pacific oceans, finding similar alpha diversity but distinct composition, with implications for symbiont phylogeny and environmental change.

Pseudofinder: detection of pseudogenes in prokaryotic genomes

Pseudofinder identifies pseudogenes in prokaryotic genomes, detecting both degraded and newly formed pseudogenes, as well as genes under relaxed selection.

Insect-symbiont gene expression in the midgut bacteriocytes of a blood-sucking parasite

The paper analyzes gene expression in the midgut bacteriocytes of a blood-sucking louse fly to understand host-symbiont interactions and finds differences in zinc usage and immunity mechanisms compared to other insects.
