Effects of X‐Ray Irradiation on the Biological Parameters, Gut Microbiota, and Gene Expression of Bactrocera dorsalis: Implications for the Sterile Insect Technique

Evolutionary Applications, Volume 18, Issue 10, October 2025.
ABSTRACT The sterile insect technique (SIT), traditionally reliant on gamma irradiation, has been an effective strategy for controlling Bactrocera dorsalis. However, strict regulations governing gamma radiation sources and the limited research on the responses of B. dorsalis to X‐ray irradiation have hindered the further development of SIT.

Tracing the evolutionary pathway: on the origin of mitochondria and eukaryogenesis

The FEBS Journal, Volume 292, Issue 19, Page 5026-5041, October 2025.
This study examines the stepwise transition from archaeal–bacterial associations to the emergence of eukaryotic cells. Metabolic cooperation and endosymbiosis fostered ecological and genetic integration, with extensive gene transfer reshaping host biology.

Characterization of B Cell Responses in Rainbow Trout (Oncorhynchus Mykiss) Affected by Red Mark Syndrome

Advanced Science, Volume 12, Issue 35, September 18, 2025.
This study extensively characterizes the B cell response of rainbow trout (Oncorhynchus mykiss) in response to red mark syndrome (RMS). This disease, suspected to be caused by a Midichloria‐like organism (MLO), induces skin lesions in the infected animals, characterized by a massive influx of IgM+ B cells.

Interactions and Community Structure of Fungi and Prokaryotes in Salt and Brackish Marsh Ecosystems

Environmental DNA, Volume 7, Issue 5, September–October 2025.
Microbial communities drive biogeochemical cycling in salt and brackish marshes, yet fungal‐prokaryotic interactions remain understudied. This study used 16S and 28S rRNA metabarcoding and network analyses to examine microbial communities in North Inlet salt marsh and Winyah Bay brackish marsh.

A single-cell genome perspective on studying intracellular associations in unicellular eukaryotes. [PDF]

, 2019
Single-cell genomics (SCG) methods provide a unique opportunity to analyse whole genome information at the resolution of an individual cell. While SCG has been extensively used to investigate bacterial and archaeal genomes, the technique has been rarely ...

Daphnia‐associated bacterial communities correlate with diet quantity, environmental conditions, and epidemic size across natural outbreaks

Limnology and Oceanography, Volume 70, Issue 8, Page 2053-2066, August 2025.
Abstract Zooplankton‐associated microbiomes play an important role for host health, and contribute to ecosystem processes such as nutrient cycling. Yet, few studies have assessed how environmental gradients and biotic interactions, including parasitism and diet, may shape the microbiome composition of wild zooplankton. Here, we analyzed the microbiomes

Rickettsiales in Ticks Removed from Outdoor Workers, Southwest Georgia and Northwest Florida, USA

Emerging Infectious Diseases, 2019
We determined the prevalence of selected Rickettsiales in 362 ticks removed from outdoor workers in southwest Georgia and northwest Florida, USA. Persons submitted an average of 1.1 ticks/month.
