Summary: Many insects rely on intracellular bacterial symbionts to supplement their specialized diets; hosts have tight control over the density of their intracellular bacterial partners, regulating through physical compartmentalization and autophagy.

Summary: This study examines the (co)evolution of host-associated microbiomes and finds that microbial and host fitness tend to trade-off rather than generating conflict. The results highlight the importance of quantifying microbial relative fitness for understanding microbiome evolution and improving host fitness.

Summary: Research shows that Wolbachia infection in insect host cabbage root fly significantly reduces microbial diversity, alters structure and composition, decreasing some taxa while increasing others. Wolbachia infection negatively correlates with certain bacterial genera, impacting the host's microbiota and extended phenotype.

Summary: This study focuses on the bacterial communities associated with cultured strains of 5 Ostreobium clades using 16S rRNA sequencing. The research reveals the preferential associations between Ostreobium and 34 bacterial taxa, which are also present in their natural environment. The study also shows a significant congruence between the Ostreobium phylogeny and the community composition of its tightly associated microbiome.

Summary: Analysing the diversification dynamics of the subphylum Glomeromycotina, the microscopic arbuscular mycorrhizal fungi that have been symbiotically associated with land plants for millions of years, this study reveals that they have low speciation rates compared to other eukaryotes. After a peak of speciation between 200 and 100 million years ago, a decline in speciation rates is observed, possibly due to a shrinking mycorrhizal niche and limited ability to colonize new niches.

Summary: The study aimed to investigate the host specificity of the cotton-melon aphid and whether bacterial symbionts control the host specificity. The results showed that the host specificity of the cotton-melon aphid is not controlled by specific bacterial symbionts or by Buchnera abundance.

Summary: The research investigated the membership criteria and persistence of a multitrophic insect symbiont community in host inflorescences. It found that the services provided by mutualistic symbionts can affect the community structure and function, with hosts exhibiting feedback by aborting inflorescences not pollinated by mutualistic symbionts.

Summary: Host genetic variation can influence the diversity and composition of associated microbiomes, with potential reciprocal effects on host traits and performance. This study investigated the genetic basis of host effects on rhizosphere bacterial composition in switchgrass, a grass species with substantial diversity. The findings revealed that different genotypes of switchgrass had different rhizosphere bacterial diversity and composition, and some bacterial families showed heritability in their relative abundance. A genome-wide association study identified single-nucleotide polymorphisms associated with bacterial composition. These results highlight the influence of switchgrass genomic and life-history variation on rhizosphere bacterial composition.

Summary: Anaplasma phagocytophilum exploits multivesicular body biogenesis and trafficking to benefit various stages of its intracellular infection cycle. This bacterium causes granulocytic anaplasmosis, a globally emerging zoonotic disease with limited antibiotic treatment options.

Summary: In a systematic comparison of 28 host gene expression signatures, differences in performance were observed based on signature size and characteristics of the validation population, such as age and infection type. It was noted that differential performance in specific populations may only be observable through this type of large-scale validation.

Summary: This study conducted a systematic review to evaluate the performance of host genomic biomarkers in the diagnosis of bacterial infection. The results showed that host genomic biomarkers have high sensitivity and specificity for bacterial infection, indicating their potential clinical utility, but further validation is needed before clinical implementation.

Summary: This research reveals the reproductive mechanism of a cube-like gammaproteobacterium called Candidatus Thiosymbion cuboideus on marine nematodes. The study shows that the symbiont cells are host-polarized and the tubulin homolog FtsZ plays a significant role in the division process.

Summary: The study found that there is a biosynthetic loop of arginine-citrulline in sponge larval holobiont, where symbionts can synthesize arginine and larvae can convert arginine from seawater into NO and citrulline. The results support the holobiont complementation of the arginine-citrulline loop and NO biosynthesis in Amphimedon larvae, suggesting a critical role for bacterial symbionts in sponge development.

Summary: Microscopic symbionts, such as feather mites, pose challenges in high-throughput sequencing (HTS) studies due to their small size and minimal DNA yields. This study used a strategic Pool-Seq approach to overcome these challenges and assess genetic diversity in feather mites. The results showed that samples containing multiple mites had more sequencing reads mapping to the mite reference genome than samples with only a single mite. The genetic structure of mite infrapopulations was primarily determined by individual hosts, indicating evolutionary processes at the infrapopulation level. This work highlights the importance of both individual-level and infrapopulation-level sequencing in understanding host-symbiont coevolution.
