Analysis of the tripartite interactions between two bacterial symbionts, a novel <i>Solitalea</i>-like bacterium (Bacteroidota) and <i>Cardinium</i>, and the stored product mite <i>Tyrophagus putrescentiae</i> based on gene expression data.

ABSTRACT: The intracellular parasite Cardinium influences the bacterial microbiome composition of arthropod hosts; however, the mechanisms involved remain poorly understood. We sought to evaluate the interactions between Cardinium (cTPut) and SOL in Tyrophagus putrescentiae cultures based on relative abundance and gene expression data. First, we assembled the genome of Candidatus Krakonobacterium acarorum (formerly the Soliltalea-like symbiont SOL), a novel lineage of the Bacteroidota symbiont of mites. The assemblage SOL genome (1.2 Mb) contained complete pathways for the biosynthesis of lipoic acids, pantothenate, and menaquinone from futalosine. SOL is considered a facultative inhabitant (with prevalences ranging from 36% to 80% among individuals) of the gut (fr
