Viral communities in millipede guts: Insights into the diversity and potential role in modulating the microbiome

Popis výsledku v původním jazyce

Millipedes are important detritivores harbouring a diverse microbiome. Previous research focused on bacterial and archaeal diversity, while the virome remained neglected. We elucidated the DNA and RNA viral diversity in the hindguts of two model millipede species with distinct microbiomes: the tropical Epibolus pulchripes (methanogenic, dominated by Bacillota) and the temperate Glomeris connexa (non-methanogenic, dominated by Pseudomonadota). Based on metagenomic and metatranscriptomic assembled viral genomes, the viral communities differed markedly and preferentially infected the most abundant prokaryotic taxa. The majority of DNA viruses were Caudoviricetes (dsDNA), Cirlivirales (ssDNA) and Microviridae (ssDNA), while RNA viruses consisted of Leviviricetes (ssRNA), Potyviridae (ssRNA) and Eukaryotic viruses. A high abundance of subtypes I-C, I-B and II-C CRISPR-Cas systems was found, primarily from Pseudomonadota, Bacteroidota and Bacillota. In addition, auxiliary metabolic genes that modulate chitin degradation, vitamins and amino acid biosynthesis and sulphur metabolism were also detected. Lastly, we found low virus-to-microbe-ratios and a prevalence of lysogenic viruses, supporting a Piggyback-the-Winner dynamic in both hosts.
