Patterns and determinants of the global herbivorous mycobiome

Abstract: In spite of their indispensable role in host nutrition, the anaerobic gut fungal (AGF) component of the herbivorous gut microbiome remains poorly characterized. To examine global patterns and determinants of AGF diversity, we generated and analyzed an amplicon dataset from 661 fecal samples from 34 animal species, 9 families, and 6 continents. We identified 56 novel genera, greatly expanding AGF diversity beyond current estimates. Both stochastic (homogenizing dispersal and drift) and deterministic (homogenizi… Show more

“…Interestingly, some of these genera, e.g. Khoyollomyces, AL3, have previously been shown to associate with non-ruminant hindgut fermenters [37]. The most notable decrease in relative abundance during pre-weaning to post-weaning transition was observed for the genus Khoyollomyces , with average relative abundance 32.49 ± 5.19% on day 1, decreasing to an average of 0.41 ± 0.02% in the post-weaning phase ( Khoyollomyces was completely absent from the post-weaning samples at day 180, 300, ad 360).…”

“…Pooled samples were sequenced at the University of Oklahoma Clinical Genomics Facility using the MiSeq platform. Protocols for read assembly, and sequence quality trimming are described elsewhere [37]. Sequences were assigned to AGF genera as described previously [20, 37].…”
