Jan 1, 2025 · Our study specifically identified keystone OTUs for the co-occurrence networks of soil bacterial and fungal communities across karst forest succession. These key OTUs were designated as the nodes that rank among the top 1% in terms of node degree values within each respective network.

Sep 19, 2017 · The present study allowed to recognize key OTUs that were potentially relevant to discriminate the geographic origin of the fish being surveyed.

May 17, 2024 · Network showing the relationship of microbial OTUs to the root exudate compounds and the effect of long-term continuous cropping on the abundance of key OTUs and key compounds in the network.

Mar 1, 2025 · To identify key taxa mediating interactions among the functional communities, partial Mantel analysis was performed. This analysis identified a total of 2663 OTUs, termed linker OTUs, whose abundance distributions were significantly associated with the structure of other functional communities.

The importance of an OTU was determined based on the mean decrease in accuracy of discrimination, and OTUs with a value greater than 0.003 were considered key OTUs.

In this paper, we propose a hierarchical structural component model for microbiome data (HisCoM-microb) using taxonomy information as well as OTU table data. The proposed HisCoM-microb consists of two layers: one for OTUs and the other for taxa at the higher taxonomy level.

Mar 1, 2025 · Results from structural equation model illustrating the mechanism of synthetic microbial community inoculation on lignocellulose degradation via lignocellulose degradation, hydrolase enzymes, fungal community composition, fungal diversity, and key OTUs.

Jun 13, 2024 · In this study, potential key OTUs from Massilia (OTU44), Flavisolibacter (OTU2396), Brevundimonas (OTU632) and Pseudomonas (OTU731) related to disease suppression were identified using multiple methods.
