3.2 | The characteristics of SNMs gut microbes
Based on the taxonomical profiles, Firmicutes and Bacteroidetes were the
two main phyla (Figure 2b), and Clostridium and Prevotellawere the dominant genera (Figure 2c) in the RGC. Additionally, we
identified a common set of 241 non-redundant genes, 4032 COGs, 624
genera, 45 phyla, 3018 KOs and 191 CAZy families shared by all 143
individuals (Figure 2d; Table S7), suggesting the existence of a core
set of genes, microbial composition and functions in the gut microbes of
SNMs.
To assess the extent to which our gene catalogue represents the
diversity of the gut microbiome in SNMs, we mapped published data
generated from 10 fecal individual samples of wild Sichuan SNM to the
RGC. On average, 76.55% of the reads mapped to our gene catalogue
(Table S8). The mapping rate was similar to that of SNMs in our study
(Table S2), indicating that the RGC should represent the characteristics
of the gut microbiome in SNMs. Furthermore, we also mapped 10 fecal
individual samples of captive Sichuan SNM to the RGC, and the average
mapping rate was 49.83% (Table S 8), indicating that captive
environment has a significant effect on the structure of gut microbiome
in SNMs.
