Effects of different brewing materials and spatial locations on the dominant genera of eukaryotic microbiota in pit mud. (A) Heatmap profile shows the relative abundance of dominant genera and difference among groups; (B) Boxplot shows the difference of relative abundance of Aspergillus fumigatus; (C) Boxplot shows the difference of relative abundance of Aspergillus sp.; (D) Boxplot shows the difference of relative abundance of Brettanomyces custersianus; (E) Boxplot shows the difference of relative abundance of Debaryomyces sp.; (F) Boxplot shows the difference of relative abundance of Naganishia sp.; (G) Boxplot shows the difference of relative abundance of Penicillium chrysogenum; (H) Boxplot shows the difference of relative abundance of Pichia fermentans; (I) Boxplot shows the difference of relative abundance of Pichia sp.; (J) Boxplot shows the difference of relative abundance of Saccharomycopsis selenospora; (K) Boxplot shows the difference of relative abundance of Saccharomyces cerevisiae; (L) Boxplot shows the difference of relative abundance of Saccharomycopsis fibuligera. M3GUL, the pit mud sample was collected at the upper layer (0.5 m below the cellar surface) of the three-grain Baijiu brewing pit. M3GML, the pit mud sample was collected at the middle layer (1.3 m below the cellar surface) of the three-grain Baijiu brewing pit. M3GBL, the pit mud sample was collected at the bottom of the three-grain Baijiu brewing pit. M5GUL, the pit mud sample was collected at the upper layer of the five-grain Baijiu brewing pit. M5GML, the pit mud sample was collected at the middle layer of the five-grain Baijiu brewing pit. M5GBL, the pit mud sample was collected at the bottom of the five-grain Baijiu brewing pit. * p < 0.05; ** p < 0.01; *** p < 0.001.
