Orosensory and microbiome analysis of diabetic high-lipid tasters (DHLT) and diabetic low-lipid tasters (DLLT). Panel a Orosensory perception threshold of linoleic acid (LA). b Distribution of the most abundant resolved taxa at the genus level. c Microbiota alpha diversity. d Cladogram analysis of 16S sequences from circumvallate papillae and histogram showing the taxonomic groups (P < 0.05; LDA score 2.0). e Linear regression analyses between the frequency of identified bacterial taxa and perception threshold of LA. f Cladogram derived from KEGG pathway contributions of predicted metagenomic data. The relative predicted gene count histogram shows the KEGG pathway modules (P < 0.05; LDA score 2.0). Means ± SEM, P < 0.001. M metformin, S statins (color figure online)
