GWAS validation. Effect of microbiota on nutritional indices in fly lines with mutations in GWA-predicted genes for each of (a) TAG, (b) glucose, and (c) glycogen. Ratio refers to the ratio of the gnotobiotic:axenic index value in the mutant relative to the ratio of the gnotobiotic:axenic index value in the background Drosophila stock. Statistical differences (mixed-effects linear models) between the mutant and its background were calculated under each microbiota treatment (axenic and gnotobiotic), and an effect was assigned where mutant and background stocks were significantly different under only one microbiota treatment (indicated by *).
