Figure Lengend Snippet: Transcriptome and metabolome of Pantoea sp. Nvir growing on M9 mineral medium with 100 µM NPA. (A) Pantoea sp. Nvir differential gene expression profile under growth with and without NPA. Pantoea was cultured in an M9 mineral salt medium supplemented with 100 µM NPA or an equimolar concentration of glycerol (control). Samples for RNA extraction (biological triplicates) were taken 2 h after NPA/glycerol supplementation. A heatmap shows differential gene expression (log 2 fold change; cutoff = 2; P < .05) in Pantoea cultures. (B) Mirror plot of observed MS2 feature (top), and MS2 of a commercially purchased 2-isopropylmalic acid standard (bottom) analysed under the same experimental parameters with LC-qToF-MS. (C) Simplified l -leucine biosynthesis pathway with chemical structures and corresponding chromatograms at 6 h after NPA or glycerol (control) supplementation. 3-hydroxy-3-methyl-2-oxobutanoate and 2-oxoisovalerate were putatively identified based on m/z value (in italics), whereas 2-isopropylmalate and leucine/isoleucine were identified using chemical standards. Data are represented as the mean of biological quadruplicates.
