Fig. 4
Several genes related to xylose fermentation were upregulated only for ethanol producers at lower oxygenation. Xylose metabolism and related pathways. Dashed lines correspond to the < -1 and > 1 confidence intervals for the log2-fold change from RNA-Seq analysis (moderate aeration/high aeration). Asterisks indicate genes that did not exhibit differential expression. Positive and negative values indicate upregulated and downregulated genes, respectively, and the colors are associated with the species as shown in the right side of the figure. Protein products encoded by each gene: HXK—hexokinase; PGI1—phosphoglucose isomerase; PFK—phosphofructokinase; FBA1—fructose 1,6-bisphosphate aldolase; TPI1—triose phosphate isomerase; TDH—glyceraldehyde-3-phosphate dehydrogenase; PGK1—3-phosphoglycerate kinase; GPM1—phosphoglycerate mutase; ENO—enolase; PYK1—pyruvate kinase; PDC1—pyruvate decarboxylase, ADH1/2—alcohol dehydrogenase; ALD6—aldehyde dehydrogenase; GPD1—glycerol-3-phosphate dehydrogenase; GPP1—glycerol-3-phosphate phosphatase; ZWF1—glucose-6-phosphate dehydrogenase; SOL—6-phosphogluconolactonase; GND1—6-phosphogluconate dehydrogenase; RKI1—ribose-5-phosphate ketol-isomerase; RPE1—d-ribulose-5-phosphate 3-epimerase; TKL1—transketolase; TAL1—transaldolase; XYL1—xylose reductase; XYL2—xylitol dehydrogenase, and XYL3—xylulokinase.
