Fig. 4From: Engineering TATA-binding protein Spt15 to improve ethanol tolerance and production in Kluyveromyces marxianusThe central carbon metabolic network of K. marxianus. Red colored: significantly up-regulated genes for M2 vs SPT15; green colored: significantly down-regulated genes for M2 vs SPT15; grey colored: genes with no significant fold change. The log2(fold change) values of the genes are illustrated at the top-right corner. SPT15 stands for the strain overexpressing wild-type SPT15Back to article page
