Gene expression cross-profiling in genetically modified industrial Saccharomyces cerevisiae strains during high-temperature ethanol production from xylose

► Strains able to consume xylose at high fermentation temperature were constructed. ► Genes related to the integrity of cell walls and carbohydrate metabolism were regulated. ► Up-regulation of stress-related genes indicates cross-protection in the cells. ► This is the first gene profiling for xylose fermenting strain at 38 °C.
