Possible ethanol consumption routes in K. marxianus. In this figure, ethanol is consumed both in the cytoplasm (the upper part) and mitochondria (the lower part). Blue–gray rectangle denotes the involved gene, and Groups ①, ②, ③, ④, ⑤, ⑥, and ⑦ are in line with those definitions in Fig. 2. Red and green in group number denote gene’s up- and down-regulation, respectively. Color’s intensity represents the degree of gene expression change, the correspondence of color and log₂ratio value is quantified by the color bar in figure’s top left corner
