Fig. 1

Heatmap of relative growth rate in the screening experiments with deletion mutants. The deletion mutants were cultivated with 1.0 mM coniferyl aldehyde (CFA), 10.4 mM furfural (FUR), 14.0 mM HMF, sugarcane bagasse pretreatment liquid (BPL), and spruce pretreatment liquid (SPL). The data indicate: relative growth rate < 0.5 , 0.5 ≤ relative growth rate < 0.9 , 0.9 ≤ relative growth rate ≤ 1.1 , 1.1 < relative growth rate ≤ 1.5 , and relative growth rate > 1.5 . The result with the NGG1 deletion mutant was not included in the figure, since the growth of the NGG1 deletion mutant in the SC medium was slower than that of BY4741. The numerical data for relative growth are included in Additional file 1: Table S1
