Induction with different stresses increases the number of peroxisomes in B. cinerea hyphae. a Fluorescence of B. cinerea strain GFP-SKL after incubation in 10% YEPD medium containing 0.3 mg/mL CR, 5 mM H2O2, or 10% cell-free fermentation broth of B. velezensis QSE-21 (CFB-Q). Bar = 50 μm. b, c Column charts showing hyphal length and peroxisome number. The values represent the average values, and the error bars indicate the standard deviations of 20 hyphae in one experiment. The different letters (a, b, and c) indicate significant differences at the level of P < 0.01. d Relative expression levels of 6 DEGs annotated to the peroxisome pathway via RT-qPCR analysis. BcTubulin was used as an endogenous control, and the sample collected from 10% YEPD medium at 6 hpi was used as a sample control. The values represent the average values, and the error bars indicate the standard deviations of 3 technical replicates of one experiment. *, P < 0.01
