GhFMO1 causes the activation of ROS and SA signals in tobacco. (A) H₂O₂ production in 2-week-old WT and transgenic tobacco seedlings revealed by 3,3′-diaminobenzidine staining 12h post-infiltration. (B–F) Expression of genes involved in defence responses in WT and transgenic plants detected by qPCR. Leaf samples of 4-week-old WT and transgenic tobacco grown under standard conditions were collected for RNA extraction. Gene expression levels were normalized to EF-1a expression levels.
