Expression profiles of PtrFBL genes under heat and drought treatments. (A) Heat map showing eight PtrFBL genes under heat stress. 2 h: 2 h of 37°C heat treatment; R2h: 2 h recovery after 37°C heat treatment. Endogenous IAA levels expressed in DR5-GUS plants under PEG6000 stress (B–G); (B) 0 h, (C) 0.5 h, (D) 3 h, (E) 6 h, (F) 12 h, and (G) 24 h treatments; (H,I) Expression profiles of eight PtrFBL genes under PEG6000 stress; (H) in 84k leaf; (I) in 84k stems. Bars, 1 cm (B–G), *indicates significant difference at P < 0.05.
