Response of OsGRF1 and OsGIF1 to GA, ABA, and stresses. Time course analysis of expressions of OsGRF1 and OsGIF1 in response to gibberellins (GA), salt, drought, UV-light, pathogen, and ABA. 2-week-old seedlings were incubated into N6 solution containing 50 μM GA3 (a) or 200 mM NaCl (b) or 1 μM ABA (F) for designed time. 2-week-old seedlings were transplanted into 25% PEG (polyethylene glycol) (c), or exposed to 100 μmol m− 2 s− 1 ultraviolet (d), or sprayed with 3 × 105 spore ml− 1Magnaporthe grisea (e) for designated time respectively. Expression was analyzed by qRT-PCR. *, Significant difference at P < 0.05, **, Significant difference at P < 0.01 compared with No treatment by Student’s t-test (n = 3; means ± SDs)
