OsFPFL4 increases auxin accumulation in the shoots and roots via coordinated auxin biosynthesis, transport and degradation. a and b Quantification of auxin content in the 9-day-old shoots and roots, respectively. Data are means ± SE (n = 10). Relative transcription levels of the genes involved in auxin biosynthesis (c), transport (d and e), and degradation (f). Data are means ± SE (n = 3). Three replica experiments were performed. WT, wild type. OE-5 and OE-9, OsFPFL4 overexpression transgenic lines. RNAi-3 and RNAi-8, OsFPFL4-RNAi transgenic lines. The significant difference between OsFPFL4 transgenic lines and wild type was determined by Student’s t-test. ^*p < 0.05, ^**p < 0.01. All data displayed as a mean ± SD. Three independent experiments were performed (n = 30 plants per genotype in each independent experiment)
