Fig 6. Auxin regulates XTH9 expression in an ARF7/19-dependent manner.

Fig 6

(A) XTH9 expression level in the arf7arf19 double mutant background. RNA was isolated from 7-day-old Arabidopsis roots. (B) After treatment with 1 mM IAA for the indicated time, the wild-type (WT) and arf7arf19 double mutant roots were collected at the indicated time points. Values were determined from three independent plant roots. The auxin-dependent repression of XTH9 expression in the roots is ARF7/19 dependent. (C) Relative length of lateral root per 1 cm of primary root and (D) XTH9 expression levels in the WT, arf7arf19-1 and arf7arf19-1 & 35S::XTH9 transgenic plants. *indicates significant differences (p<0.05). The error bars represent SDs (n = 3).
