Ectopic expression of ALF4 partially rescues the callus-forming capacity of slr roots. (A and B) qRT-PCR (A) and GUS staining (B) analyses of ALF4 expression in WT and slr roots on MS and after incubation on CIM for 6 h. n = 3. Error bars are SD. (Scale bar: 50 µm.) (C) Callus-forming phenotype (Upper) and cytological characteristic (Lower) of slr and transgenic p35S::ALF4 slr plants. Seedlings incubated on CIM for 10 d and 6 d were used for morphological and cytological characterization, respectively. (Scale bars: 1 cm in Upper, 50 µm in Lower.)
