Response of dad1-1 mutant scions to grafting over wild-type and dad2-1 mutant stocks. A, Representative 3-month-old plants of those used in the experiment. B, Height of the grafted plants (cm). C, Number of branches present on grafted plants. D, Relative expression level of DAD1 gene in basal portions of stems (close to the graft union; black bars) and roots (shaded bars) of grafted plants. Relative gene expression was normalized against expression of the three internal reference genes in each tissue sample. Data shown are ±sem (n ≥ 8 for all samples). Data are representative of two independent datasets. [See online article for color version of this figure.]
