In planta tumorigenesis assays in wild‐type (WT) AC⁺ and hp1 mutant plants. (A) Tumours formed on stems of WT AC⁺ and hp1 mutant plants inoculated with the tumorigenic strain Agrobacterium tumefaciens A348. The photographs of the stems with tumours were taken 4 weeks after inoculation. (B, C) Quantification of the biomass of the tumours. The fresh and dry weights of the tumours developed on the stems of WT AC⁺ and hp1 mutant plants were measured 4 weeks after inoculation. The experiments were repeated twice with at least six samples. Error bars indicate standard deviation. The statistical significance of the difference was confirmed by Student's t‐test (**P < 0.01).
