Phenotype of T0-generation
tomato transformants. Transformants showed dwarfed aerial part with a branching phenotype (a), modified leaf shape (b, c, d) and flower inflorescence (f) compared to WT plants (e and g) (A). Endogenous CK levels in tomatoes divided according to the chemical structure (B) and contents of bioactive CKs (C). WT: wild type; L6, L8 and L9: independently regenerated 35S::SlIPT3 transformants. Data represent means and SD of two replicates. *statistically significant difference datasets from WT (unpaired two-tailed Student’s t-test, p ≤ 0.05). **statistically significant difference from WT after Šidák correction for testing of multiple lines (multiple unpaired two-tailed Student’s t-test, overall α = 0.05, individual p ≤ 0.017).
