Tf promotes leaf complexity and axillary bud formation. (A and B) Leaf phenotype of tf-z (A) and a transgenic plant harboring a Tf:Tf construct (B). (C) Comparison of axillary shoot formation in tf-z and seven independent transgenic plants harboring a Tf:Tf construct. (D) Leaflet formation in leaf 1 (L1) to leaf 7 (L7) of seven independent transgenic plants (blue bars) containing the Tf:Tf construct in comparison with the tf-z mutant (yellow bar). (E) Comparison of leaf phenotype of a WT plant (MM) and a primary transgenic plant harboring the 35S:Tf construct (MM 35:Tf). (F) Leaflet formation in the fifth leaf of five independent transgenic plants (blue bars) in comparison with the MM WT (yellow bar). Numbers of primary, secondary, tertiary, and intercalary leaflets are shown. In MM, no tertiary leaflets were formed. (Scale bar: A and B, 2 cm.)
