Fig 2. Phloem-specific expression of PaFT1 in Arabidopsis and overexpression of PaFT1 in rice drive early flowering.

A, Comparison of flowering time between transgenic plants containing pSUC2:PaFT1 and wild type plants. Thirty independent T1 plants were used for each genotype. Arrows represent the mean value of total leaf number in each genotype. P ≤ 0.0001 (Student’s t-test). B and C, PaFT1 driven by phloem-specific or shoot apex-specific promoters rescues the late flowering phenotype of Arabidopsis ft null mutant, ft-10. This activity is at least dependent on Tyr-86 residue, one of the conserved amino acids among FT proteins from various plant species. D and E, Ectopic expression of PaFT1 in rice also caused early flowering (Dongjin cultivar, grown under SD condition). Magnified panicles are shown in the box of E and flowering time data is shown in D. TLN means total leaf number.
