FIGURE 3.

Phyllody‐inducing activity differs among phyllogen groups. (a) and (b) Floral phenotypes of Arabidopsis thaliana plants infected with the tobacco rattle virus (TRV) vector carrying phyllogens belonging to either the phyl‐A, ‐C, or ‐D group (a) or the phyl‐B group (b). Phyllody‐like phenotypes consisted of leaf‐like sepals (se), leaf‐like petals (pe), leaf‐like stamens (st), and a stem‐like pistil (pi). (c) Confirmation of the infection and insertion stability of the TRV vector by reverse transcription (RT)‐PCR. RT‐PCR was performed with primers flanking the site of insertion in RNA2 of the virus about 30 days after inoculation in A. thaliana plants. (d) Floral phenotypes of the phyl‐B group‐ and α‐helix truncated phyllogen (phyl‐A: PHYL1_PYR)‐overexpressing transgenic A. thaliana plants
