Figure 1. Protein interactions among FTs and FDs.
(A) Structure of AtFD, AtFDP from Arabidopsis and OsFD1 from rice. bZIP domains are marked with yellow boxes. (B) AtFD and AtFDP are able to interact with rice phosphatidylethanolamine-binding protein (PEBP) family proteins as well as AtFT in yeast cells. (C) Positive interactions in the yeast system between AtFD/AtFDP and rice proteins Hd3a and RFT1 were verified in rice protoplasts by BiFC assays. Scale bars = 5 μm.
