Protein localization, binding and regulation abilities of EjRAVs on FT and SOC1 homologs in loquat. (A) Subcellular localization of EjRAV1/2 proteins expressed in tobacco epidermal cells. (B) EjRAV1/2 regulation on EjFTs and EjSOC1s expressions in N. benthamiana leaves by using the dual-luciferase (LUC) system. Relative renilla (REN) luciferase activity was used as an internal control. Data represent means ± standard error from three replicates. **P < 0.01 and NS indicate significance and non-significance, respectively. (C,D) Binding ability of EjRAV1 to P1 of EjFT1 promoter in EMSA assays. P1, P2, P3, P4, and P5 are presumptive RAV protein binding sites on promoter of EjFT1 at (−1583 to −1579 bp), (−1059 to −1054 bp), (−1033 to −1029 bp), (−782 to −778 bp), and (−73 to −66 bp). Unlabeled probe could reduce binding ability of EjRAV1 to P1 in (D). (E) Binding ability of EjRAV1 and EjRAV2 to segment3 (−1118 to −994 bp) of EjFT2 promoter in Y1H assays.
