FLC expression under the control of heterologous promoters results in delayed flowering. (A) Flowering time measurement of F1 plants of promoter:LhG4 × LhGh/pOp-FLC/GUS in Ler (red bars) and the corresponding promoter:LhG4 line in Ler (black bars), with the promoter indicated on the x axis. The standard errors are indicated. (B, E, H, K, and N) Ovules containing heart-stage embryos. (C, F, I, L, and O) Dissected bent-cotyledon-stage embryos. (D, G, J, M, and P) Ten-day-old vegetative plants. The promoter driving FLC and GUS expression is indicated at the top. (Scale bars: 100 μm.)
