Fig. 1. Antagonistic effect of 35S::CO and 35S::FLC on flowering time, floral morphology, and expression of SOC1 and FT. (A) Phenotype of wild-type (WT), 35S::CO, 35S::CO 35S::FLC, and 35S::FLC plants. (a) Thirty-two-day-old plants grown in LDs; (b– f) morphology of siliques; (g) dissection of silique in (f) to show an ectopic inflorescence. (B) Northern analysis of SOC1 and FT mRNA in WT, 35S::CO, 35S::CO 35S::FLC, and 35S::FLC plants. One filter made with RNA harvested 8 h after dawn was hybridized with probes for SOC1 and UBQ10 (upper rows). A second filter made with RNA harvested 16 h after dawn was sequentially hybridized with probes for FT and UBQ10 (lower rows).
