(A) qRT-PCR analysis and (B) expression ratios of FLM-β of FLMCol-0 (INT6+AAT) and INT6+CAA grown in 15°C and 23°C. Statistical tests of temperature-sensitivity are described in the text. (C) Means and SD of quantitative flowering time analysis (rosette leaf number). n = 5 (15°C) and 8 (23°C) replicates from five independent homozygous T3 transgenic lines grown at 15°C and 23°C in long day photoperiod. (D) Mean and SD of ratios of rosette leaf numbers from the analysis shown in (C). Student’s t-test: *p<0.05; **p≤0.01.
