The tfl1 phenotype persists in plants grown under low irradiances. Plants of the WT and of the tfl1, cry1, and cry2 single, double, and triple mutants were grown under LD at the indicated irradiance. (A) Flowering time on a biological scale (leaf number). (B) Number of paraclades. (C) Number of flowers on the main shoot. (D) Length of the main stem. Data are means and SE of at least 10 replicate plants. Different lines indicate significantly different second-order polynomial fits (P < 0.01).
