ult1-3 represses LFYasEMF1 early flowering and abnormal flower phenotypes. A and B, Flowering times of wild-type (WT), LFYasEMF1, ult1-3, and LFYasEMF1 ult1-3 plants, measured as rosette leaf number (A) during LD and SD growing conditions in soil and cauline leaf number (B) during LD growing conditions in soil after 15 d on agar plates grown under SD conditions. Error bars represent se. Asterisks indicate values that are significantly different from the wild type (**P < 0.01 using Student’s t test). C, A wild-type inflorescence apex. D, A LFYasEMF1 inflorescence apex bearing abnormal flowers and a terminal flower (TF). E, An ult1-3 inflorescence apex that generated flowers containing additional floral organs. The inset shows the extra petal in an ult1-3 flower. F, A LFYasEMF1 ult1-3 inflorescence apex that is normal. G, A wild-type flower with four petals, four sepals, six stamens, and two carpels. H, A LFYasEMF1 flower with four curly petals, four curly sepals, four curly stamens, and two carpels forming a twisted pistil. I, An ult1-3 flower with six sepals, six petals, six stamens, and two carpels. J, A LFYasEMF1 ult1-3 flower with four normal petals and sepals, six stamens, and two carpels. K to N, Siliques from wild-type (K), LFYasEMF1 (L), ult1-3 (M), and LFYasEMF1 ult1-3 (N) plants.
