1. ULT1 and UIF1 control floral organ number in the same pathway.
ULT1 and UIF1 control floral organ number in the same pathway. (A-P) Phenotypes of uif1-3 ult1-3 double and single mutants, including additional sepals (white arrows in E,I,M); pistils (P) with locules (asterisks in D,H,L,P); branching stamens (red arrows in K,O). Scale bars: 1 mm. (Q-S) Graphs showing percentage of flowers with supernumerary floral organs. (Q,R) Percentage of flowers carrying from four to eight sepals (Q) or petals (R), and two or three locules (S), counted from 300 flowers per line. Error bars represent s.d. χ2 tests showed that each of the uif1 ult1, uif1 and ult1 populations was homogeneous (α-level=0.05) and that there was no significant difference between uif1 ult1 and ult1 mutants for additional floral organs (α-level=0.02 for sepal or petal number; for locule number).
