Supplemental Figure 1 Bayesian interference of AP1/SQUA-like genes.The native host and accession number of the corresponding gene are given in parentheses. MPF3, PFFUL1/2 and PFFL from Physalis fall into the three subcladesof euAP1, euFUL and FL, respectively. The maximum likelihood (ML) tree has a topology similar to that of the Bayesian tree. The supporting value for the Bayesian method above 0.90 and for ML above 50 is given for each branch. The scale at the bottom is the number (in units) of amino acid substitutions per site. The sequence alignment is presented in Supplemental Dataset 1 online.

Supplemental Figure 2 Protein-protein dimerization among MPF3-interacting partners within the yeast two-hybrid system.(A) Relative quantification of protein-protein interaction strength of MPF3-associated heterodimerization. The relative β-galactosidase activity was determined in yeast for the combination of the MPF3-associated heterodimersindicated. The experiments were performed three times. The mean and standard deviation are shown. (B) Homodimerization of proteins. Homodimerization of MPF2 was also reported by He et al. (2007). The co-transformed yeast cells were grown on SD/-Leu-His-Trp selective plates. The co-transformation of empty vectors of pGBKT7 and pGADT7 was used as negative control.

(F) A MPF3-VIGS ICS. Bar=5 mm in (A), (C), (D) and (F). Bar=1 mm in (B) and (E). (G) MPF3 was silenced via a VIGS approach. MPF3 expression was evaluated in three VIGS flowers and is indicated as V1-V3. The severe MPF3 mRNA residual in V3 was only 4.1% of wild-type (WT) flowers. (H) Expression of MPF2. (I) Expression of PFINV4. Total RNA from the indicated mutated flowers was subjected to real-time RT-PCR. Gene expression in the androecium of the WT was taken as 1, and actin was used as an internal control. The experiments were repeated thrice using three independent biological samples. Mean expression and standard deviation are shown.

Expression of PDS (black column) and PFINV4 (grey column) was investigated in P1 and P2. Total RNA from the indicated flowers was subjected to real time RT-PCR. Gene expression in the WT androecium was taken as 1, and actin was used as an internal control. The experiments were repeated three times. Mean expression and standard deviation are shown.

Supplemental Figure 8 Functional analyses in transgenic Arabidopsis.
Analysis of transgenic AP1, StMC and MPF3 in wild-type Arabidopsis. Bolting time (A) and numbers of rosette leaves (B) of a single-copy, target-inserted transgenic line were recorded under long-day (LD) and short-day (SD) conditions. More than ten plants of each line were included for analyses, and error bar is standard deviation.

a On variation, the plus indicates an increase, and the minus indicates a decrease.b Cell division (cd) index=organ size variation/cell size variation. For floral calyx, both organ and cell sizes are increased, therefore, cd index﹥1 indicates that cell division is promoted, otherwise, cell division is inhibited. For ICS, the organ size is reduced in all cases, while the cell size is either reduced or increased, therefore, 0﹤cd index﹤1 indicates that cell division is promoted, otherwise, cell division is repressed. The minus or plus in parenthesis indicates that cell division is inhibited or promoted.
