Fig. 6: Partial floral development phenotypes of targeted deletion plants.

a–c Wild-type Arabidopsis. d–f AP1 mutants with strong branching characteristics and doubled or tripled carpels fused together. g–i SVP mutants with increased branching and obvious fourth-order branching showed decreased fruit number and floral abortion. j–l TFL1 mutants with dwarf determinate inflorescences, doubled carpels and increased petal numbers. m–o The floral development of the triple-gene mutant with aborted determinate inflorescences. All plants were grown for 40 days
