Class A alone specifies sepals (whorl 1), A and B together specify petals (whorl 2), B and C determine stamens (whorl 3), and C alone specifies carpels (whorl 4). In Arabidopsis thaliana, a model plant organism, mutations in these genes result in floral organs developing in incorrect positions, highlighting their crucial role in organ identity and positioning during flower formation.\n
