Flowers of California poppy (Eschscholzia californica). Two fused sepals form a hat-like structure that has already dehisced, while four free bright orange petals adorn the blossom. Inside the flower, though not visible from this perspective, are numerous stamens arranged in several whorls and a gynoecium composed of two carpels. The gynoecium is surrounded by a floral cup forming a wide rim, which can be seen on the lower left, once all other organs have fallen off. (Image credit: Annette Becker.)

AP1 floral induction system and experimental strategy used. (A) The AP1 floral induction system (pAP1::AP1-GR ap1 cal) was used in Arabidopsis. On the left, an SEM image of overproliferation inflorescence meristems of the ap1 cal mutant and on the right, an SEM image of many synchronized floral buds 5 d after dexamethasone (DEX) treatment are shown. (B) Overview of the workflow and sampling scheme. The extraction buffer Trizol was used, so from the same tissue sample, RNA and protein could be extracted. Subsequently, RNA-seq and LC-MS/MS were performed, followed by data analyses. SEM images provided by José Luis Riechmann.
