One of the four whorls in the structures formed during this process is called the stamen, which contains filaments that attach the pollen-producing anther to the stem.
The FRIGIDA complex recruits chromatin modification factors to activate the expression of FLC, an inhibitor to this process. Phytochromes and cryptochromes act as light receptors to the CONSTANS gene, whose expression signals other genes like FT to begin this process. In one model of this process, cadastral genes regulate the action of organ-identity transcription factors in the MADS-box family, which determine the order of the primordium. The photoperiodic and (*) vernalization pathways send signals from the phloem to the shoot apical meristem during this process, which is described by the ABC model. One of the four whorls in the structures formed during this process is called the stamen, which contains filaments that attach the pollen-producing anther to the stem. For 10 points, name this process in which an angiosperm produces a reproductive structure with petals.
