Organ identity genes Notes:
A great deal of attention has focused on the genes that specify organ identity, leading to the "ABC" model of flower development. This model proposes that at around the time of organ initiation, the flower meristem is partitioned into three overlapping fields of gene activity, with each field defining two adjacent whorls. These Organ identity genes directly control organ identity and also code for transcription factors that control the expression of other genes, whose products are implicated in the formation or function of the distinct organs of the flower.
