| AGAMOUS |
|
| AGAMOUS (AG) is a C-function floral organ identity gene, and is responsible for formation of stamens and carpels in the third and fourth whorls of the wild type flower. In addition, AG is required for meristem determinacy such that ag mutant flowers are indeterminate and produce an essentially endless number of floral whorls, repeating the basic pattern: (sepal, petal, petal)n. AG RNA begins to accumulate in stage 3 flowers in cells that will later give rise to stamens and carpels. | LINKS |
Later in flower development, AG RNA continues to develop in stamens and carpels but becomes restricted to specific cell types
