Flower Meristem Identity
Primary Genes: Agamous, Apetala1, Apetala2, Cauliflower, Fruitfull, Leafy, Unusual Floral Organs Henderson and Dean, 2004 UC San Diego Mizukami and Ma, 1997
Other Genes: Apetala3, Pistillata
Purpose: These genes "control the identity that a meristem will adopt. These meristem identity genes are activated in response to developmental and environmental cues ... [and are essentially the] master regulators that control the entire floral initiation process." Pidkowich et al., 1999
Floral Pathway Integrators
Primary Genes: Flowering Locus T, Leafy, Supressor of Overexpression of Constans1 Henderson and Dean, 2004
Other Genes: FD (bZIP transcription factor), Twin Sister of FT Abe et al., 2005 Yamaguchi et al., 2005
