Following statements regarding to the classes of genes that regulate floral development:

A. Floral organ identity genes directly control floral identity. The proteins encoded by these genes are transcription factors that likely control the expression of other genes whose products are involved in the formation and/or function of floral organs.

B. Cadastral genes act as spatial regulators of the floral organ identity genes by setting boundaries for their expression.

C. Meristem identity genes are necessary for the initial induction of the organ identity genes. These genes are the positive regulators of floral organ identity.

D. Cadastral genes act as negative regulators of the floral organ identity genes by inhibits their expression.

E. Meristem identity genes are the negative regulators of floral organ identity genes.
