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.
Which of the above statements are true?
