Arabidopsisearly-flowering mutants reveal multiple levels of regulation in the vegetative-to-floral transition
The isolation and characterization of flowering time mutants should further the understanding of the developmental pathways that regulate the transition to reproductive development. Because plant development is a sequential and continuous process, the genetic analysis of floral initiation is likely to benefit from the analysis of mutations that cause pleiotropic phenotypes. This review focus on early-flowering mutants ofArabidopsisthat display additional phenotypes in either inflorescence development or light perception, and discusses the possibility that genes controlling early flower development are regulated by environmentally responsive genetic pathways.
