Abstract

Flowering process in plants is the outcome of numerous gene cascades in response to environmental and endogenous signals. Signals received in leaves are integrated at FT and the FT-mRNA moves to SAM to activate the meristem identity genes LFY and AP1. Master regulatory gene AP1 initiates a chain of reaction leading to activation of floral organ developmental genes categorized into A-E classes. Their action as directed by the meristem size and organ number genes, floral organ pattern genes and cadastral genes leads to the development of flowers with specified whorls carrying definite number of organs. This chapter has discussed the activation and suppression various genes in response to signal pathways in leaf and SAM and the gene cascades leading to flowering, with special reference to the model plant Arabidopsis.
