Abstract

Genetic analyses have identified four major genetic pathways which control the timing of floral transitions in Arabidopsis. The floral promotion or inhibitory signals from these distinct pathways ultimately converge into a subset of genes, commonly known as the floral integrators, such that the plants are compelled either to switch into a flowering phase or to remain in the vegetative stage. In this review, we have discussed the recent findings regarding cross-talk between floral promotion pathways and flowering locus T and suppressor of overexpression of Constans 1, the major floral integrators within Arabidopsis. The spatial regulation of these integrators has also been discussed, as these spatial patterns may help us to understand the manner in which floral inductive signals are transmitted. We have also discussed conservation and divergence with regard to the regulation of floral integrators between Arabidopsis and rice. Finally, we have provided a series of insights into the complex signaling network which coordinates plant development.
