Abstract: | Plants undergo a major physiological change as they transition from vegetative growth to reproductive development. This transition
is a result of responses to various endogenous and exogenous signals that later integrate to result in flowering. Five genetically
defined pathways have been identified that control flowering. The vernalization pathway refers to the acceleration of flowering
on exposure to a long period of cold. The photoperiod pathway refers to regulation of flowering in response to day length
and quality of light perceived. The gibberellin pathway refers to the requirement of gibberellic acid for normal flowering
patterns. The autonomous pathway refers to endogenous regulators that are independent of the photoperiod and gibberellin pathways.
Most recently, an endogenous pathway that adds plant age to the control of flowering time has been described. The molecular
mechanisms of these pathways have been studied extensively in Arabidopsis
thaliana and several other flowering plants. |
