ABSTRACT
Flowering time is a major life-history trait that contributes to fitness in annual plants. Depending on abiotic viz., photoperiod, temperature, nutrients and biotic viz., competition, pollinators, herbivores conditions and different flowering time strategies can be adopted by different plant species. Floral induction is a key developmental switch in plants that leads to the production of flowers, fruits and seeds to meet the demands of several crop harvests per year, or the growth of crop plants in regions with short vegetation times and for the production of ornamental plants, the timing of the floral transition plays very important role. The discovery of genes that are involved in flowering time control in model plants such as Arabidopsis should allow the modulation of this developmental switch also in plants with economic value. Genetic and molecular understanding of floral transition opens new horizons for plant breeding. However, many of the current examples are restricted only to a few key regulators, although our increasing knowledge of regulatory pathways might also help to adjust flowering time in response to specific environmental challenges and to avoid unwanted pleiotropic effects. Conflicting breeding goals, such as high biomass yield and efficient seed production can be approached by new strategies.
