A change in gene expression in the shoot apex that leads to the development of flowers, the reproductive organs of angiospermophytes (flowering plants)
Flower development
1. Enlargement of the shoot apical meristem
2. Differentiation to form sepals, petals, stamen and pistil
Flowering plants
Typically come into bloom when a suitable pollinator is most abundant
Photoperiodism
The most common trigger for a change in gene expression leading to flowering, involving day/night length
