This chapter examines flower design features related to sexual function in pollination. Flowers show remarkable variations in shape, size, and appearance, and are known for their tendency to mass together as inflorescences.
1 sty 1999 · We examined the role of the FIL gene in the development of floral organs by constructing a set of double mutants. The flower of a plant having strong alleles of the ap2 mutant has two sepals in the abaxial and adaxial positions; however, two sepals at medial position are converted homeotically to carpels .
1 wrz 2005 · Key Points. Floral-meristem identity genes promote flower development by repressing genes that promote an inflorescence fate and activate floral-organ identity genes.
18 sty 2024 · Filament (a long stalk) The filament has an architectural function, in that it lifts the anther to a position where it can effectively release pollen grains into/onto the pollinator.
2 wrz 2019 · Flowers are unique to angiosperms. A typical flower possesses four types of organs, sepals, petals, stamens and carpels, which are arranged on the receptacle from the outside to the centre,...
1 sty 2019 · The observation that many genes regulated by the floral homeotic factors have broader functions during plant development, and that many of those genes exhibit peak expression in leaves (O'Maoileidigh et al., 2013), renewed efforts to understand how leaves are transformed into floral organs.
The development of the angiosperm flower has been an important morphological innovation in plant evolution. Through studying the molecular basis of flower development in different model species we are offered insights into the diversification of developmental networks that underly the vast array of angiosperm floral morphologies.
