Genetic Engineering for Fertility Control formation of RNase/RNase inhibitor complexes. Fertility restored anthers have a normal tapetum, and produce normal amounts of functional pollen. The hybrid system has been successfully introduced in oilseed rape, cauliflower, chicory, lettuce, tomato, cotton and corn.

Sporophytic Self-Incompatibilitynize and to reject self-pollen exclusively by physiological reactions (homomorphic SI). Population geneticists consider that the natural selection of SI early in the rise of flowering plants has been determinant for their successful espansion and domination in the present living world (Whitehouse, 1950).

Fertilization in Angiosperm Plants observations of fixed and sectioned materials (Jensen 1972; Van Went and Willemse 1984; Willemse and Van Went 1984). The embryo sac and the fertilization events taking place within it, cannot be observed directly, because it is positioned deeply inside the ovule, surrounded by a large quantity of untransparant sporophytic tissues.

The Control of Flower Formation: Exogenous and Endogenoushe roots. As a result, the various plant parts then exchange a number of signals. When the environmental conditions are favourable for flowering, this ultimately leads some target shoot meristems to shift from vegetative to reproductive growth and morphogenesis.
