Genetically Modified Plants Having Modulated Flower Development

Inducing early flowering or sterility in plants
By controlling meristem development, the LEAFY gene has been shown to regulate flowering in diverse species. Modulation of LEAFY gene activity results in either early flower formation or suppression of flowering. The ability to induce early flowering is of great value to the agricultural and natural resources industry, as it allows both the acceleration of breeding time by shortening seed production time and the identification of new varieties. The invention relates to genetically modified plants having the phenotypic trait of early flower development. The invention also relates to methods for producing such plants and vectors for carrying out such methods. Induction of flowering is often the limiting factor for growing crop plants. The invention provides a means for inducing flowering in plants regardless of the locale or environment. This is desirable as it allows rapid cross-breeding for species selection. The present invention also provides a means for genetically modified plants with no flowering capabilities. Sterile trees or plants are desirable as they can not propagate in uncontrolled fashion.
