METHODS OF INDUCING UNREDUCED APOSPOROUS OR DIPLOSPOROUS EMBRYO SAC FORMATION IN A SEXUAL ANGIOSPERM
Abstract: The present invention discloses wild type genes that upon their down regulation unequivocally induce AES formation in sexual plants. Photomicrographs of apospory in the down regulated germplasm meet all four criteria. The identified genes and methods may be used as part of a genetic engineering strategy to convert sexual crops to apomixis, which will reduce costs of hybrid seed production for crops currently grown as hybrids and will allow crops currently grown as inbred varieties, due to prohibitively high hybrid seed production costs, to be grown as superior yielding hybrids. The disclosure concerns methods of inducing unreduced aposporous or diplosporous embryo sac formation in a sexual angiosperm comprising modifying the expression level of one or more genes.
