ALTERATION OF SEX DETERMINATION IN FLOWERING PLANTS

摘要

The invention provides methods for the production of unisexual plants. According to the invention, the plants can be either unisexual male or unisexual female plants. In the methods of the invention, the expression of the modified B Class floral identity gene results in the suppression of the development of the fourth floral whorl, which results in male-only floral development. In other methods of the invention, suppression of B Class gene expression by an altered DELLA protein results in female-only floral development in the plant.
