The invention discloses a transgenic method for enhancing sink strength in female reproductive organs. It involves the temporal and spatial expression of genes affecting the starch and sucrose metabolic pathways in a plant organ or plant tissue. The invention also includes expression constructs, and methods for the production of crop plants with heritable phenotypes which are useful in breeding programs designed to increase yield potential over a range of environmental conditions.

Enhanced floral sink strength and increased stability of seed set in plants

The invention provides methods for enhancing maize silk exsertion under stress conditions and compositions relating to such methods, including nucleic acids and proteins. The invention further provides recombinant expression cassettes, host cells, and transgenic plants.

Enhanced silk exsertion under stress

The invention discloses a transgenic method for enhancing sink strength in female reproductive organs. It involves the expression of nucleic acids encoding acid invertase or ADP-glucose pyrophosphorylase floral tissue. The invention also includes expression constructs used in the method.
