Abstract
Official abstract text for this publication.
The invention provides methods for improving plant yield, particularly under nitrogen limiting conditions. According to the invention, applicants have discovered that modulating ACC synthase activity in plants improves yield of plants, even when grown under low nitrogen conditions. The same plants, while demonstrating improved yield over non-modified plants, exhibited no deleterious effects under normal nitrogen conditions. The invention further provides methods using recombinant expression cassettes, host cells and transgenic plants.
First claim
Opening claim text (preview).
That which is claimed: 1. A method of improving nitrogen stress tolerance in a maize plant comprising: a) inhibiting ethylene synthesis in a plant by introducing into a maize plant a heterologous polynucleotide that reduces the activity of 1-aminocyclopropane-1-carboxcylic acid (ACC) synthase 6 (ACS6) upon expression of said heterologous polynucleotide; wherein said heterologous polynucleotide comprises a nucleic acid selected from the group consisting of: i) a nucleic acid co…
