abiotic stress tolerance enhancement method in an agricultural crop plant, transgenic corn plant, plant cell, seed, method of down regulation of an endogenous acc oxidase gene in a corn plant.

摘要

Compositions and methods reduce the expression of endogenous ACC oxidase genes to improve an agronomic characteristic of a crop plant, which may be maize. Yield increase and drought tolerance due to reduction in the endogenous ACC oxidase levels are observed. ACC oxidase genes are identified in maize, rice, and Arabidopsis genomes.
