Abstract:
Efficient use of water in agricultural production is one of the great challenges of the 21st Century, as agriculture currently is responsible for ~70% of freshwater
consumption. Benefits of improving water utilization efficiency in agriculture are expected to include reduced water consumption, environmental sustainability, and improved yields in water limited environments. Yield improvements through
tolerance to water deficits that occur periodically in the Central Corn Belt and frequently in western states are important challenges in the coming decade.
Transgenic approaches using model systems are adding to our understanding of plant pathways that are important to water use efficiency. Genes identified using model systems have been shown to improve important drought tolerance
phenotypes in maize. This presentation will provide an overview of current
greenhouse and field based programs focused on the discovery and development of genes used for the improvement of drought stress tolerance in Maize.
