Method of Making Water Stress or Salt Stress Tolerant Transgenic Cereal Plants

详细技术说明

This invention introduces a stress-inducible promoter complex that contains an ABA-response complex (ABRC) to help alleviate the problems caused by salt stress and drought stress.

*Abstract

Salt stress and drought stress cause losses of over ten billion dollars each year. This invention introduces a stress-inducible promoter complex that contains an ABA-response complex (ABRC) to help alleviate this problem. This promoter complex can be fused with a DNA molecule that increases tolerance to salt stress or water stress to create a gene cassette. Monocot plants transformed with this gene cassette exhibit increased tolerance to water stress or salt stress only when exposed to stress.

 

Potential Applications

• Desired trait genes can be expressed under water and salt stress conditions with this promoter.
• Cereal plants that can be transformed and made stress-tolerant include plants of the family Gramineae (also known as Poaceae), including rice, wheat, corn, barley, oat, sorgum, and millet.

 

Advantages

• Using an inducible promoter allows plants to grow at regular metabolic rates until it is exposed to stress, thereby conserving the plantÕs energy and resources.
• When paired with an effective protein, this promoter can dramatically increase yields and growth rates of plants grown under osmotic-stress conditions
• Decreasing the loss in crop yield caused by these stresses by even just one percent could significantly reduce the loss of money worldwide
