Engineering Crassulacean Acid Metabolism to Improve Water-Use Efficiency

Description:

 

Background:

This is a novel method for genetic engineering of Crassulacean Acid Metabolism (CAM) in plants. CAM is

a specialized form of photosynthesis that reduces relative crop water demand five-to-six fold compared with non-CAM

plant species. This adaptation saves water by shifting atmospheric CO2 uptake from the day, when the plant loses a high

amount of water, to night when transpirational water losses are much reduced, resulting in greater water-use efficiency

and improved drought tolerance. This nocturnal CO2 uptake can also improve the overall carbon budget of the plant

resulting in improved growth. These innovations are critical as there is a great need to increase global food production and

improved plant drought tolerance in the face of global climate change.
