PYL13: The unique mode of action of a divergent member of the ABA-receptor protein family in drought-ABA and stress signaling

In recent years, climate change has had a noticeable effect on the global agricultural output. Changes in climate and precipitation patterns increase the likelihood of crop failures and production declines, which could leave millions without the necessary food. Because drought is a major limiting factor of plant agriculture worldwide, developing plant cultivars with improved drought resistance is important to maintain appropriate crop yields.

Purdue University researchers have identified a new gene in the Arabidopsis genus that confers drought tolerance to plants. This gene encodes a protein that can be a receptor for abscisic acid, which controls many adaptive responses of plants when under stress. Transgenic plants overexpressing this gene show increased sensitivity in seed germination, increased water-use efficiency, and enhanced drought resistance. When utilized in crop plants, this gene could help increase crop yields, especially during years with low rainfall.

Advantages:

-Enhanced drought resistance

-Increased water-use efficiency

-Increased sensitivity in seed germination

Potential Applications:

-Climate Change Research

-Farming Industry
