Using Vacuolar Na+/H+ Antiporters to Increase Salt Tolerance in Plants

Tech ID: 32143 / UC Case 2002-502-0

Abstract

Researchers at the University of California, Davis have developed a method that increases salt tolerance in plants. This method introduces a polynucleotide that encodes a Na+/H+ transporter polypeptide.

Full Description

Environmental stressors and reduced crop productivity resulting from soil salinity affect crop yields globally. Increasingly, extreme weather patterns and concerns over global water usage require crops to thrive in higher-salt soils. Conserving water by increasing the use of recycled or reclaimed water for crop irrigation also tends to increase water salinity and mineral content – further exacerbating the problem. However, previous attempts to mitigate soil salinity problems all have major limitations. One alternate approach – Traditional breeding of crops to tolerate a more saline growing environment has not demonstrated consistent success either. Thus, new solutions are required.

Researchers at the University of California have developed a method for enhancing salt tolerance in plants via a polynucleotide that encodes a Na+/H+ transporter polypeptide. The overexpression of a gene that encodes this vacuolar Na+/H+ antiporter has been shown to enhance the salt tolerance of transgenic plants. This approach will enable agricultural crops to tolerate higher-salt soils and environments. Widespread application of this innovation would both increase lands suitable for a wider array of crops and broaden the options available for irrigating agricultural lands.

Applications

  • Enhance a plant’s ability to tolerate soil salinity

 

Features/Benefits

  • More cost-effective and widely applicable than alternate solutions
  • Decreases the negative effects of soil salinity on crop productivity
