Drought-Tolerant Plants and Methods of Increasing Drought Tolerance in Plants

Reference Number: 00-14

Inventors: Xuemin Wang and Yongming Sang


More than 90% of the water loss in terrestrial plants is through pores, called stomata, which are located in the epidermis of the plant’s leaves. Selective regulation and modification of stomatal closure would contribute to the development of drought resistant plants, plants with modified rates of respiration, transpiration, and bioremediation, and plants which react to drought stress in a quicker, more efficient manner.

  • Methods of altering drought response in plants
  • Genetically altered plants with modified stomatal responses
  • Methods of select for plants which have upregulated or down regulated stomatal closure
  • Methods to test plants for stomatal closure
  • Methods to distinguish between wild-type and genetically altered plants
Patent Status
  • U.S. Patent #6,756,526 issued on June 29, 2004
