WATER DEFICIT-INDUCIBLE PROMOTERS

摘要

Water deficit-inducible promoter sequences were identified that may be us ed to produce transgenic plants that are more tolerant to water deficit and related hyperosmotic stresses than control plants, and yet are wild-type or nearly wild type in appearance. Any of these water deficit-inducible promote rs may be incorporated into an expression vector that comprises a polynucleo tide regulated by one such promoter and which encodes a polypeptide that, wh en ectopically expressed, improves water deficit tolerance in plants that ar e similar to control plants in their morphology and development.
