Abstract
Water deficit-inducible promoter sequences were identified that may be used 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 promoters may be incorporated into an expression vector that comprises a polynucleotide regulated by one such promoter and which encodes a polypeptide that, when ectopically expressed, improves water deficit tolerance in plants that are similar to control plants in their morphology and development.
