A transgenic plant transformed by a GTP Binding Stress-Related Protein
(GBSRP) coding nucleic acid, wherein expression of the nucleic acid
sequence in the plant results in increased tolerance to environmental
stress as compared to a wild type variety of the plant. Also provided are
agricultural products, including seeds, produced by the transgenic
plants. Also provided are isolated GBSRPs, and isolated nucleic acid
coding GBSRPs, and vectors and host cells containing the latter.
