Plant tolerance to low water, low nitrogen and cold

摘要

Polynucleotides incorporated into nucleic acid constructs have been introduced into plants and were ectopically expressed. The encoded polypeptides of the invention have been shown to confer at least one regulatory activity and confer earlier flowering, longer floral organ retention, increased cold tolerance, greater tolerance to water deprivation, altered carbon-nitrogen balance sensing, increased low nitrogen tolerance, and/or increased tolerance to hyperosmotic stress as compared to a control plant.
