Polynucleotides and polypeptides incorporated into expression vectors have been introduced into plants and were ectopically expressed. The polypeptides of the invention have been shown to confer at least one regulatory activity and confer increased yield, greater height, increased secondary rooting, more rapid germination, greater cold tolerance, greater tolerance to water deprivation, reduced stomatal conductance, altered C/N sensing, increased low N tolerance, increased low phosphorus tolerance, or increased tolerance to hyperosmotic stress as compared to the control plant as compared to a control plant.
