Bioactive priming polypeptides are provided that are useful when applied to plants in agricultural formulations. Methods of using the formulations containing the bioactive priming polypeptides are also provided which are applied exogenously to the surface of a plant or a plant cell membrane or endogenously to the interior of a plant or to a plant cell. The bioactive priming polypeptides when applied to a plant, a plant part, or a plant growth medium or a rhizosphere in an area surrounding the plant or the plant part increase growth, yield, health, longevity, productivity, and/or vigor of a plant or a plant part and/or decrease abiotic stress in the plant or the plant part and/or protect the plant or the plant part from disease, insects and/or nematodes, and/or increase the innate immune response of the plant or the plant part and/or change plant architecture.
