Fuente: WIPO "tomato" The present application relates to compositions comprising one or more elicitor proteins, polypeptides, or peptides that induce defense responses in plants, thereby enhancing resistance to biotic and abiotic stress and promoting growth. These compositions can be applied to seeds, plants, or soil to improve crop performance and yield. The invention further includes transgenic plants expressing nucleic acids encoding elicitor proteins. It further discloses methods for controlling plague infestation improving the yield of a plant by applying the composition comprising the elicitor protein.
