<p>The present invention relates to a method to enhance the health-promoting capacity of a plant by increasing expression of a regulatory gene product, preferably wherein said regulatory gene product is a receptor kinase, more preferably a RKS receptor or a mutein thereof or a chimeric RKS receptor. Such a method comprises providing a plant with a nucleotide sequence encoding said RKS receptor, but alternatively also a sequence encoding a truncated RKS protein can be used. Said RKS gene can be chosen from the group consisting of RKS subgroup I (RKS1, RKS4, RKS5, RKS7, RKS11, and RKS14), more specifically RKS4 and truncated RKS4 and chimeric receptors comprising the extracellular domain of RKS4. A further preferred embodiment is a method according to the invention wherein enhancing the health-promoting capacity of a plant comprises production in said plant of health-promoting substances selected from the group of polyphenols, glucosinolates, isoprenoids, and GABA and analogs, more preferably chosen from the group consisting of quercetin, kaempferol, sinapic acid, gallic acid, GABA and sinigrin. In another embodiment the invention is related to a method to produce a health-promoting substance in a plant by introducing into said plant a gene coding for a regulatory gene product, preferable a receptor kinase, more preferably an RKS gene. Further part of the invention is the use of an RKS gene for the production of health-promoting substances in a plant. Also part of the invention is a plant with an enhanced health-promoting capacity produced by the method according to the invention.</p> |
