  • Transgenic fodder plants with an increased leaf starch content
    Publication number: 20030217386
    Abstract: There is described a method for generating transgenic fodder plants which are genetically modified, where the genetic modification leads to a reduced activity of an R1 protein in comparison to corresponding wild-type plants which have not been genetically modified. Such transgenic fodder plants are distinguished by their substantially increased leaf starch content in comparison with wild-type plants.
