  • Method for determining the level of zygosity of a seed
    Patent number: 11668703
    Abstract: The invention relates to a method for determining the level of transgene zygosity in a poaceae seed, the transgene being genetically linked to a gene coding for a fluorescent protein (FP protein) under the control of a promoter operative in the endosperm, comprising the step of exposing the endosperm of the seed to a wavelength exciting the FP protein, and measuring the intensity of the emitted fluorescence.
    Type: Grant
