Patent ID: 7718848

Claim:
A process of producing a protein of interest in an F1 seed, said process comprising: (a) hybridizing a first and a second transgenic parental plant, whereby an F1 seed is produced, wherein said first transgenic parental plant has integrated in its genome a precursor of a replicating DNA as a first partial genetic endowment, said replicating DNA encoding said protein of interest and comprising a plant geminiviral origin of replication and a nucleic acid sequence encoding a plant geminiviral replicase, said second transgenic parental plant encodes, as a second partial genetic endowment, a site-specific recombinase, integrase or flippase for generating said replicating DNA by rearranging the precursor of said replicating DNA by site-specific recombination, and said hybridizating generates in said F1 seed said replicating DNA by combining in said F1 seed said first and said second partial genetic endowments of said first and said second transgenic parental plant; and (b) isolating from said F1 seed or a seedling thereof, (i) said protein of interest, or (ii) if said protein of interest is an enzyme, a chemical compound the synthesis of which said enzyme is involved in.
