Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 14 words
A plant having plastids in which the genomes of said plastids contain heterologous DNA.
Claim 2
Dependent Claim 14 words
A plant having plastids in which the genomes of said plastids contain heterologous DNA.
Claim 3
Dependent Claim 16 words
The plant of claim l, wherein said heterologous DNA includes DNA encoding a selectable marker protein.
Claim 4
Dependent Claim 23 words
The plant of claim l, wherein said heterologous DNA includes a site for the insertion of a gene encoding a desired heterologous protein.
Claim 5
Dependent Claim 19 words
The plant of claim 3, wherein there is inserted, in said site, said gene encoding said desired heterologous protein.
Claim 6
Dependent Claim 10 words
The plant of claim l, wherein said plastids comprise chloroplasts.
Claim 7
Dependent Claim 80 words
A vector capable of effecting the integration of a portion of itself into the genome of a plastid, said vector containing a transposon including a gene encoding a selectable marker protein and having insertion sequences on either side of said gene encoding said selectable marker portion, said vector further comprising, on either side of said insertion sequences, a first and second DNA region which together comprise a DNA region homologous with a DNA region of said genome of said plastid.
Claim 8
Dependent Claim 80 words
A vector capable of effecting the integration of a portion of itself into the genome of a plastid, said vector containing a transposon including a gene encoding a selectable marker protein and having insertion sequences on either side of said gene encoding said selectable marker portion, said vector further comprising, on either side of said insertion sequences, a first and second DNA region which together comprise a DNA region homologous with a DNA region of said genome of said plastid.
Claim 9
Dependent Claim 22 words
The vector of claim 6, wherein said transposon includes a site for the insertion of a gene encoding a desired heterologous protein.
Claim 10
Dependent Claim 19 words
The vector of claim 7, wherein there is inserted, at said site, said gene encoding said desired heterologous protein.
Claim 11
Dependent Claim 11 words
The vector of claim 8, wherein said plastid is a chloroplast.
Claim 12
Dependent Claim 27 words
l0. The vector of claim 9, wherein said desired heterologous protein participates in a chemical reaction which occurs more efficiently inside said chloroplast than outside said chloroplast.
Claim 13
Dependent Claim 20 words
A plastid in which the genome thereof has integrated into it said integrating portion of the vector of claim 6.
Claim 14
Dependent Claim 11 words
The plastid of claim ll, wherein said plastid is a chloroplast.
Claim 15
Dependent Claim 9 words
A plant cell containing the plastid of claim ll.
Claim 16
Dependent Claim 11 words
A plant comprising a plurality of the cell of claim l3.
Claim 17
Dependent Claim 46 words
A method of producing a plant whose cells express a desired gene, comprising a) isolating plastids from a plant, b) transforming said plastids with the vector of claim 6, c) inserting said transformed plastids into plant cells, and d) regenerating a plant from said plant cells.
Claim 18
Independent Claim 10 words
The method of claim l5, wherein said plastids comprise chloroplasts.
Claim 19
Dependent Claim 8 words
A plastid which is transformed with heterologous DNA.
Claim 20
Dependent Claim 8 words
A plastid which is transformed with heterologous DNA.
Claim 21
Dependent Claim 11 words
The plastid of claim l7, wherein said plastid is a chloroplast.
