Abstract
The present invention is generally related to plant genetic engineering. In particular, the invention provides methods of inhibiting programmed cell death in maize and other grasses. This invention also provides transgenic maize plants having kernels with multiple embryos and kernels from transgenic maize plants having multiple embryos.
Claims27
A method of inhibiting programmed cell death in a maize plant comprising introducing a construct comprising a programmed cell death inducible promoter operably linked to a nucleotide sequence that inhibits programmed cell death into said plant, whereby programmed cell death in the lower floret of said plant is inhibited.
A transgenic maize plant comprising an expression cassette comprising a programmed cell death-inducible promoter operably linked to a nucleotide sequence encoding an inhibitor of programmed cell death, the maize plant having kernels with multiple embryos.
A kernel from a transgenic maize plant comprising multiple embryos, wherein the kernel has increased oil and protein content.
A method of inhibiting programmed cell death in a maize plant comprising introducing a promoter from a floret specific gene operably linked to a nucleotide sequence that inhibits programmed cell death into said plant, whereby programmed cell death in the lower floret of said plant is inhibited.
