  • Patent number: 10870860
    Abstract: A nuclear maize gene is mutated to result in dominant male sterility. Two mutants are provided which impact signal peptide processing. Restoration constructs and methods are provided for use of the dominant male-sterile mutants in producing hybrid seed for male-sterile hybrid plants. Other signal-peptide modifications are provided. Orthologs of the wild type or mutated gene in various species are provided.
    Type: Grant
    Filed: November 19, 2018
    Date of Patent: December 22, 2020

  • Publication number: 20130180009
    Abstract: Compositions and methods for regulating expression of heterologous nucleotide sequences in a plant are provided. Compositions include promoter sequences with direct expression in an egg cell or embryonic cell-preferred manner. Such compositions find use in, for example, a method for expressing a heterologous nucleotide sequence in a plant; detection of specific cell types in the ovule and targeted ablation of specific cell types.
