摘要：
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.
