Patent number: 10155961Abstract: 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: GrantFiled: March 12, 2013Date of Patent: December 18, 2018Assignees: PIONEER HI-BRED INTERNATIONAL.

Patent number: 9631203Abstract: Genetic male sterile plants are provided in which complementing constructs result in suppression of a parental phenotype in the progeny. Methods to generate and maintain such plants and methods of use of said plants, are provided, including use of parental plants to produce sterile plants for hybrid seed production.Type: GrantFiled: March 12, 2013Date of Patent: April 25, 2017Assignees: PIONEER HI-BRED INTERNATIONAL, INC., E I DU PONT DE NEMOURS AND COMPANYInventors: Marc Albertsen, April Leonard, Bailin Li, Bo Shen

Patent number: 7893317Abstract: Nucleotide sequences mediating male fertility in plants are described, with DNA molecule and amino acid sequences set forth. Promoter sequences and their essential regions are also identified. The nucleotide sequences are useful in mediating male fertility in plants. In one such method, the homozygous recessive condition of male sterility causing alleles is maintained after crossing with a second plant, where the second plant contains a restoring transgene construct having a nucleotide sequence which reverses the homozygous condition. The restoring sequence is linked with a hemizygous sequence encoding a product inhibiting formation or function of male gametes. The maintainer plant produces only viable male gametes which do not contain the restoring transgene construct. Increase of the maintainer plant is also provided by self-fertilization, and selection for seed or plants which contain the construct.Type: GrantFiled: May 24, 2010Date of Patent: February 22, 2011Assignee: Pioneer Hi-Bred International, IncInventors: Marc Albertsen, Tim Fox, Gary Huffman, Mary Trimnell, Yongzhong Wu, Howard Hershey
