摘要: Nucleotide sequences, amino acid sequences, and an associated promoter sequence are useful in methods of controlling male fertility in plants. Recombinant expression cassettes, vectors, plant cells, and plants comprise a disclosed nucleotide sequence and may encode a disclosed amino acid sequence. The recombinant expression cassettes are useful in controlling fertility, especially male fertility of annual crops. The promoter is useful in driving expression of an operably-linked heterologous polynucleotide. Constructs comprising homology to the promoter sequence are useful for downregulation of a polynucleotide associated with the promoter.

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.

摘要: Pairs of 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. Also provided are methods for maintaining a homozygous recessive condition and for repressing transmission of transgenes.

摘要: Compositions and methods are provided for genome modification of a nucleotide sequence located in or near a male fertility gene of MS9, MS22, MS26, or MS45 in the genome of a plant cell or plant to produce a male-sterile plant. In some examples, the methods and compositions employ a guide RNA/Cas endonuclease system for modifying or altering target sites located in or near a male fertility gene of MS9, MS22, MS26, or MS45 in the genome of a plant cell, plant or seed to produce a male-sterile plant. Also provided are compositions and methods employing a guide polynucleotide/Cas endonuclease system for genome modification a nucleotide sequence located in or near a male fertility gene of MS9, MS22, MS26, or MS45 in the genome of a plant cell to produce a male-sterile plant. Compositions and methods are also provided for restoring fertility to a Ms9, Ms22, Ms26, or Ms45 nucleotide sequence to a male-sterile Ms9, Ms22, Ms26, or Ms45 plant produced using the methods and compositions described herein.

摘要: Provided herein are methods and compositions for restoring fertility and maintaining sterility in plants. In particular, one method disclosed includes introducing into a male-sterile plant, wherein the plant comprises one or more homozygous mutations in a male-fertility gene, a plant restoration donor chromosomal component comprising a plant-derived polynucleotide that confers a plant phenotypic marker linked to a male-fertility restoration locus that functionally complements the male-sterility phenotype from the one or more homozygous mutations in the male-sterile plant. In some examples, the plant-derived polynucleotide that confers a plant phenotypic marker and the male-fertility restoration locus are linked to each other and located on the same chromosomal arm on the plant restoration donor chromosomal component. In some examples, the plant-derived polynucleotide that confers a plant phenotypic marker, the male-fertility restoration locus, or both are modified.
