    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: 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.
