  • Publication number: 20180258445
    Abstract: 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.

  • Publication number: 20180030471
    Abstract: The present invention provides a seed blend comprising pesticidal seed and refuge seed, wherein plants grown from the pesticidal seed type do not pollinate or have reduced pollination of plants grown from the refuge seed type when the seed blend is planted. Methods for deploying the seed blend and for reducing cross-pollination between plants grown from the pesticidal seed and refuge seed are also provided.

  • Publication number: 20150191743
    Abstract: Nucleotide sequences and amino acid sequences may be useful in methods mediating male fertility in plants, particularly maize, rice, or sorghum. Wild-type and mutant forms are useful for various purposes. Vectors, plant cells, and plants comprise the nucleotide sequences or amino acid sequences. A promoter sequence operably linked to a polynucleotide of interest provides expression preferentially in male reproductive tissue.

  • Publication number: 20140215652
    Abstract: 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.
