  • 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.

  • Patent number: 8334429
    Abstract: Auxotrophic Agrobacterium and methods employing auxotrophic Agrobacterium are provided. Auxotrophic Agrobacterium may be used in a variety of methods including biologically containing Agrobacterium comprising a transgene and transforming a plant cell without using an Agrobacterium counter-selective agent. Transforming maize immature embryos using an Agrobacterium auxotrophic for thymidine results in comparable transformation efficiency as transformation achieved using prototrophic Agrobacterium. Methods for producing an Agrobacterium thymidine auxotroph and using the auxotroph in transformation methods are disclosed. Transformed tissues and plants produced using methods of the present invention are also provided.
