摘要:
The field of the invention is inducible gene expression systems wherein expression is controlled by a novel ecdysone or ultraspiracle receptor or its derivatives. The field particularly relates to the isolation and characterization of nucleic acid and polypeptides for a novel ecdysone receptor and a novel ultraspiracle receptor. The nucleic acid and polypeptides are useful in novel gene expression systems inducible with ecdysone or derivative receptor agonists.

The present invention relates to an isolated nucleic acid sequence encoding the Ms45 male tissue-preferred regulatory region. In one aspect this invention relates the use of this male tissue-preferred regulatory region in mediating fertility. An example of such use is the production of hybrid seed such as in a male sterility system. The Ms45 male tissue-preferred regulatory region can be operably linked with exogenous genes, such as those encoding cytotoxins, complementary nucleotidic units and inhibitory molecules. This invention also relates to plant cells, plant tissue and differentiated plants which contain the regulatory region in this invention.

The present invention relates to isolated male tissue-preferred regulatory sequences from Ms45 gene. The invention also relates to the use of Ms45 gene male tissue-preferred regulatory sequences in mediating male fertility in a plant, and in producing hybrid seed. The Ms45 male tissue-preferred regulatory region can be operably linked to exogenous genes encoding cytotoxins or inhibitory molecules. The invention also relates to plant cells, plant tissue and plants that contain the MS45 gene regulatory sequences.
摘要:
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.

The invention provides transgenic maize event MON 87427 and plants, plant cells, seeds, plant parts, and commodity products derived from event MON 87427. The invention also provides nucleotides specific for transgenic maize event MON 87427 and plants, plant cells, seeds, plant parts, and commodity products comprising nucleotides specific for transgenic maize event MON 87427. The invention also provides methods related to transgenic maize event MON 87427 and to the Roundup® Hybridization System (RHS). The invention also provides a Relative Development Scale useful for monitoring and determining reproductive development in maize that reconciles developmental differences across various maize varieties. This is useful for determining the optimal timing of a treatment regimen in which tassel development stage is an important factor, including various methods in making hybrid seed.
