  • Patent number: 5530191
    Abstract: The present invention provides a cytoplasmic male sterility (CMS) system for plants, which is based on modification of the plastid genome. The CMS system comprises three transgenes: a "plastid male sterility" (pms) gene, regulated by a "nuclear male sterility" (rims) gene and a "restorer of male fertility" (rmf) gene. The pms gene is either an inactive gene encoding a toxic gene product or an actively expressed gene encoding an essential gene product. The runs gene is controlled by an anther-specific promoter, and encodes a plastid-directed polypeptide that regulates the pms gene, either by activating expression of the inactive toxic pms gene or by repressing expression of the essential pms gene, which causes plastid and cellular disablement or death in anther tissue, thereby preventing formation of viable pollen. The rmf gene encodes a gene product that prevents the rims gene from regulating the pms gene.

  • Patent number: 5478369
    Abstract: Nucleotide sequences mediating male fertility in plants are described, with DNA molecule and amino acid sequences set forth. Use of the nucleotide sequences to mediate fertility in plants is also described. In one such method, an inducible promoter is used to regulate expression of the DNA molecule. The control sequences are modified so that it is normally "off" and as a result the plants are male sterile. When it is desired to reproduce the male sterile plants, male fertility is restored by treating the plants with a non-phytotoxic chemical which induces expression of the critical gene.

  • Patent number: 5457274
    Abstract: A pink-flowered soybean plant which possesses large seeds and high protein seed content, without a concomitant decrease in yield. The pink-flowered soybean plant is easily distinguished from wild-type and domesticated cultivars by virtue of its unique flower color and appearance. The two commercially significant traits, large seed size and high protein seed content, cosegregate with the pink flower trait. Seed size and protein content of soybean cultivars are therefore efficiently and quickly increased by crossing with the pink-flowered plant, then selecting for pink-flowered progeny. Prior difficulties in tracking and monitoring increases in seed protein content are eliminated.

  • Patent number: 5409823
    Abstract: The present invention provides a dual method for producing male-sterile plants. Two genetically transformed plants, parents 1 and 2 are crossed to obtain male-sterile offspring. Parent 1 is transformed with an expression cassette comprising a nucleotide sequence encoding an anther-specific promoter which is operably linked to a nucleotide sequence encoding a transactivator. Parent 2 is transformed with an expression cassette comprising a target nucleotide sequence, which is capable of being activated by the transactivator, operably linked to a nucleotide sequence which encodes RNA or a polypeptide which will disrupt the formation of viable pollen. Therefore, crossing parent 1 with parent 2 results in male-sterile offspring. The male-sterile plants are useful for producing hybrid seed.The invention also provides compositions and methods for high level expression of a coding region of interest in a plant.

  • Patent number: 5356799
    Abstract: A process is described for producing hybrid seed using male-sterile plants created by employing molecular techniques to manipulate antisense DNA and other genes that are capable of controlling the production of fertile pollen in plants. Transformation techniques are used to introduce constructs containing antisense DNA and other genes into plants. Said plants are functionally male-sterile and are useful for the production of hybrid seed by the crossing of said male-sterile plants with pollen from male-fertile plants. Hybrid seed production is simplified and improved by this invention and can be extended to plant crop species for which commercially acceptable hybrid seed production methods are not currently available.

  • Patent number: 5331108
    Abstract: A maize plant has in its genome a non-mutable form of a mutant allele designated vitX-8132. The allele is located at a locus designated as glt which conditions kernels having an altered starch characteristic. Maize plants including such a mutant allele produce a starch that does not increase in viscosity on cooling, after heating.

  • Patent number: H1498
    Abstract: A set of nucleic acid probes useful for tracking Maize Dwarf Mosaic Virus Resistance (MDMV), a polygenic trait, is provided. Chromosome segments are identified enabling isolation of the genes governing this trait.A general method for identifying probes useful for tracking and introgressing polygenic traits into elite genomes and identifying chromosome segments governing the traits is also provided. This method involves the analysis of RFLP polymorphisms between parent donor and recipient genotypes and observed phenotypic data using multiple regression by leaps and bounds ("leaps"), followed by standard multiple regression applied to the "leaps" data. The "leaps" data may be used to identify flanking markers, and epistasis may be determined by analysis of the multiple regression data.Kits comprising a subset of the most useful probes (those most closely linked to the trait of interest) are provided. The kits may also comprise flanking probes.
