  • Patent number: 6603062
    Abstract: Provided is a method for producing transgenic monocotyledonous plants, plant cells, plant parts, seeds, and reproduction material with modified 5-aminolevulinic acid biosynthesis. This is achieved by stably integrating one or several nucleic acid molecules coding for a protein with a 5-aminolevulinic acid synthase function (ALAS) isolated from the alpha group of purple bacteria, an active fragment thereof or an antisense or complementary sequence thereof, into tie plant genome in stable form. This method can also be used to control undesired vegetation Also provided is a method for producing transgenic plants or plant cells whose glutamate-1-semialdehyde transferase (GSAAT) expression is suppressed or inhibited by stable integration of at least one nucleic acid molecule encoding an ALAS isolated from the alpha group of purple bacteria into the plant plastome by plastid transformation.

  • Patent number: 6563026
    Abstract: This invention relates to transgenic winter oilseed rape (WOSR) plants, plant material and seeds, wherein harboring a specific transformation event. It pertains to winter oilseed rape plants, more particularly to a pair of winter oilseed rape plants, which is particularly suited for the production of hybrid seed. More specifically, one plant is wherein being male-sterile, due to the presence in its genome of a male sterility gene, while the other is wherein carrying a fertility-restorer gene, capable of preventing the activity of the male-sterility gene. The invention further provides a method for producing hybrid seed, a process for producing a transgenic WOSR plant oil or plant, and a method to identify a transgenic plant, cell or tissue. A kit for identifying the transgenic plants comparing the elite event of the present invention is also described.

  • Patent number: 6541273
    Abstract: Methods and apparatus are disclosed which are useful for detecting the presence of various pesticides, including aryl pyrazoles such as fipronil. Pesticide residues are extracted from a variety of samples, including soil and/or water samples using techniques well known to those of skill in the art. The samples are then concentrated, and transferred to an solid phase extraction cartridge. The SPE cartridge includes activated charcoal, silica gel, magnesium-silica gel and an amino-functional silica sorbent, or suitable equivalents thereof. After cleanup, the eluate containing the analyte of interest can be concentrated to a standard sample size and the amount of pesticide residues quantitated. In a preferred embodiment, the column chromatography materials are assembled in a solid phase extraction cartridge with frits between the chromatography materials. This facilitates the use of the cartridge in standard automated analytical equipment, for example, robotic equipment.
