摘要:
A population of seeds wherein substantially all of the seeds in the population have a portion of seed tissue removed by an automated sampling system. Substantially all of the seeds in the population have the presence or absence of at least one transgene in common, and/or substantially all of the seeds in the population have a high recurrent parent allele frequency. The presence or absence of the at least one transgene in the seeds in the population and/or the recurrent parent allele frequency in the seeds in the population is determined by analyzing the portion of seed tissue removed from the seeds by the automated sampling system.
摘要:
An automated seed sampler includes a sampling station; a sampler for removing material from a seed in the sampling station; a seed conveyer for conveying the seed from the sampling station to a compartment in a seed tray; and a conveyor for conveying the material removed from the seed to a corresponding compartment in a sample tray. The method of the present invention comprises feeding seeds individually to a sampling station, removing a sample from the seed in the sampling station; conveying the sample to a compartment in a sample tray, and conveying the seed to a corresponding compartment in a seed tray. The samples can be tested, and the seeds can be sorted according to the results of the testing of their corresponding samples.
摘要:
The present invention concerns double stranded RNA compositions and transgenic plants capable of inhibiting expression of genes essential to establishing or maintaining nematode infestation in a plant, and methods associated therewith. Specifically, the invention relates to the use of RNA interference to inhibit expression of a target OPR3-like plant gene, and relates to the generation of plants that have increased resistance to parasitic nematodes.
摘要:
Materials and methods for modulating expression of nucleic acid sequences of interest, e.g., nucleic acid sequences involved in alkaloid biosynthesis, are disclosed. For example, plants and plant cells containing a regulatory protein that can modulate expression of a gene(s), such as an alkaloid biosynthesis gene(s), are disclosed.
摘要:
A hydro-seeding composition having the form of an aqueous mixture comprising a polyacrylamide polymer and seeds. The polyacrylamide polymer is a potassium anionic polymer salt or an ammonium anionic polymer salt, instead of a sodium-based polyacrylamide polymer. The hydro-seeding composition may also include various soil amendments. The seeds are grass seeds or plant seeds.
摘要:
The present invention provides alfalfa varieties which contain enhanced pectin content and methods of use of same. These varieties may be used to produce inbreds or hybrids or to produce food or feed products. Parts of these plants, including plant cells, are also provided.
摘要:
The present invention provides for the identification and cloning of functional plant centromeres in Arabidopsis. This will permit construction of stably inherited minichromosomes which can serve as vectors for the construction of transgenic plant and animal cells. In addition, information on the structure and function of these regions will prove valuable in isolating additional centromeric and centromere related genetic elements and polypeptides from other species.
摘要:
This invention relates to an isolated nucleic acid fragment encoding a biotin synthases. The invention also relates to the construction of a chimeric gene encoding all or a portion of the biotin synthases, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the biotin synthases in a transformed host cell.
摘要:
An absorbent product containing sphagnum moss selected from the group of botanical sections consisting of PALUSTRIA, ACUTIFOLIA, RIGIDA, SUBSECUNDA and CUSPIDATA. The invention also extends to a novel method for manufacturing a highly absorbent structure and to a method for evaluating the liquid absorbent properties of a sphagnum moss composition.
摘要:
Plant tissues of mosses such as cut tissue pieces, gametophores, calluses, protonemata, spores, gemmae, subterranean stems or rhizoids are purely cultured in a culture medium to generate seedlings (cultigen) corresponding to plumules, and the seedlings are sown onto a nursery at a desired colony density, followed by appropriate caring.
