  • Patent number: 8932860
    Abstract: The invention provides methods and nucleic acid constructs that may be used to modify a nucleic acid of interest at a target locus within the genome of a host. In some aspects, the invention contemplates producing in vivo a gene targeting substrate (GTS), which may be comprised of both DNA and RNA components. The gene targeting substrate may comprise a gene targeting nucleotide sequence (GTNS), which is homologous to the target locus, but comprises a sequence modification compared to the target locus. The gene targeting substrate may be produced by reverse transcription of a gene targeting message RNA (gtmRNA). The gene targeting message RNA may be folded for self-priming for reverse transcription by a reverse transcriptase. The gene targeting message RNA may in turn be the product of transcription of a gene targeting construct (GTC) encoding the gene targeting message RNA.

  • Publication number: 20140182012
    Abstract: The present invention provides a novel method for the transduction and/or transfection of plant cells. Cell-penetrating peptides (CPPs) have been successfully employed as nanocarriers to deliver proteins and oligonucleotides to single plant cell microspores as well as multi-cellular zygotic embryos. The efficiency of CPP internalization and further delivery of a macromolecular cargo comprising a protein and/or an oligonucleotide can be enhanced by permeabilization of the zygotic embryos.

  • Patent number: 7850745
    Abstract: Methods for recovery of concentrates of lubricating compounds from vegetable and animal oils, fats and greases that allow separation of triglycerides, from components with higher lubricity or enrichment protocols that increase the concentration of high lubricity compounds in the triglyceride. The triglycerides are transesterified with a lower alcohol to produce alkyl esters. Following the conversion process the esters are separated from high molecular weight high lubricity compounds by distillation. The esters have some lubricity and may be sold as pollution reducing fuel components. The high boiling point compounds that are the residues of distillation, however, can contribute significant lubricity and may be used widely in lubricant applications or added to petroleum fuels to decrease friction.

  • Patent number: PP20551
    Abstract: A new and distinct variety of cherry tree named ‘13S2009’ with the following characteristics. ‘13S2009’ has large flattened-heart shaped fruit, with shiny, dark red skin and red to dark red flesh. The fruit has a non-prominent suture and a flat to slightly hollow apex. The fruit matures very late in the harvest season, about 27 days after ‘Van’ and ‘Bing’ and 8 days after ‘Sweetheart’. The flesh of the fruit is very firm, and has a moderately sweet taste. The fruit are tolerant to rain splitting. The stone of ‘13S20-09’ is intermediate in lateral view, large in size, and has strongly developed keel. The tree is upright to spreading, self-compatible, moderately vigorous and has produced good, crops annually since fruiting commenced.

  • Patent number: PP28336
    Abstract: The invention is a new and distinct pear tree variety denominated ‘HW624’. The new pear tree is characterized by producing heavy crops of medium-to large-sized fruit, picked about 2 weeks after ‘Bartlett’. Fruits are green when harvested, turning yellow as fruits ripen, and there is a medium red blush where exposed to the sun. There were no natural fire blight infections on the seedling tree, and results from controlled inoculations indicate a high level of resistance to fire blight. The tree is also highly resistant to pear psylla.
