  • Regulation of fungal fruiting body development
    Patent number: 11668702
    Abstract: The present invention provides for a fungus, especially in the form of fungal mycelium, that has altered glycogen synthase kinase-3 (GSK-3) expression and/or activity level and therefore exhibits modified characteristics in fruiting body development. Also provided are compositions and methods for generating living fungal mycelium with altered fruiting body development.
    Type: Grant
    Filed: September 20, 2018
    Date of Patent: June 6, 2023
    Assignee: The Chinese University of Hong Kong
    Inventors: Jinhui Chang, Hoi Shan Kwan, Man Chun Wong, Po Lam Chan, Yichun Xie, Wing Chee Beatrice Ho

  • Authentication of biologic materials using DNA-DNA hybridization on a solid support
    Patent number: 7816502
    Abstract: Provided are a method for preparing an array for authenticating biological samples and a method for authenticating the biological samples based on analysis of variable sequences of ribosomal RNA genes as well as a kit for authentication of the biological samples. The hybridization of probes of the samples to the array of overlapping fragments of authentic variable ribosomal RNA gene regions is quantified. The test enables distinction of species or prokaryotic strains and is unaffected by intra-species or strain polymorphism. The method disclosed is illustrated by authentication of traditional Chinese medicinal materials.
