  • Patent number: 8273871
    Abstract: Provided is an improved design of shRNA based on structural mimics of miR-451 precursors. These miR-451 shRNA mimics are channeled through a novel small RNA biogenesis pathway, require AGO2 catalysis and are processed by Drosha but are independent of DICER processing. This miRNA pathway feeds active elements only into Ago2 because of its unique catalytic activity. These data demonstrate that this newly identified small RNA biogenesis pathway can be exploited in vivo to produce active molecules.

  • Patent number: PP23068
    Abstract: ‘Merbeingold 2336’ is a new Australian variety of mandarin. It was selected from the progeny obtained following a controlled pollination of ‘Imperial’ mandarinבEllendale’ tangor in 1984. It was selected because it is pollen sterile, strongly parthenocarpic and yields seedless fruits, which are sweet, juicy and easy-to-peel. Fruit maturity is early-to-mid season in the Murray Valley of Australia. Internally, the flesh of ‘Merbeingold 2336’ is attractive, orange in colour and tender with soft segment walls.
