  • Publication number: 20250092425
    Abstract: The present disclosure belongs to the technical field of gene editing, and specifically provides a FgTad2-FgTad3-Amel editing enzyme system, an editing tool, and an editing method. In the present disclosure, the system is a ternary complex composed of three genes (proteins), FgTAD2, FgTAD3, and AME1, and can catalyze A-to-I editing on mRNAs. Extensive A-to-I mRNA editing can be detected by expressing the AME1 gene in vegetative stage of Fusarium graminearum. Transforming the FgTad2-FgTad3-Ame1 editing enzyme system into Saccharomyces cerevisiae, Escherichia coli, and human cells to allow expression can produce A-to-I mRNA editing. This indicates that a Fusarium graminearum-derived A-to-I mRNA editing system is active and broadly adaptable, and has a great potential to be developed as a gene editing tool in different organisms.

  • Patent number: 8409791
    Abstract: Disclosed is a double-sided color photographic paper, including, in order, a first protection layer, a first photosensitive layer, a supporting substrate, a second photosensitive layer and a second protection layer. The supporting substrate has a first surface and a second surface opposite to the first surface. A first barrier layer and at least one layer of a first shading layer are sandwiched between the first photosensitive layer and the first surface of the supporting substrate. The first barrier layer is arranged between the first photosensitive layer and the first shading layer; a second barrier layer and at least one layer of a second shading layer are sandwiched between the second surface of the supporting substrate and the second photosensitive layer, and the second barrier layer is arranged between the second shading layer and the second photosensitive layer.
