Provided is a simple and efficient method of plant genome editing that does not involve the incorporation of a gene cassette for the expression system of a site-specific DNA modification protein. The method of the present invention comprises: (i) a step for mixing plant cells or a tissue containing plant cells together with a site-specific DNA modification protein and a needle-shaped inorganic compound in a liquid medium and making a disturbance to perforate the cells with the needle-shaped inorganic compound, thereby introducing the site-specific DNA modification protein into the cells; and (ii) a step for culturing the plant cells or the tissue containing the plant cells, into which the site-specific DNA modification protein has been introduced in step (i), thereby causing a DNA mutation specific to a target site in the genome of the plant cells.

Described herein is a recombinant cell genetically modified to include a gene cassette comprising a promoter and one or more of a sequence for a recombinase followed by a terminator, the recombinase-terminator sequence being flanked by recognition sites specific for the recombinase, and the cassette being activatable by an external stimulus. Also described are a method for determining the number of times the cell has been activated by an external stimulus, and plastic or rubber or a mixture of plastics or rubber including the recombinant cell, as well as a method for determining the number of times a plastic or rubber has been recycled.

The present disclosure relates to a bryophyte cell that is transformed or genetically modified to express aureusidin synthase and chalcone-4'-glycosyltransferase. The aureusidin synthase and chalcone-4'-glycosyltransferase may be expressed as a single biscistronic cassette separated by a P2A peptide or separately through insertion of two unique gene cassettes into said bryophyte cell. The expression may be driven by an exogenous promoter. The transformed bryophyte cell may be exposed to UV radiation to enhance production of exogenous flavonoids.

This invention relates to a method for increasing the yield of polyketide compounds by splitting a modular polyketide synthase gene. (1) Constructing a RedEx gene cassette for splitting the modular polyketide synthase gene; (2) Constructing a target plasmid carrying an amp-ccdB gene selection expression cassette; (3) Constructing a target plasmid carrying an amp-ccdB gene selection expression cassette. C DD-TGA-RBS-ATG- N (3) Target plasmid encoding the DD coding sequence; (4) Construction of recombinant strains; (5) Fermentation culture to obtain polyketide compounds. This invention is the first to discover that the biosynthetic efficiency of host strains carrying the split PKS gene is much higher than that of host strains carrying the natural PKS gene, which can achieve the purpose of increasing the yield of polyketide compounds. Using this method of splitting modular polyketide synthase genes, high-yield butenyl spinosad genetically engineered bacteria and high-yield avermectin genetically engineered bacteria were successfully constructed, which effectively increased the yield of butenyl spinosad and avermectin. The yield of butenyl spinosad increased by a maximum of 30 times, and the yield of avermectin increased by a maximum of 5.8 times.
