Abstract: A transformation method, including the following steps: preparing an Agrobacterium Ti-plasmid, Escherichia coli plasmid, or other DNA vectors carrying exogenous genetic fragments as a genetic donor; collecting a male gamete (pollen) of the plant as a recipient; preparing a 5-50% sucrose solution after aeration and low temperature pretreatment; mixing the pollen with the exogenous genetic fragments in the 5-50% sucrose solution; transferring the exogenous genetic fragments into the pollen in the presence of ultrasonication; pollinating a pistil stigma of the plant with the treated pollen; harvesting seeds at maturity; sowing the seeds in a subsequent growing season; screening a germinating seed and a seedling; and performing PCR amplification and Southern hybridization using DNA samples of plants to further determine transformants.
