摘要： An efficient selection and plant regeneration protocol for Agrobacterium-mediated transformation, using cotyledon node zone-stem connection region of melon, has been developed. The new Agrobacterium-mediated transformation methodology, independent of organ culture, used the entire germinated seed as explants. The transformation system was maximized to maintain the integrity of melon itself, thus avoiding the limitations of traditional tissue culture methods. The transformation was carried out under a non-sterile environment. The incorporation of a selectable marker (neomycin phosphotransferase II) into the genome of transgenic plants was confirmed by PCR and Southern blot analyses. The transformation frequency based on the PCR was 13%. Transgenic melon plants were usually detected by PCR in less than 1 month after Agrobacterium inoculation, and seeds could be harvested in 3 months. The growth characteristics and morphology of the transgenic plants were identical to the untransformed wild-type plants. This method would be beneficial for facilitating the characteristics of gene functions and for boosting the manipulation of melon transformation for commercial purposes.
