摘要：

Efficient delivery of genomic DNA fragments to maize protoplasts was obtained by new methods using the polycation Polybrene or Lipofectin cationic liposomes. Stable kanamycin-resistant secondary transformants were recovered after transfection with genomic DNA from a maize cell line that had previously been tagged with the bacterial gene neomycin phosphotransferase (nptII) in a first-round transformation. The frequency of secondary transformants with nptII-homologous DNA sequences was 3% or 6% of all randomly picked microcalli after Polybrene or Lipofectin-mediated transfection, respectively. Transformation with genomic DNA by these methods may allow easy transfer of uncloned genes encoding desirable characteristics to crop species that can be regenerated from protoplasts. © 1990 Springer-Verlag.
