| 摘要 |
The invention provides plant transformation vectors, methods for transforming plants and transformed plants. The vectors are designed to avoid incorporation of non-plant DNA into the plant genome. One embodiment of the invention includes use of plant sequences selected from sequences functioning as T-DNA border sequences, selectable markers, recombinase recognition sequences and origins of replication. Another embodiment includes use of additional plant sequences contiguous to border sequences. A further embodiment includes use of vectors having border sequences where the border DNA to be transferred forms part of a plant sequence. |
