摘要

When generating transgenic plants, one of the objectives is to achieve stable expression of the transgene. Trans gene silencing can be avoided by single copy integration of the transgene. Binary systems that predominantly result in single copy integrations, such as BIBAC vectors, are also single-copy in E. coli, the organism in which the T-DNA to be delivered to the plant is assembled. Although a low-copy number is important for stable maintenance of large DNA fragments in E. coli, it hampers cloning into the vector due to a low DNA yield. Here we describe BIBAC vectors to which Gateway site-specific recombination sites are added. These sites provide a fast and easy introduction of sequences of interest into any vector. Our Gateway-compatible BIBAC vectors are available with two selectable markers for plants - resistance to Basta (BIBAC-BAR-GW) and DsRed fluorescence in the seed coat (BIBAC-RFP-GW).
