Abstract
The present invention is directed to a vector for transferring heterologous DNA into a plant cell. The vector is based on the bacterial artificial chromosome (BAC) vector designed for the construction of genomic libraries with large DNA inserts, and the binary (BIN) vector designed for Agrobacterium-mediated plant transformation. The BIBAC vector according to the subject invention allows the construction of plant genomic libraries with large DNA inserts that can be directly introduced into plants by transformation mediated by Agrobacterium.
Claims27
A vector for transferring heterologous DNA into a plant cell, said vector comprising:
- a backbone which includes a first origin of replication for maintaining heterologous DNA as a single copy in an Escherichia coli host cell, and which further includes a second origin of replication for maintaining heterologous DNA as a single copy in an Agrobacterium tumefaciens host cell;
- a unique restriction endonuclease cleavage site for insertion of heterologous DNA;
- and
- left and right Agrobacterium T-DNA border sequences flanking said unique restriction endonuclease cleavage site, said left and right T-DNA border sequences allowing introduction of heterologous DNA located between said left and right T-DNA border sequences into a plant cell.
