pBINPLUS: An improved plant transformation vector based on pBIN19

Abstract
We describe the construction of a new plant transformation vector, pBINPLUS, based on the popular pBIN19 vector. Improvements over pBIN19 include location of the selectable marker gene at the left T-DNA border, a higher copy number inE. coli, and two rare restriction sites around the multiple cloning site for easier cloning and analysis of T-DNA insertions in plant genomes.
