A simple Gateway-assisted construction system of TALEN genes for plant genome editing.

ABSTRACT: TALEN is an artificial nuclease being applied for sequence-specific genome editing. For the plant genome editing, a pair of TALEN genes is expressed in the cells, and a binary plasmid for Agrobacterium-mediated transformation should be assembled. We developed a novel procedure using the Gateway-assisted plasmids, named Emerald-Gateway TALEN system. We constructed entry vectors, pPlat plasmids, for construction of a desired TALEN gene using Platinum Gate TALEN kit. We also created destination plasmid, pDual35SGw1301, which allowed two TALEN genes to both DNA strands to recruit using Gateway technology. Resultant TALEN genes were evaluated by the single-strand annealing (SSA) assay in E. coli cells. By this assay, the TALENs recognized the corresponding targets in the divided luciferase gene
