Abstract: Abstract: With accomplishment of important model plants－Arabidopsis thaliana and rice (Oryza sativa), investigation of the function of hypothetical genes is one of the most important target in post-genome era. Gene targeting technology, which was universally applied in mammals, was far from the routine technology in plants. Otherwise, most important progresses of gene targeting in plants were made recently. The primary proposal and update of progresses of gene targeting in plants, as well as factors which affect efficiency of gene targeting, were reviewed in this paper.
