Dr. Qijun Chen obtained the doctoral degree at the China Agricultural University in 2002. Since September 2004, he has been working in the College of Biological Sciences, China Agricultural University. Dr. Chen's current research focuses on the plant gene editing with the ternary vector system. Recently, his lab developed a novel ternary vector system to integrate the MR（Morphogenic Regulator） and CRISPR/Cas modules. This ternary vector system is composed of new pGreen-like binary vectors including pGreen3 and a pVS1-based virulence helper plasmid, which also functions as a replication helper for the pGreen3 vectors in Agrobacterium tumefaciens
