The TALEN targeting technology was applied to rice chloroplast transformation system to improve the integration efficiency of foreign genes in rice chloroplast genome. A TALEN vector for rice chloroplast was constructed according to the homologous recombination sequence of chloroplast expression vector. Molecular analysis and DNA sequencing showed that the vector was successfully constructed. The genes of EGFP,hpt and Fok were expressed in E. coli transformed with the TALEN vector,indicating that the TALEN ...
