Progress on Application of Plastid Genetic Engineering in Plant Breeding
Compared with traditional nuclear transformation system,plastid genetic engineering that performs much safer,more precise and efficient expression of foreign genes has made great achievements in crop quality and yield improvement,even offers new ideas for plant breeding.This paper reviewed the plastid transformation techniques,screening markers(systems) and their applications in the improvement of plant resistance traits,yield and quality and heterosis utilization,so as to provide theoretical reference for the application of plastid genetic engineering in plant breeding,especially in monocotyledonous plants.
