          USA. The networks of collaboration among authors, research institutes and countries, the co-occurrence of
        
        
          keywords and co-citations of the retrieved literature are all analyzed. It uses visualization map to explore the
        
        
          research frontiers and hot spots in the field of genomics at home and abroad, and also contracts and analyzes the
        
        
          domestic and foreign research status of genomics.
