          1.1 Publication amount analysis
        
        
          According to the retrieving results in the Web of Science and CNKI, we analyzed the number of published
        
        
          genomics related articles (from 1985 to 2016) and made a list of them (Table 1).

          The number of published genomics related articles is increasing year by year (Figure 1). It reaches almost as high
        
        
          as 4000 pieces in 2015, which indicates that more and more researchers and researching institutes abroad have
        
        
          attached great importance to genomic studies and have obtained abundant research achievement. Compared with
        
        
          that, the number of published articles in China shows an upward trend in fluctuation since 1997. Moreover, there
        
        
          is sudden increase from 2013 to 2015, which illustrates that our country has increased the investment in genomics
        
        
          related fields in recent years, and has made great progress.
