-DNA analysis techniques have received  a lot of attention  these last 
-years,  because they play an  important role  in understanding 
-genomes evolution over time, and in phylogenetic and genetic analyses. Various models 
-of genomes evolution  are based on the analysis  of DNA sequences, SNPs, 
-mutations, and so on. We have recently investigated the use of
-core (\emph{i.e.}, common  genes) and pan genomes  to infer evolutionary information 
-on a collection of 107 chloroplasts. In particular,
-we have regarded methods to  build a genes content evolutionary tree  using  
-distances to core  genome. However,  
-the production of reliable core and pan genomes is not an easy task,
-due to error annotations of the NCBI. The presentation will then
-consist in various compared approaches to construct such a tree using
-fully annotated genomes by NCBI and Dogma, followed by a gene quality 
-control among the  common genes. We will finally explain how, by comparing 
-sequences from Dogma with NCBI contents, we achieved to identify the 
-genes that play a key role in the dynamics of genomes evolution. \\
