-The study of DNA analysis is playing an important role for studying genome evolution, phylogenetic and genetic analysis in recent years. Various models of genome evolution were made based on the analysis of DNA sequences, SNP, mutation, and so on. This will allows to us to incorporate extinct species into genome evolution trees. In this research, we introduce various methods to build the genome evolution tree based on extracting the core genome (e.g common genes). We built the two evolution trees based on twelve chloroplast genomes from genBank, fully annotated by: NCBI and Dogma. We made then gene quality control among the common genes in NCBI and Dogma. Comparing genes sequences from dogma with their aliases in NCBI will give to us an important role for genome evolution.

+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. \\
