Fibrillarin known as a RNA methyl transferase that has recently been shown to also methylate Histone H2A. Besides the escential role in the cell, Fibrillarin is also highjack by several virus and it is required for their progression through the floem. Becourse of their relevance and its good level of protein conservation in almost all eukaryotic cells and all archea kingdom we check its evolution. Some plants have had several duplications of their genome and therefore several copies of this protein are present, however our results show the unexpected that their sinteny is maintain showing some interesting genes that have been kept during the different steps in evolution. Here we show its evolution through eukaryotic genomes as well as the changes in sequences that interact with virus.
Take Away Notes:
• Fibrillarin is a essential gene required for methylation and rRNA processing that is required for all protein translation. Changes in this protein have a dramatic impact on cell viability and protein level.
• Here the chromosomal sequences that surround fibrillarin have been analyzed in more than 300 genomes as well as changes that are required for viral progression in plant cells.
