Ancestral Eurosid

  1. Data generated by Chungfang Zheng and David Sankoff
  2. Procedure for generating ancestral genome:
    1. Take ancestral ortholog sets from grape/chocolate/peach
    2. Use the ortholog gene from first grape, then chocolate, then peach (if data is missing)
    3. Extract CDS sequence from CoGe
    4. Reverse complement if necessary
    5. Print sequence
    6. Pad with 1000 "N"s between coding sequence
