The Cellulose Synthase super family in fully sequenced plants and algae BMC plant biology 2009, 9:99

  • OBJ: Systematic investigation of 9 Cs1 and 1 CesA gene family from 17 seqeunced algal genome
  • Take Home Points:
    • CesA is a super family consists of many Cs1 family of which Cs1A, CslF, CslC, CslH, CslC are some of them
    • The backbone synthases of all major hemicellulose classes except for xylans are known.
    • CSL hypothesis ?
    • CslA and CslC families originated through an ancient gene duplication event in land plants
  • Results
    • CS1 Family classification
      • Carried out through protein domain similarity
      • A new Csl family was discovered very recently in cereals and named CslJ (specific to cerials)
      • Ka/Ks of CS1 family
        • Generally, a lower selection pressure indicates a higher evolutionary rate
        • Genes that originated relatively recently through gene duplications or by other mechanisms usually evolve more rapidly than the more ancient genes
