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
