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
* ''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''

== 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)
* '''CS1''' family
** '''CslB/H/E/G/J''' families have evolved more rapidly than the other Csl families, which lends further support for the hypothesis that these families might have diversified relatively recently to acquire new functions specific to the seed plants
* '''CslE''':
** diverged separately after the split of dicots and monocots.
** CslE, this family is also substantially expanded in the grape genome possibly as a result of tandem gene duplications
* '''CslG and CslJ''':
**CslG family diversified separately in each dicot plant via intragenomic duplications
** CslJ is possibly a new family and gene sequences are highly conserved
* '''CslB and CslH''':
** CslB is a dicot-specific family while CslH is monocot-specific
** paralogous genes of these two families tend to form clusters and have similar gene structures (except for Os04g35020.1) (Figure 5), suggesting the possibility of independent genome-specific duplications followed by subsequent sequence divergence.
