Abstract:
Phylogenetic trees of cellulose synthase(CesA)gene from 89 sequences of CesA in 15 species including plants and lichen and alga published on the Genebank were generated by MEGA3.1.Based on the information of model plant CesA′s gene regulated the biosynthesis of primary or secondary wall,the function of some unknown genes could be speculated from the trees.The study also found that the CesA genes of Bambusa oldhamii shared the high identity and close phylogenetic relationships with that of maize and barley.The changes of Cys,Ala,Gly and Ser content were greater than that of others in the variable region of CesA′s primary structure.The exchanges between Cys and Ala or Ser or Val in the same site were found in the variable region.
Key words:
Cellulose synthase,
Cane function,
Phylogenetic relationship
