Cellulose is a major component of plant cell which found in both primary and secondary cell wall and synthesized by cellulose synthase (CESA) complexes. The partial sequences of OsCESA4 and OsCESA9 genes in seven varieties of native upland rice were determined.. The results found that OsCESA4 sequences showed the similarities to Oryza sativa Japonica (98.7-99.5%) and Oryza sativa Indica (97.5-99.5%). While all seven OsCESA9 sequences revealed the same identity to both Oryza sativa Japonica (98.46%) and Oryza sativa Indica (98.46%). Since, lodging problems in the native upland rice which has been cultivated in Prachuap Khiri Khan Province (Pala U village) still unsolved. Therefore, the analysis of cellulose synthase genes of these varieties would be used to fulfill the genetic information for further upland rice breeding improvement.
