摘要：

水稻纤维素合成酶超基因家族由纤维素合成酶基因（cellulose synthase，CesA）和类纤维素合酶基因（cellulose synthase-like protein，Csl）组成，为了解水稻CesA/Csl家族成员序列特征及表达特性，探究其功能，利用生物信息学方法在水稻全基因组中鉴定OsCesA/Csl基因，并对其理化性质、保守基序、基因结构、系统进化、顺式作用元件、染色体定位和共线性等进行分析，利用转录组数据分析OsCesA/Csl的组织表达和不同植物激素处理下的表达。结果表明，在水稻基因组中共鉴定到22个OsCesA/Csl成员，基因编码序列（coding sequence，CDS）长度为774~3 648 bp，蛋白质分子量为28.55~132.16 kD，等电点为6.09~9.62，平均亲水系数为-0.339~0.750，亚细胞定位在细胞膜或高尔基体上。系统进化分为OsCesA和OsCsl，各包含11个成员，分布在除第11号以外的11条染色体上。水稻中存在2组串联重复基因，与玉米更具共线性关系。不同OsCesA/Csl成员的组织表达模式不同，均不同程度地响应茉莉酸、脱落酸、赤霉素和生长素处理。以上研究结果为进一步探索OsCesA/Csl基因家族在水稻生长发育中的功能奠定基础。

Abstract:

Rice cellulose synthase supergene family is composed of CesA （cellulose synthase） and Csl （cellulose synthase-like protein）. In order to understand the sequence characteristics and expression characteristics of the members of the family， and explore their functions， bioinformatics methods were used to identify OsCesA/Csl genes in the whole rice genome. Their physical and chemical properties， conserved motifs， gene structure， systematic evolution， cis-acting elements， chromosome mapping and collinearity were analyzed. Their expression in different tissues and different plant hormone treatments were analyzed based on transcriptome data. The results showed that a total of 22 members of OsCesA/Csl family were identified in rice genome， and the length of gene coding sequence （CDS） was 774~3 648 bp， protein molecular weight was 28.55~132.16 kD， isoelectric point was 6.09~9.62， and average hydrophilic coefficient was -0.339~0.750. The subcellular localization of 22 members was on cell membrane or Golgi apparatus. Phylogenetic evolution divided 22 members into 2 categories： OsCesA and OsCsl， each containing 11 members. The family members were distributed on 11 chromosomes except chromosome 11. There were 2 sets of tandem repeat genes in rice， and there was better collinearity between rice and maize. OsCesA/Csl members had different tissue expression patterns， and each member responded to jasmonic acid， abscisic acid， gibberellin and auxin treatment in different degrees. Above results laid a foundation for further exploring the specific function of OsCesA/Csl gene family in the growth and development of rice.
