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.

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OsCesAOsCsl,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。
