Polysaccharide is a quality marker of Polygonatum odoratum, which has significant pharmacological effects in immune regulation and anti-tumor. As one of the key enzymes in polysaccharide synthesis, sucrosesynthase (SUS) has always been an important research field to reveal the synthesis of plant polysaccharides. Based on transcriptom data of Polygonatum odoratum, the SUS gene family members were identified by bioinformatics, and their expression profiling were analyzed using qPCR. The results showed that eight PoSUS gene were identified, their protein ranged from 111 to 310 amino acid residues (aa) in length, and relative molecular weight varied from 12.81 kDa to 35.43 kDa, isoelectric point (pI) in the range of 5.83 to 9.18; phylogenetic analysis indicated that eight PoSUS genes were divided into 3 subfamily, and the subfamily Ⅲ included the largest PoSUS genes family member; subcellural localization analysis showed that most of PoSUS proteins were located in chloroplast. Additionally, expression patterns analysis revealed that PoSUS1 and PoSUS6 genes were preferably expressed in rhizome, and the transcript levels of PoSUS1 and PoSUS2 were higher in high-polysaccharide cultivar HN1 than those in a low-polysaccharide cultivar AH2. In addition, the CDS of PoSUS1 gene were cloned from HN1 and AH2, there are three amino acid difference between HN1 and AH2, which located in sucrose synthase domain. Our findings can laid a basis for the further study of functional analysis of SUS genes, and provided a theoretical basis for analyzing molecular mechanism of the formation mechanism of medicinal quality of Polygonatum odoratum.

多糖是玉竹的质量标志物,在免疫调节、抗肿瘤等方面具有显著的药理作用。作为多糖合成的关键酶之一,蔗糖合成酶(sucrose synthase, SUS)一直是揭示植物多糖合成的重要研究内容。基于转录组序列信息,本研究利用生物信息学手段对玉竹SUS基因家族及其成员进行鉴定,并利用荧光定量PCR(qPCR)对其成员表达模式进行分析。结果表明:玉竹转录组共获得8个具有ORF序列的PoSUS基因家族成员,其编码蛋白质含有111~310个氨基酸,分子量为12.81~35.43 kDa,其理论等电点为5.83~9.18。系统进化树分析表明,8个PoSUS基因家族成员可分为3个亚家族,其中第Ⅲ亚家族基因成员数目最多。亚细胞定位预测显示大多数PoSUS蛋白定位在叶绿体。基因表达模式分析表明,PoSUS1PoSUS6基因在多糖积累的根茎组织中表达量最高,且高多糖种质HN1中PoSUS1PoSUS2表达量显著高于低多糖种质AH2。此外,本研究还从种质HN1和AH2克隆得到PoSUS1基因CDS序列,其编码蛋白在2份种质间存在3处氨基酸差异,且这些差异位于PoSUS1蔗糖合成酶结构域。本研究结果为深入研究玉竹SUS基因功能奠定基础,也为玉竹药用品质形成分子机制研究提供理论依据。

多糖是玉竹的质量标志物,在免疫调节、抗肿瘤等方面具有显著的药理作用。作为多糖合成的关键酶之一,蔗糖合成酶(sucrose synthase, SUS)一直是揭示植物多糖合成的重要研究内容。基于转录组序列信息,本研究利用生物信息学手段对玉竹SUS基因家族及其成员进行鉴定,并利用荧光定量PCR(qPCR)对其成员表达模式进行分析。结果表明:玉竹转录组共获得8个具有ORF序列的PoSUS基因家族成员,其编码蛋白质含有111~310个氨基酸,分子量为12.81~35.43 kDa,其理论等电点为5.83~9.18。系统进化树分析表明,8个PoSUS基因家族成员可分为3个亚家族,其中第Ⅲ亚家族基因成员数目最多。亚细胞定位预测显示大多数PoSUS蛋白定位在叶绿体。基因表达模式分析表明,PoSUS1PoSUS6基因在多糖积累的根茎组织中表达量最高,且高多糖种质HN1中PoSUS1PoSUS2表达量显著高于低多糖种质AH2。此外,本研究还从种质HN1和AH2克隆得到PoSUS1基因CDS序列,其编码蛋白在2份种质间存在3处氨基酸差异,且这些差异位于PoSUS1蔗糖合成酶结构域。本研究结果为深入研究玉竹SUS基因功能奠定基础,也为玉竹药用品质形成分子机制研究提供理论依据。

Polysaccharide is a quality marker of Polygonatum odoratum, which has significant pharmacological effects in immune regulation and anti-tumor. As one of the key enzymes in polysaccharide synthesis, sucrosesynthase (SUS) has always been an important research field to reveal the synthesis of plant polysaccharides. Based on transcriptom data of Polygonatum odoratum, the SUS gene family members were identified by bioinformatics, and their expression profiling were analyzed using qPCR. The results showed that eight PoSUS gene were identified, their protein ranged from 111 to 310 amino acid residues (aa) in length, and relative molecular weight varied from 12.81 kDa to 35.43 kDa, isoelectric point (pI) in the range of 5.83 to 9.18; phylogenetic analysis indicated that eight PoSUS genes were divided into 3 subfamily, and the subfamily Ⅲ included the largest PoSUS genes family member; subcellural localization analysis showed that most of PoSUS proteins were located in chloroplast. Additionally, expression patterns analysis revealed that PoSUS1 and PoSUS6 genes were preferably expressed in rhizome, and the transcript levels of PoSUS1 and PoSUS2 were higher in high-polysaccharide cultivar HN1 than those in a low-polysaccharide cultivar AH2. In addition, the CDS of PoSUS1 gene were cloned from HN1 and AH2, there are three amino acid difference between HN1 and AH2, which located in sucrose synthase domain. Our findings can laid a basis for the further study of functional analysis of SUS genes, and provided a theoretical basis for analyzing molecular mechanism of the formation mechanism of medicinal quality of Polygonatum odoratum.
