Starch branching enzyme (SBE) play a key role in amylopectin biosynthesis and directly influence the content and structure of starch. Taro is a major tuber crop, widely cultivated in tropical and subtropical regions of the world. At present, there are few studies on SBE in taro, and the number, molecular structural characteristics and expression patterns of SBE genes in taro are not clear. In this study, a comprehensive analysis of taro SBE genes was conducted for the first time, and three SBE genes (CeSBE1, CeSBE2 and CeSBE3) were identified. The amino acid numbers of CeSBE1, CeSBE2 and CeSBE3 proteins was 828, 845 and 598, respectively, with molecular mass of 92 956.71 Da, 95 625.13 Da and 69 169.16 Da, and isoelectric point of 5.22, 5.41 and 7.36, respectively. Phylogenetic analysis showed that the three CeSBE proteins were divided into three different subgroups. Gene structure analysis showed that the number of CeSBE1, CeSBE2 and CeSBE3 exons was 16, 22 and 10, respectively. Conservative structural domain analysis showed that both CeSBE1 and CeSBE2 proteins had α-amylase_C and α-amylase structural domains and 7 motifs, while CeSBE3 protein had α-amylase and CBM_48 structural domains and 3 motifs. Analysis of cis-acting elements in the promoter region of CeSBE gene showed that a total of 55 cis-acting elements were predicted, 29 of which were functionally annotated, involving elements related to light response, hormone response, plant growth and development, and environmental stress. The three CeSBE genes were expressed in all tissues, with CeSBE2 being significantly expressed in corms and leaves (P<0.05). At different developmental stages of the corm, CeSBE2 had high expression at all developmental stages, showing a trend of increasing and then decreasing expression, with peak expression at 120 d of corm development. The increase in total starch and amylopectin content at different developmental stages of the corm was consistent with the trend of CeSBE2 expression, suggesting that CeSBE2 may be a key gene for amylopectin biosynthesis in taro. The study would enhance the understanding of CeSBE gene family members and provide the basis for genetic improvement of yield, quality and nutritional traits in taro.

淀粉分支酶(starch branching enzyme, SBE)在支链淀粉生物合成中发挥关键作用,直接影响淀粉的含量和结构。芋(Colocasia esculenta)是一种主要的块茎类作物,在世界上热带和亚热带地区广泛栽培。目前,SBE在芋中的研究很少,对SBE基因在芋中的数量、分子结构特征和表达模式还不清楚。本研究首次对芋SBE基因进行了全面分析,鉴定了3个SBE基因(CeSBE1CeSBE2CeSBE3)。CeSBE1、CeSBE2和CeSBE3蛋白氨基酸数量分别为828、845和598,分子质量分别为92 956.71、95 625.13、69 169.16 Da,等电点分别为5.22、5.41和7.36。系统进化分析显示3个CeSBE蛋白分别在3个不同的亚群。基因结构分析显示,CeSBE1CeSBE2CeSBE3外显子数量分别为16、22、10;保守结构域分析表明,CeSBE1和CeSBE2均具有alpha-amylase_C和alpha-amylase结构域及7个motif,而CeSBE3具有alpha-amylase和CBM_48结构域及3个motif。CeSBE基因启动子区域顺式作用元件分析表明,共预测到55个顺式作用元件,其中29个具有功能注释,涉及光响应、激素响应、植物生长发育及环境压力等相关元件。在不同组织中,3个CeSBE基因均能在所有组织中表达,其中CeSBE2在球茎和叶片显著表达(P<0.05);在球茎不同发育阶段中,CeSBE2在所有的发育阶段均有较高的表达量,呈现先升高后降低的表达趋势,在球茎发育120 d的表达量达到峰值。球茎不同发育阶段总淀粉和支链淀粉含量增加与CeSBE2表达量趋势一致,说明CeSBE2可能是芋支链淀粉生物合成的关键基因。本研究结果可为芋的产量、品质和营养性状的遗传改良提供基础。

淀粉分支酶(starch branching enzyme, SBE)在支链淀粉生物合成中发挥关键作用,直接影响淀粉的含量和结构。芋(Colocasia esculenta)是一种主要的块茎类作物,在世界上热带和亚热带地区广泛栽培。目前,SBE在芋中的研究很少,对SBE基因在芋中的数量、分子结构特征和表达模式还不清楚。本研究首次对芋SBE基因进行了全面分析,鉴定了3个SBE基因(CeSBE1CeSBE2CeSBE3)。CeSBE1、CeSBE2和CeSBE3蛋白氨基酸数量分别为828、845和598,分子质量分别为92 956.71、95 625.13、69 169.16 Da,等电点分别为5.22、5.41和7.36。系统进化分析显示3个CeSBE蛋白分别在3个不同的亚群。基因结构分析显示,CeSBE1CeSBE2CeSBE3外显子数量分别为16、22、10;保守结构域分析表明,CeSBE1和CeSBE2均具有alpha-amylase_C和alpha-amylase结构域及7个motif,而CeSBE3具有alpha-amylase和CBM_48结构域及3个motif。CeSBE基因启动子区域顺式作用元件分析表明,共预测到55个顺式作用元件,其中29个具有功能注释,涉及光响应、激素响应、植物生长发育及环境压力等相关元件。在不同组织中,3个CeSBE基因均能在所有组织中表达,其中CeSBE2在球茎和叶片显著表达(P<0.05);在球茎不同发育阶段中,CeSBE2在所有的发育阶段均有较高的表达量,呈现先升高后降低的表达趋势,在球茎发育120 d的表达量达到峰值。球茎不同发育阶段总淀粉和支链淀粉含量增加与CeSBE2表达量趋势一致,说明CeSBE2可能是芋支链淀粉生物合成的关键基因。本研究结果可为芋的产量、品质和营养性状的遗传改良提供基础。

Starch branching enzyme (SBE) play a key role in amylopectin biosynthesis and directly influence the content and structure of starch. Taro is a major tuber crop, widely cultivated in tropical and subtropical regions of the world. At present, there are few studies on SBE in taro, and the number, molecular structural characteristics and expression patterns of SBE genes in taro are not clear. In this study, a comprehensive analysis of taro SBE genes was conducted for the first time, and three SBE genes (CeSBE1, CeSBE2 and CeSBE3) were identified. The amino acid numbers of CeSBE1, CeSBE2 and CeSBE3 proteins was 828, 845 and 598, respectively, with molecular mass of 92 956.71 Da, 95 625.13 Da and 69 169.16 Da, and isoelectric point of 5.22, 5.41 and 7.36, respectively. Phylogenetic analysis showed that the three CeSBE proteins were divided into three different subgroups. Gene structure analysis showed that the number of CeSBE1, CeSBE2 and CeSBE3 exons was 16, 22 and 10, respectively. Conservative structural domain analysis showed that both CeSBE1 and CeSBE2 proteins had α-amylase_C and α-amylase structural domains and 7 motifs, while CeSBE3 protein had α-amylase and CBM_48 structural domains and 3 motifs. Analysis of cis-acting elements in the promoter region of CeSBE gene showed that a total of 55 cis-acting elements were predicted, 29 of which were functionally annotated, involving elements related to light response, hormone response, plant growth and development, and environmental stress. The three CeSBE genes were expressed in all tissues, with CeSBE2 being significantly expressed in corms and leaves (P<0.05). At different developmental stages of the corm, CeSBE2 had high expression at all developmental stages, showing a trend of increasing and then decreasing expression, with peak expression at 120 d of corm development. The increase in total starch and amylopectin content at different developmental stages of the corm was consistent with the trend of CeSBE2 expression, suggesting that CeSBE2 may be a key gene for amylopectin biosynthesis in taro. The study would enhance the understanding of CeSBE gene family members and provide the basis for genetic improvement of yield, quality and nutritional traits in taro.
