摘要:
为探索芋淀粉合成机理,本研究从靖江香沙芋中克隆获得了3个芋可溶性淀粉合酶(CeSS)家族基因。3个基因CeSSI、CeSSII、CeSSIII碱基序列全长分别为1 932 bp、2 409 bp 、3 606 bp,编码形成3个亲水性蛋白质。系统进化分析结果显示,3个蛋白质CeSSI、CeSSII、CeSSIII与海枣、芦笋、药用稻等单子叶植物的亲缘关系较近。表达分析结果表明,这3个CeSS基因广泛存在于芋的叶片、叶柄、母芋和子芋中。 CeSSI和CeSSII的表达水平随芋球茎的发育而显著增加,在种植150 d达到峰值,而CeSSIII在成熟后期(种植180 d)的芋球茎中表达量较高。
Abstract:
To explore the mechanism of starch synthesis in taro, three genes of soluble starch synthase (CeSS) family were isolated from Jingjiang Xiangsha taro. The three genes, CeSSI, CeSSII and CeSSIII, were 1 932 bp, 2 409 bp and 3 606 bp in length, respectively, and encoded three hydrophilic proteins. Phylogenetic analysis results showed that three proteins, CeSSI, CeSSII and CeSSIII, were closely related to monocotyledonous plants such as date palm, asparagus and medicinal wild rice. The results of expression analysis indicated that these three CeSS genes were widely existed in leaves, petioles, main corms and lateral cormels of taro. The expression levels of CeSSI and CeSSII increased significantly with the development of taro corms, and reached the peak at 150 d after planting, while the expression level of CeSSIII was higher in taro corms at the late maturity stage (180 d after planting).
