摘要： [目的]获取紫背天葵花青素合成代谢核心酶系列信息，为进一步从事紫背天葵或其他特色植物中花青素合成代谢相关基础研究提供依据。[方法]以紫背天葵为材料，以其近缘种白子菜为对照，进行转录组测序分析。[结果]在获取的80 798条单基因簇中，通过8个数据库比对分析，共有43 369条注释到相关信息。这些单基因簇在NR及Swiss-Prot这2个数据库中注释到花青素合成代谢相关系列酶为104个，具体包括10个查尔酮合成酶、5个查尔酮异构酶、36个黄烷酮3-羟化酶、19个二氢黄酮醇4-还原酶、9个花青素合成酶和25个类黄酮3-O-糖基转移酶。通过FPKM均值统计分析可知，这6大家族酶在该两种野菜中表达量差异明显的分别有1、1、3、4、2、4个。在这15个差异表达明显基因中，上调基因7个、下调基因8个。[结论]获取的紫背天葵及其近缘种白子菜中的104个相关酶系列信息中，有15个与紫背天葵花青素合成代谢密切相关。

Abstract: [Objective] The core enzymes in anthocyanin anabolism were investigated,to provid a reference for further studies on the anthocyanin metabolism of G. bicolor and similar plants.[Method]Transcriptome of Gynura bicolor and G. divaricata were sequenced using the Illumina HiSeq 2 500 platform for the study.[Result] The Denovo mapping on 8 databases showed that 43 369 out of 80 798 unigenes annotated differences between the two wild vegetables. Among them, 104 unigenes were identified to relate to the anthocyanin anabolism based on two databases on the non-redundant and Swiss-Prot proteins. They included 10 chalcone synthases, 5 chalcone isomerases, 36 flavanone 3-hydroxylases, 19 dihydroflavonols, 9 anthocyanidin synthases, and 25 flavonoid 3-O-glucosyl transferases. According to the average FPKMs, 7 of the 15 differentially expressed genes (i.e., 1, 1, 3, 4, 2, and 4 genes from each of the 6 enzyme categories) between the 2 wild vegetables were found to be up-regulated, and 8 down-regulated.[Conclusion] There were 15 enzymes in the 104 unigenes appeared to closely associate with the anthocyanin synthesis in G. bicolor and G. divaricata.
