Abstract

Lagerstroemia indica is a summer ornamental flowering tree, belonging to the Lythraceae family. Its flower color is a key ornamental characteristic. Recent research indicates that WRKY and bZIP transcription factors play important role in flower color formation. Based on the transcriptome database of L. indica, this study identified 85 LibZIPs and 61 LiWRKYs from the L. indica transcriptome database and analyzed their expression profiles using qRT-PCR. Phylogenetic analysis divided LibZIPs into 11 subfamilies and LiWRKYs into six subfamilies. Nine LibZIPs and four LiWRKYs were found to have higher expression in colored samples compared to the white sample. LibZIP31, LibZIP65, LibZIP34, LiWRKY16, LiWRKY25, LiWRKY40, and LiWRKY67 may play important roles in flower color formation in L. indica. These results provide valuable information for further functional analysis of the bZIP and WRKY genes families in L. indica and help clarify their roles in flower color formation.

花青素生物合成过程中 bZIP 和 WRKY 基因家族的鉴定和表达分析

Lagerstroemia indica 是一种夏季观赏花木，属于杓兰科。其花色是主要的观赏特征。最新研究表明，WRKY 和 bZIP 转录因子在花色形成中起着重要作用。本研究以杓兰转录组数据库为基础，从杓兰转录组数据库中鉴定了 85 个 LibZIP 和 61 个 LiWRKY，并利用 qRT-PCR 分析了它们的表达谱。系统进化分析将 LibZIPs 分成 11 个亚科，LiWRKYs 分成 6 个亚科。与白色样本相比，9 个 LibZIPs 和 4 个 LiWRKYs 在有色样本中的表达量更高。LibZIP31、LibZIP65、LibZIP34、LiWRKY16、LiWRKY25、LiWRKY40 和 LiWRKY67 可能在籼稻花色形成中发挥重要作用。这些结果为进一步对籼稻中的 bZIP 和 WRKY 基因家族进行功能分析提供了有价值的信息，并有助于明确它们在花色形成中的作用。
