Abstract

Basic leucine zipper (bZIP) transcription factors (TFs) regulate plant development, growth, and secondary metabolism. The formation of red bark of new ornamental cultivar 'Gantong 1' is regulated mainly by anthocyanin anabolism. However, it is unclear whether and which bZIP TFs are involved in this process. We identified 89 genes encoding CcbZIP TFs in genome that could be divided into 14 subfamilies with similar gene structures and conserved motifs. CcbZIP38 and CcbZIP57 were highly conserved compared to HY5 in and they were highly expressed in the bark and leaves of 'Gantong 1' at different stages. The target gene enrichment analysis showed that indicating indirect involvement of CcbZIP38 and CcbZIP57 in the regulation of anthocyanin synthesis. Our study contributes to understanding the molecular mechanism of anthocyanin synthesis regulation by CcbZIP TFs and provides a theoretical basis for genetic improvement of ornamental traits in .

摘要

碱性亮氨酸拉链（bZIP）转录因子调控植物的发育、生长和次生代谢。新观赏品种‘甘桐1号’红色树皮的形成主要受花青素合成代谢调控。然而，尚不清楚是否有bZIP转录因子以及哪些bZIP转录因子参与这一过程。我们在基因组中鉴定出89个编码CcbZIP转录因子的基因，这些基因可分为14个亚家族，具有相似的基因结构和保守基序。与拟南芥中的HY5相比，CcbZIP38和CcbZIP57高度保守，且它们在‘甘桐1号’不同发育阶段的树皮和叶片中高表达。靶基因富集分析表明，CcbZIP38和CcbZIP57间接参与花青素合成的调控。我们的研究有助于理解CcbZIP转录因子调控花青素合成的分子机制，并为[具体植物名称未给出]观赏性状的遗传改良提供理论依据。
