AI Article Synopsis
- Basic leucine zipper (bZIP) transcription factors (TFs) play a crucial role in regulating plant development and the synthesis of secondary metabolites like anthocyanins, which contribute to the red bark of the cultivar 'Gantong 1'.
- A total of 89 genes encoding CcbZIP TFs were identified, categorized into 14 subfamilies, and CcbZIP38 and CcbZIP57 were found to be highly expressed in the bark and leaves during various growth stages.
- Analysis suggests that these bZIP TFs may indirectly regulate anthocyanin synthesis, enhancing our understanding of the genetic factors that impact the ornamental traits of plants.
Article 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 .
