Additional file 3: Figure S2. of Overexpression of PaNAC03, a stress induced NAC gene family transcription factor in Norway spruce leads to reduced flavonol biosynthesis and aberrant embryo development

Schematic representation of the PaLAR3A promoter (Genbank accession no. KX574229.1) in black and the PaLAR3B promoter (KX574230.1) in red, the white regions in PaLAR3B promoter corresponds to deletions in the sequence compared to PaLAR3A promoter. The two NAC binding sites (TTTCGT) present in the region unique to the PaLAR3A promoter are indicated in yellow. In the PaLAR3A_mut promoter it is only these two sites which has been mutated in the remainder of the PaLAR3A promoter is intact. (XLSX 69Â kb)

本示意图以黑色标注PaLAR3A启动子（promoter），其GenBank登录号为KX574229.1；以红色标注PaLAR3B启动子（KX574230.1）。相较于PaLAR3A启动子，PaLAR3B启动子中的白色区域对应其序列缺失片段。PaLAR3A启动子特有序列区域内存在的两个NAC结合位点（TTTCGT）以黄色标注。PaLAR3A突变型启动子仅对这两个位点进行了突变，其剩余序列均保持完整。（XLSX 69 KB）
