Pectin is one of the most important components of the plant cell wall. Galacturonosyltransferase-like (GATL) is an important enzyme involved in forming pectin in . In this study, 12 genes were identified and characterized based on the genome using bioinformatics methods. The results showed that the PtGATLs contained four typical motifs, including DXD, LPPF, GLG, and HXXGXXKPW. According to phylogenetic analysis, PtGATLs were divided into six groups. Chromosome distribution and genome synteny analysis showed that there were 11 segmental-duplicated gene pairs with repeated fragments on chromosomes 2, 5, 7, 8, 10, and 14. Tissue-specific expression profiles indicated that these had different expression patterns. The transcription level of was regulated by different carbon dioxide and nitrogen concentrations. In conclusion, the identification and analysis of genes in poplar provide important information on the gene function.

果胶是植物细胞壁最重要的成分之一。类半乳糖醛酸基转移酶（GATL）是参与果胶形成的一种重要酶。在本研究中，基于基因组利用生物信息学方法鉴定并表征了12个基因。结果表明，PtGATL包含四个典型基序，包括DXD、LPPF、GLG和HXXGXXKPW。根据系统发育分析，PtGATL被分为六组。染色体分布和基因组共线性分析表明，在第2、5、7、8、10和14号染色体上存在11对具有重复片段的片段重复基因对。组织特异性表达谱表明这些基因具有不同的表达模式。其转录水平受不同二氧化碳和氮浓度的调控。总之，杨树中该基因的鉴定和分析为基因功能提供了重要信息。
