Identification and expression analysis of the genes under different nitrogen and carbon dioxide treatments in .

UNLABELLED

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.
