|a The NAC transcription factor family is essential for plant growth, development, and stress responses. This study, based on RNA-Seq data from 84K poplar and weighted gene co-expression network analysis (WGCNA), identified PagNAC17 as a key factor in the salt stress response of poplar. A total of 202 PtrNAC TFs were identified and categorized into two major subfamilies, with their conserved motifs, gene structures, and cis-acting elements analyzed. Genes co-expressed with PagNAC17 are involved in energy metabolism, such as photosynthesis (e.g., light absorption and CO2 fixation), oxidative phosphorylation, signal transduction processes, and stress responses (e.g., the glutathione metabolism pathway), suggesting that PagNAC17 may regulate salt tolerance in poplar through these pathways. PagNAC17 is localized in the nucleus, primarily expressed in young leaves with the lowest expression in roots, and has transcriptional activation activity. The expression of PagNAC17 in yeast significantly enhances growth under salt conditions. Likewise, the overexpression of PagNAC17 in 84K poplar also significantly enhances salt tolerance, reducing yellowing, wilting, and oxidative damage. In summary, PagNAC17 is a key salt-tolerance regulator within the poplar NAC gene family. This study provides valuable insights for functional research on the NAC TFs family and offers a promising genetic resource for the salt-tolerance breeding of poplar
