Identification and Expression Patterns of Transcription Factors under Abiotic Stresses in .

WUSCHEL-related homeobox (WOX) transcription factors (TFs) play a crucial role in regulating plant development and responding to various abiotic stresses. However, the members and functions of WOX proteins in remain unclear. In this study, a total of 11 WOX genes were identified, and bioinformatics methods were used for preliminary identification and analysis. The phylogenetic tree revealed that most PmWOXs were distributed in ancient and WUS clades, with only one member found in the intermediate clade. We selected four highly conserved genes within plants for further expression analysis. These genes exhibited expressions across almost all tissues, while , , and showed high expression levels in the callus, suggesting their potential involvement in specific functions during callus development. Expression patterns under different abiotic stresses indicated that could participate in resisting multiple stresses in . The identification and preliminary analysis of lay the foundation for further research on analyzing the resistance molecular mechanism of to abiotic stresses.
