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.
WUSCHEL 相关同源盒（WOX）转录因子（TFs）在调节植物发育和响应各种非生物胁迫方面发挥着关键作用。然而，在 中WOX 蛋白的成员和功能仍不清楚。在这项研究中，共鉴定出 11 个 WOX 基因，并使用生物信息学方法进行了初步鉴定和分析。系统发育树表明，大多数 PmWOX 分布在古老和 WUS 进化枝中，只有一个成员在中间进化枝中发现。我们选择了植物中四个高度保守的 基因进行进一步的表达分析。这些基因在几乎所有组织中都有表达，而 、 、 在愈伤组织中表达水平较高，表明它们可能参与愈伤组织发育过程中的特定功能。不同非生物胁迫下的表达模式表明 可能参与 抵抗多种胁迫。对 的鉴定和初步分析为进一步研究 对非生物胁迫的抗性分子机制奠定了基础。
