摘要	The WUSCHEL-related homeobox (WOX) proteins are a class of transcription factors exclusive to plants. They can promote cell division or inhibit stem cell differentiation to regulate plant growth and development. However, the WOX transcription factor genes in the monocotyledon Dendrobium catenatum Lindl. remain relatively uncharacterized. Specifically, the effects of phytohormones on their expression levels are unclear. In this study, we identified and analyzed 10 candidate DcaWOX transcription factor genes in D. catenatum. The DcaWOX family was divided into the modern/WUS, intermediate, and ancient clades. The subcellular localization analysis detected DcaWOX-GFP fusion proteins in the tobacco epidermal leaf cell nucleus. In DcaWOX, members of the WUS clade with the WUS-box motif can significantly activate the expression of TPL in vivo, while members of the intermediate and ancient clades cannot. The expression of the DcaWOX genes varied among the examined tissues. Moreover, the DcaWOX expression patterns were differentially affected by the phytohormone treatments, with differences detected even between homologs of the same gene. Furthermore, the gene expression patterns were consistent with the predicted cis-acting elements in the promoters. The above results suggest that DcaWOX may have an important role in its growth and development and resistance to stress. The results of this comprehensive investigation of the DcaWOX gene family provide the basis for future studies on the roles of WOX genes in D. catenatum.
