摘要：WUSCHEL-related homeobox (WOX) transcription factors are plant-specific members that characterized by the presence of a homeodomain. It has been shown that WOX members regulate several aspects of plant development, but the biological functions of this CsWOX gene family remain largely unknown in cucumber (Cucumis sativus L.). In this study, we identified and characterized 11 putative CsWOX genes in cucumber, which are also divided into three major clades (e.g., the Ancient clade, the Intermediate clade and the WUS clade). Expression pattern analysis revealed tissue-specific expression patterns of CsWOX genes, including that CsWOX9 is mainly expressed in developing fruit and also has lower expression in tip and axillary bud, which was further confirmed by in situ hybridization assay. Moreover, overexpression of CsWOX9 in Arabidopsis led to increased branches and rosette leaves, and shorter siliques. Together, these results indicated that CsWOX members may regulate cucumber growth and development.
