摘要

WUSCHEL相关HOMEOBOX 5 (WOX5)是WUSCHEL (WUS)同源域转录因子家族的一员。WOX5主要在静止中心(QC)表达，并在根尖分生组织(RAM)中赋予干细胞身份。与WUS在抑制根分生组织发育中的作用一致，我们发现WOX5的异位表达通过抑制茎相关基因，如YABBY1 (YAB1)来破坏茎的发育。我们的研究结果表明，WOX5和WUS可能赋予不同的组织身份，并分别指定RAM和SAM。

Overexpression of the WOX5 gene inhibits shoot development

ABSTRACT WUSCHEL-RELATED HOMEOBOX 5 (WOX5) is a member of the WUSCHEL (WUS) homeodomain transcription factor family. WOX5 is expressed mainly in the quiescent center (QC) and confers stem cell identity in the root apical meristem (RAM). Consistent with the role of WUS in repressing root meristem development, we found that ectopic expression of WOX5 disrupted shoot development by repressing shoot-related genes, such as YABBY1 (YAB1). Our findings suggest that WOX5 and WUS potentially confer different tissue identities and specify RAM and SAM, respectively.
