Genome-Wide Identification and Expression Profiling of the WOX Gene Family in Citrus sinensis and Functional Analysis of a CsWUS Member.

ABSTRACT: WUSCHEL-related homeobox (WOX) transcription factors (TFs) are well known for their role in plant development but are rarely studied in citrus. In this study, we identified 11 putative genes from the sweet orange genome and divided the citrus WOX genes into three clades (modern/WUSCHEL(WUS), intermediate, and ancient). Subsequently, we performed syntenic relationship, intron-exon organization, motif composition, and cis-element analysis. Co-expression analysis based on RNA-seq and tissue-specific expression patterns revealed that CsWOX gene expression has multiple intrinsic functions. CsWUS homolog of AtWUS functions as a transcriptional activator and binds to specific DNA. Overexpression of CsWUS in tobacco revealed dramatic phenotyp
