Identification of the WUSCHEL-Related Homeobox (WOX) Gene Family, and Interaction and Functional Analysis of TaWOX9 and TaWUS in Wheat.

ABSTRACT: The WUSCHEL-related homeobox (WOX) is a family of plant-specific transcription factors, with important functions, such as regulating the dynamic balance of division and differentiation of plant stem cells and plant organ development. We identified 14 distinct TaWOX genes in the wheat (Triticum aestivum L.) genome, based on a genome-wide scan approach. All of the genes under evaluation had positional homoeologs on subgenomes A, B and D except TaWUS and TaWOX14. Both TaWOX14a and TaWOX14d had a paralogous copy on the same genome due to tandem duplication events. A phylogenetic analysis revealed that TaWOX genes could be divided into three groups. We performed functional characterization of TaWOX genes based on the evolutionary relationships among the WOX gene families of wheat, rice (Oryza s
