Genome-Wide Analysis of WOX Multigene Family in Sunflower (Helianthus annuus L.).

ABSTRACT: The WUSCHEL-related homeobox (WOX) is a family of specific transcription factors involved in plant development and response to stress, characterized by the presence of a homeodomain. This study represents the first comprehensive characterization of the WOX family in a member of the Asteraceae family, the sunflower (H. annuus L.). Overall, we identified 18 putative HaWOX genes divided by phylogenetic analysis in three major clades (i.e., ancient, intermediate, and WUS). These genes showed conserved structural and functional motifs. Moreover, HaWOX has homogeneously distributed on H. annuus chromosomes. In particular, 10 genes originated after whole segment duplication events, underpinning a possible evolution of this family along with the sunflower
