Genome-Wide Analysis of the WOX Family and Its Expression Pattern in Root Development of Paeonia ostii.

ABSTRACT: Tree peony (Paeonia suffruticosa Andr.) is a woody plant with high ornamental, medicinal, and oil values. However, its low rooting rate and poor rooting quality are bottleneck issues in the micropropagation of P. ostii. The WUSCHEL-related homeobox (WOX) family plays a crucial role in root development. In this study, based on the screening of the genome and root transcriptome database, we identified ten WOX members in P. ostii. Phylogenetic analysis revealed that the ten PoWOX proteins clustered into three major clades, the WUS, intermediate, and ancient clade, respectively. The conserved motifs and tertiary structures of PoWOX proteins located in the same clade exhibited higher similarity. The analysis of cis-regulatory elements in the promoter indicated that <
