Abstract

The WUSCHEL-related homeobox (WOX) gene family has a critical effect on plant development and abiotic stress. However, there have been no genome-wide studies on WOX genes within sweet cherry (Prunus avium L.). In the present work, eight PavWOX genes were discovered within sweet cherry at the genome-wide level, and they were mapped to six chromosomes. Based on phylogenetic relationships, these genes were classified into three groups, with genes in one group having similar gene structures and conserved motifs. Meanwhile, the PavWOX genes possessed cis-acting elements and functions associated with hormone responses, stress responses, and development. As revealed by expression patterns, certain PavWOX genes are specifically expressed within tissues, suggesting that they may have unique functions. Additionally, the gene family expression patterns under drought stress were analyzed. PavWOX4, PavWOX5, PavWOX13A, and PavWOX13B had increased expressions upon drought stress. In addition, the transcription factor of PavWOX4 and PavWOX13A was localized in the nucleus, confirming the estimated results. Our findings lay the foundation for determining the expression patterns and functions of the PavWOX gene family within sweet cherry and shed more light on the underlying regulatory mechanisms.
