Genome-wide identification of WOX family members in rose and functional analysis of RcWUS1 in embryogenic transformation.

ABSTRACT: WUSCHEL-related homeobox (WOX) is a class of plant-specific transcription factors and plays vital roles in plant development and evolution. Here, we analyzed WOX family genes of three Rosa species and explored their potential functions in Rosa. A total of 351 WOX genes were identified from Rosa chinensis 'Old Blush' (208), Rosa wichuraiana 'Basye's Thornless' (21) and Rosa rugosa (122). The WOX genes were found to significantly expand in Rosa compared to Arabidopsis. Phylogenetic analysis showed that Rosa WOXs genes were classified into an ancient clade, an intermediate clade, and a WUS clade. Collinearity analysis suggested that gene duplication and purifying selection might be important driving forces in the evolution of WOXs. Expression patterns of WOXs found that higher levels of RcWUS
