The ubiquitin fusion degradation 1 protein (UFD1) is an important ubiquitin recognition<br />
component in the ubiquitin-mediated degradation pathway of animals <strong>and</strong> yeast, but information<br />
about its occurrence <strong>and</strong> role in plants is scarce. Three putative UFD1 genes from grape were<br />
identified in this study. The data were confirmed by searching the publishing database from two<br />
independent grape genome projects <strong>with</strong> the obtained sequences. Three putative UFD1 genes<br />
containing the evolutionarily conserved UFD1 domains at the N-terminus were found on<br />
chromosome 3, chromosome 6 <strong>and</strong> chromosome 12, suggesting the presence of UFD1 genes in<br />
grapevine. These genes were compared <strong>with</strong> those in Arabidopsis, poplar, rice, wheat <strong>and</strong> maize<br />
through genome <strong>and</strong> EST databases mining. Unlike monocot species, having two UFD1 genes,<br />
dicot species have three UFD1 genes. Phylogeneically, the UFD1-like proteins from these six<br />
higher angiosperms fall into two distinct orthologous groups, which each includes a monocot<br />
clade <strong>and</strong> a dicot clade. One of the UFD1 paralogs in grape, Arabidopsis, <strong>and</strong> poplar has been<br />
duplicated through a segmental duplication event.<br />
