Taxonomic range of the sequence conservation of the CPuORF families. The blue, yellow, red, green, and purple lines show the conservation range of CPuORF HGs determined by applying ESUCA to Arabidopsis (Arabidopsis thaliana), rice (Oryza sativa), tomato (Solanum lycopersicum), poplar (Populus trichocarpa), and grape (Vitis vinifera) genomes, respectively. The presence of a line within a cell in each taxonomic category indicates the presence of uORF-tBLASTn and mORF-tBLASTn hits for any of the CPuORFs that belong to each HG. In taxonomic categories with a category name with an asterisk, uORF-tBLASTn and mORF-tBLASTn hits found in lower taxonomic categories were excluded. In the case where no uORF-tBLASTn and mORF-tBLASTn hit was found in the taxonomic category that contain a species from which the original uORF was derived, the line showing the species was still drawn in the cell of the taxonomic category because this category contained the species with the original uORF. Arabidopsis, rice, tomato, poplar and grape belong to malvids, commelinids, lamiids, fabids and eudicots*, respectively. HG1-HG53 are previously identified HGs, except for HG2.2, HG9.2, HG16.2, HG43.2, HG50.2 and HG52.2, whereas HG2.2, HG9.2, HG16.2, HG43.2, HG50.2, HG52.2, HG54-HG83, HG86-HG130 and HG149–151 are newly identified HGs
