Large SVs upstream from CsFT in different cucumber populations. A, Schematic illustration of SVs giving rise to the short-1, short-2, and long types URs of CsFT. The 39.9- and 16.2-kb deletions are designated as deletion-1 and deletion-2, respectively. The gray arrow shapes represent the annotated genes, and the transposase is labeled with a red rectangle. B, Maximum-likelihood phylogeny of the 4.5-kb gene body regions and 16.5-kb URs of CsFT from 115 cucumber accessions. Blue, red, and yellow circles denote long, short-2, and short-1 type URs of CsFT, respectively. The bootstrap values are shown at the nodes (%). The numbers on the circular lines indicate the proportions of cucumber accessions from different subgroups in each branch.
