Organizational summary of beet Rf1 loci. Names of alleles are shown at the left with their genetic action in parentheses. Boxes and wedges indicate exons and introns, respectively. Gene directions are from right to left. Names of individual RF-Oma1 are shown above the genes with the old names used in previous papers in parentheses. The 200-kDa generative copies are striped; non-generative copies are open; and a pseudogene is filled. A vertical arrow indicates the position of a premature stop codon. This study characterized orf20_NK-198-4, orf20_NK-198-3, orf20_NK-198-1, orf20_NK-219-3, orf20_NK-219-2 and orf20_{PI 615522}. Sources of other information about these loci are [23, 25,26,27]
