Sequence characterization and genetic mapping of the MdMYB3 gene in apple. A) Genomic structure of MdMYB3 gene in apple. The black and gray boxes indicate exons and un-translated region (UTR). SSR1 and SSR2 represent simple sequence repeats, and are present in 5′-UTR and the last exon, respectively. B) The identification of polymorphism of SSR1 and SSR2 loci between Co-op 16 and Co-op 17. The SSR1 locus has been successfully used to develop gene-tagged marker for MdMYB3 in apple. C) Segregation of SSR1 locus among F1 progenies derived from a cross between 'Co-op 16′ x ′Co-op 17′. The F1 population consists of 142 individuals and only partial individuals are presented. D) MdMYB3 gene, highlighted in shaded area, is anchored onto linkage group 15 based on the segregation of SSR1 locus among F1 population of 'Co-op 16′ x 'Co-op 17′ cross.
