a Fluorescence microscopy of self-pollinated styles of SI (left) and SC (right) genotypes shows that self-pollen can grow through the styles of SC genotypes, while self-pollen tube growth is arrested in styles from SI plants. Although a few self-pollen tubes reach the end of the style in the SI genotype, these do not induce a berry set. These images are typical for SI and SC genotypes as evidenced in 50 or more similar genotypes. b The LOD profile resulting from QTL analysis in population 17SC11 shows a highly significant QTL on the distal end of chromosome 12. c Recombinant analysis suggests Sli must be located in an 12.6 kb interval, which contains two genes. The SC haplotype is shown in green, the SI haplotype is shown in red. Numbers above the haplotypes are the positions of the genotyped SNP markers on chromosome 12 of DM4.04. d Candidate gene PGSC0003DMG400016861 shows an SC-specific 533 nt insertion in the promoter, suggesting that the SC allele of PGSC0003DMG400016861 may show altered tissue-specific expression. The Sli-specific amino acid changes and their positions are shown below the gene model.
