Fig. 2. RNA sequencing of germinated pollen from SC and SI genotypes.
a Expression of several pollen-expressed genes on chromosome 12. Candidate gene PGSC0003DMG400016861 (black arrow) is expressed in pollen from SC genotypes, but not in pollen from SI genotypes, whereas other pollen-expressed genes show similar expression levels in SC and SI genotypes. The color scale is based on FPKM values relative to the highest expressing genotype, ranging from green (highest expression) to red (lowest expression). * For these two genes the RNA-seq reads were mapped to the corresponding tomato gene model. ** For this gene the RNA-seq reads were mapped to the corresponding pepper gene model. *** Gene model CA05g06620 was inferred from Pepper and lacks a predicted counterpart in the PGSC gene catalog. b Phylogenetic tree of the 533 bp insertion and homologous sequences in potato. The 533 bp insertion in the SC allele of Sli is indicated with the arrow.
