The Slmyb12-Δy allele in the pf mutants. A, SlMYB12 gene expression levels (FPKMs) in RNA-Seq analysis for both Δy mutants and the wild type. B, SlMYB12 genomic region and RNA-Seq read mapped gene expression profile. The two genes placed downstream of SlMYB12 in the genome are also shown. C, SlMYB12 PCR amplicons using genomic DNA (gDNA) templates from the wild type, Δy1, and Δy2 mutants. See both size and location of the PCR reactions in D. D, SlMYB12 genomic sequence (available in tomato database: http://www.solgenomics.net/) and the PCR/RT-PCR oligonucleotide distribution in the gene sequence. The location of the putative deletion in SlMYB12 is indicated by a red asterisk. MFR, Myb-like flavonol regulation motif; SG7, subgroup 7 with the flavonol regulation motif; SG7-2, subgroup 7-2 with the specific flavonol regulation motif.
