Mutation in FvPAL2 leads to light red strawberry fruits and yellow-green petioles.

In recent years, light red or white strawberries have attracted much attention because of their unusual color, however, the mechanism of strawberry color formation, especially light red strawberry color, is not well understood. By EMS mutagenesis of woodland strawberry (Fragaria vesca), we identified two mutants, rg40 and rg120, with light red fruit and yellow-green petiole, and allelic hybridization and BSA mixed-pool sequencing revealed that the phenotype was caused by mutation in the FvPAL2 protein in the anthocyanin synthesis pathway. Enzyme activity experiments showed that the mutant FvPAL2 protein barely catalyzed the substrate conversion normally, thus blocking anthocyanin synthesis, which in turn led to a decrease in anthocyanin accumulation in fruits and petioles.
