Research on gene expression of MYB transcription factor related to tomato fruit color

During the tomato fruit color development, transcription factor may play important roles. From an introgression line population derived from tomato wild species Solanum lycopersicoides, we found a yellow-fruit mutant line which was different from redfruit patent. We took red-fruit parent tomato and yellow-fruit mutant as genetic materials to study the gene expression profiles of MYB transcription factor by digital gene expression sequencing and RT-PCR. As results, we screened out many MYB transcription factors related to tomato fruit color and differential expressed in yellow-fruit and red-fruit tomato, and verified one of them by RT-PCR.
