DFR — Solanum lycopersicum

Summary

SOLYC02G085020.4, the tomato DFR gene on chromosome 2, encodes a protein with flavanone 4-reductase, dihydroflavanol 4-reductase, chalcone isomerase, naringenin-chalcone synthase, and flavonol synthase activities. It is associated with anthocyanin accumulation and biosynthesis, flavonoid and proanthocyanidin biosynthesis, and pigment accumulation. The gene has been linked to fruit and leaf color, stigma color, carotene and carotenoid content, photosynthetic ability and net photosynthetic rate, water use efficiency, sugar and starch content, lignin content, and responses to UV light, low temperature, oxidative stress, and salinity. It is also linked to seed dormancy, stamen morphology, flower development, root phototropism, and insect damage response. The protein localises to the cytosol, nucleus, endoplasmic reticulum, and tonoplast.
