Expression of ethylene-regulated tomato ripening genes



Expression of ethylene-regulated tomato ripening genes



International symposium on plant molecular biology: L8



A ripening mutant homozygous for the mutant gene rin on chromosome 5 failed to synthesize lycopene and ethylene. Trace amounts of polygalacturonase (1%) were detected in very mature fruit; the fruit lacked pTOM6 mRNA, which encodes polygalacturonase, and were deficient in several ripening-related mRNAs. Nr/Nr fruit, carrying a mutation on chromosome 9, showed reduced synthesis of ethylene, polygalacturonase and lycopene.
