Ethylene biosynthesis regulation in tomato fruit from the F1 hybrid of the ripening inhibitor (rin) mutant.
We have previously shown a significant decrease in the ethylene production in tomato fruit from the RIN/rin genotype. In this present study, we evaluated the amount of 1-aminocyclopropane-1-carboxylic acid (ACC) and the gene expression and enzymatic activities of ACC synthase (ACS) and ACC oxidase (ACO) to find which type of regulation influenced this low ethylene production. The results suggest that the decreased ethylene production was due to transcriptional regulation of the ACS and ACO genes by the heterozygous effect of the rin gene.
