Developmental regulation of peach ACC oxidase promoter--GUS fusions in transgenic tomato fruits.


A genomic DNA sequence (PpACO1) encoding 1-aminocyclopropane-1-carboxylic acid oxidase (ACO) from peach (Prunus persica L. Batsch cv. Loring) was isolated. It has four exons interrupted by three introns and 2.9 kb of flanking region 5' of the translational start codon. Previous work with the cDNA demonstrated that accumulation of the peach ACO message… (More)
