Paralleling Calgene’s efforts to develop the PG-antisense tomato lines, the company began to gain experience in the conventional fresh-market tomato business and to meet with community leaders, media representatives and consumers in Davis and Chicago, the two sites selected for initial introduction of the Dlavr SAVR tomato.

The failure of the Flavr Savr has been attributed to Calgene’s inexperience in the business of growing and shipping tomatoes. Potential promoter or enhancer elements associated with this gene may be associated with transcription across the T-DNA locus and could be responsible for contributing to the initial production of a dsRNA for the coding regions, thus resulting in the production of the siRNAs. Bands were observed in the transgenic plants of and bp corresponding to the PG region of the locus, in addition to a 2-kb band of the native PG gene present in all lanes.
