Sugars, organic acids, amino acids, and vitamin C contents in the fruits of transgenic tomato carrying the TMV coat protein gene, nontransgenic tomato, cultivated species of tomato and their wild relatives were measured. The levels of vitamin B2, dietary fiber, and glutathione in the fruits of transgenic tomato and nontransgenic tomato were also compared. (1) The results showed no significant differences in these chemical components between the fruits of transgenic and nontransgenic tomatoes. L. peruvianum and L. hirsutum had much high concentrations of sucrose then the other species. The vitamin C and aspartic acid contents in fruits of transgenic tomato, the nontransgenic tomato and L. peruvianum were considerably higher than they were in the other species, whereas the gamma-aminobutyric acid content was comparatively lower. L. cheesmanii had considerably higher glutamic acid, asparagine, and glutamine content than the other species had
