CHEMICAL CONTENTS IN FRUITS OF TRANSGENIC TOMATO CARRYING THE TMV COAT PROTEIN GENE, NONTRANSGENIC TOMATO, AND OTHER LYCOPERSICON SPECIES

Sugars, organic acids, amino acids, and vitamin C contents in the frui ts of transgenic tomato carrying the TMV coat protein gene, nontransge nic tomato, cultivated species of tomato and their wild relatives were measured. The levels of vitamin Ba,dietary fiber, and glutathione in the fruits of transgenic tomato and nontransgenic tomato were also com pared. 1. The results showed no significant differences in these chemi cal components between the fruits of transgenic and nontransgenic toma toes. L. peruvianum and L. hirsutum had much high concentrations of su crose then the other species. The vitamin C and aspartic acid contents in fruits of transgenic tomato, the nontransgenic tomato and L. peruv ianum were considerably higher than they were in the other species, wh ereas the gamma-aminobutyric acid content was comparatively lower. L. cheesmanii had considerably higher glutamic acid, asparagine, and glut amine content than the other species had.
