ASSESSMENT OF THE MUTAGENICITY OF EXTRACTS OF TMV-COAT-PROTEIN-GENE INDUCED TRANSGENIC TOMATO BY THE UMU-TEST

We examined the mutagenicity of extracts (juice and ethanol extract) f rom a transgenic tomato that was established by transfection of a gene encoding the coat protein of tobacco mosaic virus (TMV) to the F1 hyb rid between Lycopersicon esculentum LA1000 and L. peruvianum PI128650, by the umu-test with Salmonella typhimurium TA1535/pSK1002 as the tes t organism. The extracts showed no detectable mutagenicity. The extrac ts from the above-mentioned F1 hybrids and wild tomatoes and cultivars (L. peruvianum PI128650, L. peruvianum PI126944, L. pimpinellifolium LS1524, L. pimpinellifolium LA722, L. hirsutum LS503, Mini-carol, Sun- cherry, Momotaro, Odoriko, Kagome77, and Ponderosa) also showed no det ectable mutagenicity.
