We examined the mutagenicity of the extract of transgenic tomato by Am
es test, to assess the safety of a transgenic tomato that had been est
ablished by gene transfection of a gene coding the coat protein of TMV
. Juice and ethanol extract prepared from transgenic tomato showed no
detectable mutagenicity on Salmonella typhimurium TA98 and TA100 with
or without S-9 mix. Furthermore, extracts from six kinds of commercial
tomato also did not show any mutagenicity.
