Genetical evaluation of black nightshade plant solanum

This was correlated with high increase in phage induction and percent of clear plaques. Transduction frequencies of streptomycin and tetracycline resistance genes were also affected. However, by using 10% of the plant (seed – shoot – root) extract with different concentrations of the powerful mutagenic agent (EMS), the extract showed a remarkable anti-mutagenic response against EMS in prophage induction and transducing ability.These results do agree with the cytological examination of Vicia faba L. root tips that treated with plant (seed – shoot – root)extract. The mitotic index has been reduced and many chromosomal abnormalities have been observed. The abnormalities included compact and non-compact nuclei, formation of binucleate and chromosomal aberrations such as fragments and bridges.
