Abstract
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.
