Abstract:
Nitrobenzene is an intermediate in the synthesis of aniline,benzidine and dinitrobenzene,and it is also a component in a number of commercial products.Nitrobenzene has been shown to induce cancers in many tissues of animals.In order to study the mutant effect of soybean root tip cells induced by Nitrobenzene,the abnormity was observed through plant cell micronucleus assay and chromosomal aberration test assay.The result showed that Nitrobenzene induced various types of chromosome aberration on soybean root tips,such as micronuclear and binuclear in interphase;chromosome fragments in metaphase;chromosome bridges and laggard chromosomes in anaphase.The mechanism of chromosomal aberration is probable that Nitrobenzene arise DNA breakage directly or excite free radical reaction in cells indirectly.
