THE DISTRIBUTION BETWEEN CELL NUCLEI OF ISOLOCUS BREAKS AND CHROMATID INTERCHANGES INDUCED BY RADIOMIMETIC CHEMICALS IN VICIA FABA

· Hereditas (Sweden)
Lateral root-tips of Vicia faba were treated with the radiomimetic agents 8-ethoxycaffeine (EOC), N-methylphenylnitrosamine (MPNA), and N-nitroso-N- methylurethan (NMU). The distribution between nuclei of the induced isolocus breaks and chromatid interchanges was determined and compared with the expected distribution, assuming a Poisson distribution. In all three cases, the distribution of both isolocus breaks and chromatid interchanges did not fit the Poisson distribution, there being an excess of cells containing two or more aberrations and a deficiency of cells having one aberration. The deviation from the expected Poisson distribution was particularly pronounced in the cases of interchanges induced by EOC and MPNA. The results are discussed. (auth)
