“…An optimal adapting dose has also been found in clastogenic adaptation studies (reduction in yields of chromosomal aberrations after pretreatment with low mutagen doses) induced by certain chemical mutagens such as alkylating agents or maleic hydrazide in Viciafaba cells (Rieger et al 1984, Heindorff et al 1987b.…”

Prelreatment of Vicia faba root tip cells with low doses of 60Co T-radiation can reduce the yield ofmicronuclei induced by a subsequent high dose ofT-radiation (1.5 Gy). This adaptation to "/-radiation possesses the following characteristics: (1) this phenomenon can be induced by an optimal range of low doses of "/-radiation applied acutely or fractionally; (2) the expression of this response seems to be transitory and depends on the time interval between adapting and challenging doses of"/-radiation.

“…This suggests that at least part of the genetic variation in tissue culture is caused by stress and forms part of an adaptive strategy. To some extent in contradiction with this view, Heindorff et al (1987) reported that stress pre-treatment of Vida/aha root meristems renders these meristems less susceptible to mutagenic treatment.…”

The induction of chromosome aberrations in tobacco root tip cells was measured after exposure to either 18 MeV/n carbon ions or 2 MeV electrons. The RBE value for acute exposure was found to be about 10. Splitting the dose into two fractions did not produce any significant effect on the yield of aberrations following carbon-ion exposure, whereas a clear decrease was observed after exposure to electrons thereby indicating an induction/activation of error-free repair after the first fraction. Moreover, this decrease appeared to be independent of the types of chromosome aberrations. On the other hand, it was suggested that the lack of any significant effect on the yield of aberrations is either due to a lack of error-free repair or to a less efficient damage repair after exposure to carbon ions.
