Treatment of Vicia faba main root meristems with methyl iodide (MeI) 2 h before challenge treatment with triethylene melamine (TEM) significantly reduced the yield of metaphases with chromatid aberrations, i.e., resulted in clastogenic adaptation. Combined treatment with MeI and TEM increased the aberration yield; MeI treatment alone (10(-3) M, 0.5 h) was without clastogenic effect. No protective effects were observed after MeI pretreatment and challenge treatment by maleic hydrazide (MH). The data obtained in V. faba are compared to those previously reported for E. coli.

UI MeSH Term Description Entries
D007887 Fabaceae The large family of plants characterized by pods. Some are edible and some cause LATHYRISM or FAVISM and other forms of poisoning. Other species yield useful materials like gums from ACACIA and various LECTINS like PHYTOHEMAGGLUTININS from PHASEOLUS. Many of them harbor NITROGEN FIXATION bacteria on their roots. Many but not all species of "beans" belong to this family.
