Effects of Cd2+、Al3+ on the DNA synthesis and DNA repair in Vicia faba
Cd~(2+)、Al~(3+)对蚕豆(Vicia faba)DNA合成及修复的影响

With the method of incorporating 3H TdR into DNA in Vicia faba in vivo,the effects of different concentrations of metal ions(Cd 2+ and Al 3+ ) on the scheduled DNA synthesis and DNA repair (using the unscheduled DNA synthesis,UDS,as its endpoint) were studied.The results show as follows.The low concentrations of Cd 2+ and Al 3+ promoted the DNA synthesis and induced UDS in Vicia faba in vivo (Cd 2+ <20mg/l,Al 3+ <100mg/l).When the concentrations of Cd 2+ and Al 3...
