Effects of oligo-DNA sequences on mitigation of copper toxicity in P. bursaria. (A) Five different sequences of DNA hexamers examined. DNA sequences in gray-colored letters indicate the presence of complementary strands. (B) Comparison of the action of 5 different DNA oligomers on mitigation of copper toxicity. (C) Effect of GC-rich double stranded oligo-DNA concentration on mitigation of copper toxicity. Bars, SD (n = 4). Conditions for assays are identical as described for Fig. 1, except addition of DNA oligomers.
