Phenotypic analysis of the wild type (WT), vector control (VC), OsTCTP-OX and OsTCTP-RNAi transgenic rice plants. (A) Hg tolerance of WT (cv. Nipponbare), VC (vector control), OsTCTP-RNAi (#10 and #17) and OsTCTP-OX (#12 and #14). Germinated seeds were exposed to 0.5 mM CaCl2 solution (pH 5.5) containing 0 or 0.2 μM HgCl2 for 7 days. Scale bar = 2 cm. (B) Root length of WT (cv. Nipponbare), VC (vector control), OsTCTP-RNAi (#10 and #17) and OsTCTP-OX (#12 and #14). Root length was measured before and after the treatment. (C) The inhibition rate was defined as [1 – (the ratio of the root elongated of the plants receiving Hg treatment to that of the no-Hg control) × 100%]. For (B) and (C), data are given as means ± SD (n = 10). Means with different letters are significantly different (P < 0.05, Tukey’s test).
