Effects of heavy metal toxicities on root growth in rice seedlings overexpressing HsCIPKs. a-c Construct for HsCIPK overexpression (a), callus induction in rice mature embryos (b), and transgenic plants (c). d-h Root relative elongation rates (%; RER) of four-day-old rice seedlings overexpressing HsCIPKs treated for 24 h with 0.5 μM HgCl2 (d), 5 μM CdCl2 (e), 5 μM K2Cr2O7 (f), 0.25 μM CuSO4 (g), and 5 μM PbCl2 (h), respectively. Values shown are means ± SD. Single, double, and triple asterisks indicate P < 0.05, 0.01, and 0.001, respectively (t test; compared to the wild-type control NT seedlings). NT, nontransgenic regeneration lines
