From: The auxin signaling pathway contributes to phosphorus-mediated zinc homeostasis in maize
ZmmiR167 is involved in P-mediated Zn homeostasis in maize. Inbred line B73 were grown in a hydroponic solution containing different combinations of P and Zn for 7 days. A Regulation of ZmmiR167 by P and Zn supply. miR399 or U6 RNA was probed as a loading control. B Overexpression of ZmmiR167b in transgenic maize. RNA gel blot analysis of ZmmiR167 levels in the wild type (WT) and two representative transgenic lines. U6 RNA was used as a loading control. Numbers below each lane indicate relative expression. C Total root length and density of 1° LRs of WT and ZmMIR167b transgenic maize as affected by P and Zn supply. Values are means ± SD (n = 12). D P and Zn concentrations of WT and ZmMIR167b transgenic maize as affected by P and Zn supply. Values are means ± SD (n = 4). Means with the same letter are not significantly different at P < 0.05 according to the LSD test
