Fig. 8From: Auxin efflux carrier ZmPIN1a modulates auxin reallocation involved in nitrate-mediated root formationEffects of auxin transport inhibitor NPA on PR and LRP of ZmPIN1a-OE plants. A-C The inhibition rate of PR length (A), of LRP density (B), and LRP number (C) of ZmPIN1a-OE plants after NPA treatment under NN and LN conditions. Inhibition rate = [(NN + NPA)—NN] /NN, [(LN + NPA)—LN] /LN. Values with error bars represent mean ± SD (n = 8). Different letters indicated a significant difference between different treatments calculated by Fisher's LSD (P ≤ 0.05)Back to article page
