Fig. 1From: Tobacco plants expressing the maize nitrate transporter ZmNrt2.1 exhibit altered responses of growth and gene expression to nitrate and calciumGrowth of 7 days-seedlings under 1 mM nitrate (A, C) or 10 mM nitrate (B, D) and various Ca2+ and K+ concentrations for 14 days. Primary root length (A, B) and fresh biomass (C, D) of six to ten plants were measured. Wt: wild type, ZmN6: transgenic plant expressing ZmNrt2.1. Error bars indicate the standard deviation. Different letters indicate significant differences (P < 0.05) between plants-treatments of each panel, whereas no letter or same letters indicate insignificant differencesBack to article page
