From: Beyond nitrate transport: AtNRT2.4 responds to local and systemic nitrogen signaling in Arabidopsis

AtNRT2.4 participates in root system architecture and systemic nitrate signal transduction. a-c Root morphology, total root length, and lateral root number in homogeneous treatments (C.NaCl, C.NaNO3) and split-root system (Sp.NaCl/Sp.NaNO3). The diameter of the Petri dish amounts to 9 cm. The data represents mean ± SE (n = 4), and the letters above the horizontal lines are based on Tukey's HSD test (p < 0.05)
