The two compartments contained either 1.5 mM glutamine or 3 mM NO<sub>3</sub><sup>−</sup> as N sources. For each plate, one of the N sources (either glutamine or NO<sub>3</sub><sup>−</sup>) was <sup>15</sup>N-labelled. Bars indicate the fraction of N derived from each source for the shoot and for roots growing in the NO<sub>3</sub><sup>−</sup> compartment and the glutamine compartment. Bars represent average ± SE, n = 5. Different lower-case and capital letters indicate differences at p≤0.05 between plant parts, and between N sources, respectively.</p> 2013-02-20 19:00:13 plant biology ecology Biochemistry
