Shoots weight/unit length of wild type and ljnpf2.9 mutants grown in the presence of different N sources. Plant genotypes and N sources concentrations are indicated. 0.5 mM ammonium succinate (NH4OOC(CH2)COONH4) is equivalent to 1 mM ammonium. Data bars represent the mean and standard errors obtained from 3 independent experiments (10 plants per experiment). Asterisks indicate significant difference with wild type values: *p < 0.0001; **p < 0.001; ***p < 0.002
