Fig. 4
Shoot biomass parameters of wild type and ljnpf2.9–1 mutants grown on different KNO3 conditions. a and b shoots length at 2 and 3 weeks after sowing; c and d fresh shoots weight at 2 and 3 weeks after sowing. Plant genotypes and KNO3 concentrations are indicated. Data bars represent the mean and standard errors obtained from 3 independent experiments (10 plants per experiment). Asterisks indicate significant differences with wild type values: *p < 0.02; ** < 0.0007
