Figure 1From: Global transcription profiling reveals differential responses to chronic nitrogen stress and putative nitrogen regulatory components in ArabidopsisThree-week-old wild type Arabidopsis plants under different N conditions. A: Shoot biomass. Average of shoot biomass (mg/plant) of 6 to 8 three-week-old wild type Arabidopsis plants under the N-sufficient (3 mM), mild (1 mM) and severe (0.3 mM) N-limiting conditions are presented, as well as sd. B: Nitrate levels: Average of nitrate levels (mg/g fresh weight) of 3 biological samples under different N conditions (each sample from a pool of 3 plants) are presented, as well as sd.Back to article page
