Figure 3From: Ecological implications of single and mixed nitrogen nutrition in Arabidopsis thalianaRelationship between %15N and %13C captured by the plants for (A) glutamine uptake (from nitrate & glutamine treatment) and (B) asparagine uptake (from the nitrate & asparagine treatment). Plants from the glutamine & asparagine treatment were too small to analyze for both %15N and %13C.Back to article page
