Figure 4From: A rapid, simple method for the genetic discrimination of intact Arabidopsis thaliana mutant seeds using metabolic profiling by direct analysis in real-time mass spectrometryPartial least square-discriminant analysis (PLS-DA) plot of direct analysis in real-time mass spectrometry (DART-MS) spectral data from intact seeds of 14 Arabidopsis mutant lines. Symbols represent each ecotype and mutant line. Dotted lines represent Col-0 (black dot circle) and Ler (blue dot circle) backgrounds.Back to article page
