Figure 2From: Comparative metabolic and transcriptional analysis of a doubled diploid and its diploid citrus rootstock (C. junos cv. Ziyang xiangcheng) suggests its potential value for stress resistance improvement Principal component analysis of GC-MS metabolite profiling data from 4× and 2× leaves. First two components could explain 75.8% of the metabolite variance. Component 1 explained 58.6% of the variance and component 2 explained 17.2%.Back to article page
