Figure 3From: 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 LC-QTOF-MS metabolite profiling data from 4× and 2× leaves. First two components could explain 49.3% of metabolite variance. Component 1 explained 32.8% of the variance and component 2 explained 16.5%.Back to article page
