From: Intergrative metabolomic and transcriptomic analyses unveil nutrient remobilization events in leaf senescence of tobacco

Figure 3

Principal component analysis (PCA) of metabolite profiles from (A) upper leaf, (B) middle leaf and (C) Lower leaf during tobacco leaf senescence. Each point represents an independent biological replicate. Red, blue, green, purple, orange, yellow, brown and pink colors represent samples at 15, 25, 35, 45, 55, 65, 75 and 85DAT, respectively. Triangle, box and dot denote metabolomes of UL, ML and LL, respectively. Plotting of the first and second component is shown. The circles indicate the 95% confident regions.
