a VIP means variable importance in the projection values from partial least squares discriminant analysis (PLS-DA)
bp(corr) indicates loadings scaled as a correlation coefficient (ranging from −1.0 to 1.0)
cC/G means the ratio of the mean peak intensity in chlorotic (C, full sun light) and green (G, shaded) tea plants
