Feature detection by Linear Discriminant Analysis (LDA).

a,b The suitability of features to differentiate Bgh inoculated susceptible wild type (WT) barley, papilla resistant (mlo3) and hypersensitive resistant (Mla1) barley were tested using a LDA on hyperspectral signatures, gene expression profiles and the combined data sets 0–72 hai. c, Combining both data sets increased the separation between the different interaction types WT, mlo3 and Mla1. (Arrows indicate the changed centre of gravity per barley-Bgh interaction over the experimental period).
