The plot illustrates the principal components of (a) all 24 sample groups for 10,327 genes in “all”, (b) all 16 sample groups for 9,633 genes in “base and middle” and (c) all 8 sample groups for 6,555 genes in “needles” that were differentially expressed among time points. Abbreviations for time points are as described in the MethodsBack to article page
