Gene Expression Preferences in Three Development Zones across Six Angiosperm Species.

(A) Ratio of genes expressed (average FPKM ≥ 0.5, at least two replicates have expression) in the root development zones across species. At, Arabidopsis; Cs, cucumber; Gm, soybean; Os, rice; Sl, tomato; Zm, maize; M, meristematic; E, elongation; D, differentiation.

(B) Merged PCA of gene expression in the root development zones from six angiosperm species samples. PCA was performed on all individual biological replicates from the same species and then plotted to the same figure.
