Identification of Ψs in Seven Plant Species.

(A) Number of Ψs identified in each genome.

(B) Distribution of genes and the different types of Ψs across chromosomes (Chr) in P. trichocarpa, Arabidopsis, and B. distachyon.

(C) Comparison of evolution between pairs of FG–FG (functional WGDs) and Ψ–FP (closest FPs).

(D) Distribution of sequence similarity to their closest FPs (as a function of Ψ age) for P. trichocarpa. CDS, coding sequence.

(E) Comparative distribution of Ψs and paralogs per gene in P. trichocarpa.
