From: Dynamic differential evolution schemes of WRKY transcription factors in domesticated and wild rice

WRKY groups are consistent across Oryza but are not equally found across chromosomes. Stacked columns represent the number of WRKY genes identified under the WRKY group classification for each of the 12 chromosomes in Oryza. Different colors represent different Oryza species. Species are arranged based on divergence from the Oryza ancestor, from oldest to youngest.
