Comparison of Arabidopsis and rice supergene expression from common families. The distribution of GreenPhyl-defined gene families is based on combined transcript levels (FPKM, log₂ scaled) for all Arabidopsis genes (from FACS-purified AtCOBL9::GFP) and for all rice genes (from FACS-purified OsEXPA30::GFP) from each of the 7,291 families that possess at least one Arabidopsis gene and one rice gene. Pearson’s correlation coefficient is r = 0.77 for the total 7,291 families. Least-square fitted lines were generated for the 304 AtRHM families containing one or more OsRH gene (red dots, green line; adjusted r² = 0.39) and the 4,422 AtRH(-RHM) families containing one or more OsRH gene (black dots, orange line; adjusted r² = 0.51).
