Gene retention patterns among bamboo subgenomes relative to the rice genome. The significance of differences for interspecies comparisons (red) and intersubgenome comparisons (black) was determined by two-sided Wilcoxon rank-sum test (boxplots: centerline, median; box limits, first and third quartiles; whisker, 1.5x interquartile range; n is the number of sliding windows used in evaluating gene retention).
