Distributions of degree for the genes in WHNP and CASN. (A) The CASN and non-CASN genes in WHPN are on the x axis; (B) The seed genes, optimized genes and rest potential genes in CASN are on the x axis. The y axis represents the degrees for these nodes. For the box plot, the top bar (black) is the lowest point within the 1.5 interquartile from the lower quartile, and the bottom bar (black) is the highest point within the 1.5 interquartile of the upper quartile, the top of box (blue) is the upper or third quartile, the bottom of box (blue) is the lower or first quartile, the middle bar is the median value. Pluses (red) are possible outliers.
