TABLE 1.

Rates of protein evolution (dN/dS) in different broad classes of loci.

	Per locus dN/dS					Loci with dN/dS > 1
Class	N loci	Mean	SE	Median	Tukey test¹	Number	Proportion²	Fisher’s exact tests¹
General	16221	0.2709	0.0026	0.20	a	399	0.0246	a
Vegetative	923	0.2783	0.0111	0.19	ab	26	0.0282	ab
Reproductive	670	0.3071	0.0142	0.21	b	28	0.0418	b

dN/dS calculated for each locus using a one ratio test in PAML.

¹See Supplementary Table 4.

²The proportion of genes with dN/dS > 1 differed among classes of loci (X² = 7.9696, p = 0.0186).
