TABLE 3.

Rates of protein evolution (dN/dS) in gametophytic (GM) versus sporophytic (SP) or gametophytic + sporophytic (GM + SP) loci.

	dN/dS			Loci with dN/dS > 1
Group	N	Mean	SE	Median	Number	Proportion	p1
a) Gametophytic vs. sporophytic
Gametophytic only	86	0.3275	0.0576	0.24	3	0.0349	0.5574
Sporophytic only	2033	0.2958	0.0586	0.21	68	0.0334
b) Gametophytic vs. GM + SP
Gametophytic only	86	0.3275	0.0393	0.24	3	0.0349	0.2833
Gametophytic + sporophytic	15778	0.2685	0.0394	0.20	383	0.0243
c) Ovule loci
Ovule only	71	0.3418	0.0036	0.25	3	0.0423	0.8542
Ovule + sporophytic	7884	0.2874	0.0448	0.21	225	0.0285
d) Pollen loci
Pollen only	13	0.2521	0.0679	0.16	0	0.0000	0.8316
Pollen + sporophytic	277	0.2496	0.0695	0.18	4	0.0144

Within each GLM, tissue groups did not differ in mean dN/dS (Supplementary Table 9).
