Correlation between genome size (pg/1C) and log₁₀-transformed number of genes in the NBS and RLK families (Supplementary Table S1)

Species analyzed	N	NBS		RLK
		Coefficient (r)	P-value	Coefficient (r)	P-value
Oryza	8	−0.851**	0.007	−0.859**	0.006
Glycine	10	−0.372	0.290	−0.260	0.468
Gossypium	26	0.198	0.333	Not studied
Oryza + Glycine	18	0.312	0.208	0.038	0.881
Oryza + Glycine + Gossipium	44	0.062	0.691	Not studied

The variation is significant in two-tailed test at **P ≤ 0.01.
