Table 2. Estimated time of transposition of NBS-R genes.

Single NBS-R genes	Ancestor NBS-R gene	Helitron footprints	Ks	Mya
R125 (Vc)	CL46_314 (Va)	+	1.34	67
R132 (Vc)	CL46_314 (Va)	+	1.23	62
R255 (Vc)	CL46_314 (Va)	+	0.69	35
R129 (Vc)	CL32_208 (Va)	+	0.94	47
R346 (Vc)	CL35_237 (Va)	+	1.89	95
R256 (Vc)	CL4_22 (Va)	+	1.23	62
R39 (Va)	CL19_113 (Vc)	+	0.77	39
R29 (Va)	CL19_113 (Vc)	+	0.52	26

Ks values of two genes were used to infer time following Schranz and Mitchell-Olds [3].

Va and Vc are putative component genomes of grapevine.
