Table 2 The parameters and dates of the duplication evens in the paralogous PpNF-Ys.

The paralogous gene		KS	KA	Ka/Ks ratio	Date (million year ago)
PpNF-YA2	PpNF-YA6	0.66	0.55	0.83	22.00
PpNF-YB5	PpNF-YB6	1.08	0.21	0.19	36.00
PpNF-YB4	PpNF-YB8	2.05	0.43	0.21	68.33
PpNF-YB9	PpNF-YB11	0.4	0.55	1.38	13.33
PpNF-YB2	PpNF-YB10	0.62	0.28	0.45	20.67
PpNF-YC3	PpNF-YC5	1.79	0.22	0.12	59.67

Ks and Ka were calculated using the program DNASP 6.0 [34]. The date of the duplication events in the paralogous PpNF-Ys were analzyzed by the formula T = Ks/2λ, λ representing the estimated clock-like rates of synonymous substitution, which was 1.5 × 10⁻⁸ substitutions/synonymous site/year in dicots [4]
