  • a The division of ospC was according to the sliding-window plot of Figure 4.

  • b Both dS and dN are estimated using Nei and Gojobori's method (Nei and Gojobori 1986) and their respective standard errors (SEs) are estimated using Nei and Jin's method (Nei and Jin 1989). Both of these methods are implemented in MEGA (Kumar et al. 1993).
