The variation rate in different areas of CsuPLE1.1

Area	Length (average ± SEM)	No. of position variances* (average ± SEM)	Variation rate* (average ± SEM)
5′ outside the ORF region	613.2 ± 0.3	3.8 ± 0.4	0.0062 ± 0.0007 B
Inside the ORF region	1518 ± 0	8 ± 0.8	0.0053 ± 0.0005 B
3′ outside the ORF region	278 ± 0.1	3.1 ± 0.3	0.0113 ± 0.0011 A

*A certain position contains an/a insertion, deletion, transition or transversion was recorded as one variance position. For the variation rate, were significant variations (p < 0.01) between the 3′ outside the ORF region and inside the ORF region, and the 5′ outside the ORF region.
