Nucleotide diversity (π) of NBS gene family in different pear groups
| Pear accessions—groups (number of samples) | π |
π (Coding region) |
|---|---|---|
| All (131) | 5.88E-03 | 4.75E-03 |
| Wild (61) | 5.92E-03 | 4.82E-03 |
| Cultivated (70) | 6.84E-03 | 5.46E-03 |
| Asian (71) | 6.02E-03 | 4.74E-03 |
| European (60) | 5.65E-03 | 4.76E-03 |
| Asian wild (34) | 6.47E-03 | 5.15E-03 |
| Asian cultivated (37) | 6.23E-03 | 4.88E-03 |
| European wild (27) | 5.91E-03 | 5.02E-03 |
| European cultivated (33) | 6.48E-03 | 5.40E-03 |
The nucleotide diversity was calculated by VCFtools with a 1000 bp sliding windows and step size of 500 bp. The sequence data of 131 pear accessions were obtained from previous study [3]
