Selective pressure on non-TIR-NBS-encoding genes in Chinese chestnut.
Numbers represent the dN/dS ratio for each gene family using the branch model; 2∆ln represents the result of the LR test for the site model; * and ** represent, respectively, significant (2∆ln > 5.991, p < 0.05) and highly significant (2∆ln > 9.210, p < 0.01) tests for positive selection between model M7 and M8.
