Is positive Darwinian selection a driving force for the diversification of terpenoid biosynthesis in the genus Oryza?
In this study, we found that positive Darwinian selection is a driving force for the functional divergence of OryzaTPS1. This finding suggests that the diverged sesquiterpene blend produced by the Oryza species containing DAS may be adaptive, likely in the attraction of the natural enemies of insect herbivores.
Examiners show no general tendency to 'favour their own kind'. With confounding between variables, as far as the impact on candidates' case scores, substantial effects relate to candidate and not examiner characteristics. Candidate-examiner interaction effects were inconsistent in their direction and slight in their calculated impact.
