Discussion
To evaluate NDD mediated by multiple natural enemies, we evaluated the effects of functional CNVs of defense response extracted from transcriptome on seedling survival. The gene copy numbers of defense response to fungus, insect and virus are significantly and negatively associated with survival rates, which does not support the Hypothesis I. The Hypothesis II, that neighborhood functional CNV dissimilarity increase seedling survival, was verified in defense response to bacterium and virus, but we gain an opposite effect in defense response to insect. Below the specific results linked to each hypothesis are discussed.
