Effect of Gene copy numbers of defense responses on seedling
survival
The optimal model at species level showed that only gene copy number of
defense response to insect influenced seedling survival rate with a
negative effect (r =-0.28, P =0.002, Fig. 3A). The seedling
survival rate at community level was best described by the model
including gene copy number of defense response to fungus, insect and
virus. The gene copy numbers of the defense response to fungus, insect
and virus have significantly negative effects (fungus:r∂ =-0.07, P =0.021; insect:r∂ =-0.11, P <0.001; virus:r∂ =-0.08, P =0.010) on seedling survival
rate (Fig. 3B).
