Table 1. Defense genes are associated with additive genetic variation.
The number of genes detected (of 11,042 genes compared; Supplementary Table 1) for each experiment, and proportion significant for GCA. The number of defense genes detected (of 658; supplementary Figure 1); and the number and percent of defense genes with GCA. A Chi-Square test of association between the detection of GCA and the designation of a gene as being involved in defense was performed. P values were calculated exactly (Edgington 1995).
