Results of general linear modeling of lesion area for 12 tomato accessions by 95 B. cinerea isolates is shown (R lme4 package version 1.1-18-1; Bates et al., 2015). Two of the 97 isolates did not have replication across 2 experiments; therefore, they were dropped at this stage of analysis. The terms are as follows: Isolate is the 95 B. cinerea isolates; Domestication is wild tomato, S. pimpinellifolium, versus domesticated tomato, S. lycopersicum; Plant is 12 tomato genotypes nested within their respective domestication groupings. The experiment tests the random effect of 2 independent replicate experiments. The nested random effects of whole plant sampled, leaf sampled, and leaflet pair are included. In addition, interactions of these factors were tested (:). The degrees of freedom and p-value are shown. For fixed effects, the type II sum of squares and F-value are shown, and for random effects, the likelihood ratio test statistic is shown. P values in bold represent those crossing the significance threshold. Blank spaces within the table represent model terms for which that variance descriptor was not calculable due to it being a fixed or random effect.
