The traits elf18DC- and elf18Ps-induced SGI map a significant number of a priori candidate genes.

We assembled a list of 77 genes that have published evidence to alter SGI in response to either elf18 or flg22. The measure ‘frequency’ indicates how many a priori candidate genes were found among the number of GWA candidate genes (nb. genes) for all peaks of each trait. The empirical p-value is generated by shifting the number of peaks along the genetic positions and calculating the frequency of found a priori genes in the number of genes under these shifted peaks. The random shift along the genetic position maintains patterns of linkage disequilibrium and was repeated 100 times.
