The traits elf18^<i>DC</i>- and elf18^<i>Ps</i>-induced SGI map a significant number of <i>a priori</i> 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.我们构建了包含77个基因的列表，这些基因已有公开研究证据表明，其可在响应elf18或flg22时改变SGI。其中“频率（frequency）”这一指标，指的是各性状所有关联峰对应的全基因组关联分析（Genome-Wide Association, GWA）候选基因的数量（即基因数，缩写为nb. genes）中，被检出的先验候选基因（a priori candidate genes）的数量。经验p值（empirical p-value）通过以下方式生成：沿基因组位置对各关联峰进行随机偏移，随后计算这些偏移后的峰所覆盖的基因集合中，检出的先验候选基因的频率。该基因组位置上的随机偏移过程会保留连锁不平衡（linkage disequilibrium）的模式，且该流程被重复执行100次。
