  1. Expression Angler [41] was used to find co-expressed genes in the AtGenExpress Plus Extended Tissue Set microarray data. The R-value represents the Pearson correlation coefficient of co-expression, set to a threshold of R > 0.90. Co-expressed genes that were also differentially expressed in the SND2∩Ko subset of SND2 overexpression data (Table 1) are indicated in the far right column.
