Table 2 Relationship between the expression level and the number of seed pairings in the distance range of 5 kb. Each dataset was divided into two groups according to the normalized average of the 10 kb window.
The normalized expression level is represented in the form of average ± standard error. Each number in the parentheses denotes the number of genes with a seed pairing. It should be noted that some genes have multiple seed pairings in its mRNA form and upstream or/and downstream regions.
