Table 1.

Tests for over and under representation of differentially expressed genes in CNS with greater than (CNS Gain), less than (CNS Loss), or no change (No CNS Change) relative to Col-0. Numbers in parenthesis refer to the percent of the gene types (CNS Gain, CNS Loss, No CNS Change) which are up or down regulated.

Gene type	Average number of upregulated genes per accession (%)	Pvalue (hypergeometric test)	Average number of downregulated genes per accession(%)	Pvalue (hypergeometric test)
CNS gain	270.25 (6.30)	<1 × 10–10	112 (2.61)	<1 × 10–10
CNS loss	49.5 (1.86)	<1 × 10–10	203.25 (11.357)	<1 × 10–10
No CNS change	404.75 (2.212)	<1 × 10–10	631.5 (3.380)	<1 × 10–10
