List of the 25 most repressed genes after SA treatment, ranked by decreasing degree of repression

AGI, Arabidopsis Genome Initiative gene index; log2 I, log2 average signal intensity (6–7 corresponds to a low level of expression, 14–15 corresponds to a high level of expression); log2 ratio, log2 ISA − log2 Iwater. Bonferroni-corrected P values were 0.05 in all cases.
