Table III. Transcriptional response of promoters containing Elements A, B, and B′ to UV-B, HL, and cold

Average and sd of transcriptional response to UV-B (Kilian et al., 2007), HL (Yamamoto et al., 2004), and cold (Lee et al., 2005) identified by microarray analysis are shown as log2(FC). The number of genes containing Elements A, B, and B′ in the promoter region are 236, 71, and 419, respectively. The number of genes analyzed is less because expression levels of some genes were below detectable levels. The value in parenthesis is retransformed from log2(FC) to the decimal expression of the FC. Rows indicated as FC > 2 show the percentage of genes responding to a stress treatment with an increase of more than 2-fold. *, Statistical significance (P < 0.05) over global percentage, judged by Fisher’s Exact Test.
