6. Supplemental Figure S1. Phylogenic Relationship of Rice AP2 Family. A phylogenic dendrogram was derived from an alignment of the deduced amino acid sequences of 90 rice A P2 factors using the CLUSTAL W program. Of 139 AP2 factors predicted from the rice genome, we selecte d 90 that have EST information from NCBI database search using the tBLAST N program. Forty two stress-i nducible factors were indicated by boxes. Our subgroups I to VI shown in Table I are marked by circles.

Up-Regulation of Five Target Genes in OsCc1:AP37 and OsCc1:A P59 Plants in Comparison to Nontransgenic Controls. Homozygous T 4 lines of OsCc1:AP37, OsCc1:AP59, and nontransgenic (NT) control rice plants were grown in a greenhouse for 14 d. Transgenic and NT plants were then treated with various stress conditions as described in th e legends of Fig. 2. Transcript levels of five target genes listed in Supplemental Table S1 onli ne were determined by qRT-PCR (using primers listed in Supplemental Table S3 online).
