Predicted cis elements in the promoters of Arabidopsis hsp70 genes. Promoter sequences for 11 Arabidopsis hsp70 genes, a cold-inducible gene (Rd29A/Cor78), and a heat-inducible gene (Hsp17.4) were analyzed. The numbers at the bottom indicate the number of nucleotides upstream to the translation initiation codon, ATG. Induction fold of each gene in response to heat and cold are indicated as solid diamonds; one diamond, less than 5-fold; two diamonds, 5- to 10-fold; and three diamonds, more than 10-fold. ●, Perfect HSE (nTTCnnGAAnnTTCn or nGAAnnTTCnnGAAn). ○, Imperfect HSE. ▴, The core sequence of CRT/DRE (CCGAC). ▪, TATA box. Only a small portion (approximately 200 bp) of the promoter region for Hsp70 was available at the time of analysis.
