 A total of 9 different cis-acting elements commonly existed in the promoters of OsHsfs. Seven of these cis-acting elements were related to stress responses. Two cis-acting elements with the highest frequency were G-box/Sp1 and abscisic acid (ABA) response element (ABRE). These two elements are involved in the light responsiveness and the ABA response, respectively . CCGTCC/CAT-box, LTR, and ARE/GC-motif are cis-acting elements related to meristem expression, low temperature response, and anaerobic induction. Compared with classes B and C OsHsf genes, class A genes contained more these two cis-elements, suggesting that class A genes may play different roles from classes B and C genes.In addition to these two elements, other cis-elements occurred at a similar frequency among the promoters of these three classes.

    Digital Northern analysis showed that OsHsfs were expressed constitutively. The expressions of these OsHsfs in response to heat stress and oxidative stress differed among the members of the gene family. Promoter analysis identified a number of stress-related cis-elements in the promoter regions of these OsHsfs. No significant correlation, however, was found between the heat-shock responses of genes and their cis-elements.
