Fig. 5. Venn diagram representing the distribution of drought, high-salinity, and heat-shock (HS)-responsive DREB2A up-regulated genes. The numbers in parentheses indicate total numbers of genes that showed >2 expression ratios in the microarray analysis of 35S:DREB2A CA plants and total numbers of DREB2A up-regulated genes that showed >2 expression ratios in the microarray analysis of drought, high-salinity (NaCl), and HS stress response. The numbers that are not denoted by parentheses indicate the number of genes in each group (K.M. and K.Y.-S., unpublished data) were used for analysis of drought and high-salinity response.





Fig. 6. Expression analysis of DREB2A and DREB2A up-regulated genes in the 35S:DREB2A CA plants. Total RNA was prepared from 3-wk-old Arabidopsis plants from two and one independent lines of transgenic plants harboring 35S:DREB2A CA and the vector (wt), respectively. The relative mRNA amount of DREB2A and DREB2A up-regulated genes was analyzed by quantitative RT-PCR (the highest expression level was set to 100). Data represent the means and standard errors of three replications.
