WRKY46, WRKY54, and WRKY 70 Play Negative Roles in Drought Response.

(A) Phenotypes of wild-type, wrky46, wrky54, wrky70, and w54t plants before drought (top), after drought (middle), and 2 d after rewatering (bottom).

(B) The survival rate after recovery was determined. The mean and sd were from three biological repeats.

(C) Venn diagram showing comparisons among genes differentially expressed in w54t and genes up- or downregulated by dehydration in the wild type.

(D) Clustering of dehydration downregulated genes in the wild type and w54t mutants under control conditions (W) or dehydration (D).

(E) Clustering of dehydration upregulated genes in the wild type and w54t mutants under control conditions (W) or dehydration (D). Values indicate normalized expression levels.
