Figure 9. The WRKY‐OBE complex represses the expression of stress‐responsive genes to coordinate plant growth and drought tolerance.

Figure 9

Under normal growth conditions, the group IId WRKY genes are well expressed, and the WRKY‐OBE complexes repress the transcription of stress‐responsive genes in order to prevent the inhibitory effect of the stress‐responsive genes on growth. Under drought stress conditions, the transcription of stress‐responsive genes is initially induced by stress‐activated transcription factors, and subsequently, the expression of group IId WRKY genes is repressed to further release the transcription of stress‐responsive genes, thereby enhancing the drought stress tolerance. The boxes A, W, and D shown in the promoter regions represent ABA‐responsive elements (ABREs), WRKY‐binding elements, and dehydration‐responsive elements (DREs), respectively.
