Abstract excerpt
Transcription factors (TFs) play a critical role in regulating the expression of drought-responsive genes. Elucidating how TFs are modulated by stress signals will contribute to deciphering the impacts of drought on transcriptional regulation. We discovered that the mutation of an HD-Zip IV TF ZmOCL1 (OUTER CELL LAYER1) enhances susceptibility to water deficit. Transcriptome analysis and biochemical evidence...
