Proposed model of OsDREB2B regulatory mechanism in plant height reduction in rice. Colored spindles indicate different transcription factors, and colored circles indicate different repressors. Colored rectangles indicate the cis-element binding sequence. Colored arrows indicate that OsDREB2B/WRKY21 complex can bind directly to the cis-element (s) on the promoters of GA metabolic genes. The black arrows represent the activation effect, and the hammer lines indicate the inhibition effect. Curved arrows in the dark indicate the transcriptional expression of genes, and the thickness of the line represents the relative transcription level. Genes in red letters are based on experimental evidence, genes in black letters are based on bioinformatic prediction.
