Publication
Genbank accession number
Key message
- OsWRKY21 and OsWRKY108 interact within the nucleus and both bind to the W-box in the OsPHT1;1 promoter
- OsWRKY21 and OsWRKY108 function redundantly to promote phosphate accumulation through maintaining the constitutive expression of OsPHT1;1 under phosphate-replete conditions
- Overexpression of OsWRKY21 or OsWRKY108 led to increased Pi accumulation, resulting from elevated expression of OsPHT1;1
- By contrast, oswrky21 oswrky108 double mutants showed decreased Pi accumulation and OsPHT1;1 expression in a Pi-dependent manner
- The peak QTN (C/T) was located in the first coding region of a group III WRKY transcription factor OsWRKY21 (LOC_Os01g60640)
- These data suggest the essential role of OsWRKY21 in regulation of internode elongation and plant height in rice
- Most notably, overexpressing OsWRKY21 resulted in the semi-dwarf phenotype, early heading date and short internodes compared to the wild type, while the knockout mutant plants by CRISPR/Cas9 technology yielded the opposite

- OsWRKY108, OsWRKY21, OsWRKY108 is an integrative regulator of phosphorus homeostasis and leaf inclination in rice., Overexpression of either OsWRKY108 or OsWRKY21 led to up-regulation of Pi transporter genes and thus enhanced Pi accumulation
- OsAP2-39, OsWRKY21, OsDREB2B, an AP2/ERF transcription factor, negatively regulates plant height by conferring GA metabolism in rice., In summary, our study suggests that OsDREB2B plays a negative role in rice growth and development by regulating GA metabolic gene expression, which is mediated by OsAP2-39 and OsWRKY21, thereby reducing GA content and rice plant height
- OsDREB2B, OsWRKY21, OsDREB2B, an AP2/ERF transcription factor, negatively regulates plant height by conferring GA metabolism in rice., The yeast two-hybrid assay and bimolecular fluorescence complementation assay showed that OsDREB2B interacted with OsWRKY21
