Information
- Symbol: OsbZIP18
- MSU: LOC_Os02g10860
- RAPdb: Os02g0203000
Publication
- Natural variation in the OsbZIP18 promoter contributes to branched-chain amino acid levels in rice, 2020, Plant Physiol.
- OsbZIP18, a Positive Regulator of Serotonin Biosynthesis, Negatively Controls the UV-B Tolerance in Rice., 2022, Int J Mol Sci.
Genbank accession number
Key message
- We further demonstrated that OsbZIP18 is strongly induced by nitrogen (N) deficiency and that N starvation results in enhanced BCAA levels in an OsbZIP18-dependent manner
- Here, we identified the basic leucine zipper transcription factor OsbZIP18 as a positive regulator of serotonin biosynthesis in rice
- Overexpression of OsbZIP18 strongly induced the levels of serotonin and its early precursors (tryptophan and tryptamine), resulting in stunted growth and dark-brown phenotypes
