Information
- Symbol: OsGASD
- MSU: LOC_Os04g43290
- RAPdb: Os04g0512300
Publication
- Gibberellic acid sensitive dwarf encodes an ARPC2 subunit that mediates gibberellic acid biosynthesis, effects to grain yield in rice., 2022, Front Plant Sci.
Genbank accession number
Key message
- The osgasd knockout (Ko) mutation reduced GA3 content in shoots as well as plant growth and height
- These observations suggest that OsGASD is involved in maintaining GA homeostasis to regulate plant development, thereby affecting rice growth and productivity
- Transcriptome analysis of flag leaves of OsGASD Ox and osgasd Ko plants revealed that OsGASD regulates cell development and the expression of elongation-related genes
- Rice plants overexpressing OsGASD (Ox) showed increased plant height and grain yield compared to the WT
- However, GA application restored the plant height of the osgasd Ko mutant to a height similar to that of the wild type (WT)
