- Information
- Symbol: OsGA2ox6
- MSU: LOC_Os04g44150
- RAPdb: Os04g0522500
- Publication
- Activation of gibberellin 2-oxidase 6 decreases active gibberellin levels and creates a dominant semi-dwarf phenotype in rice Oryza sativa L., 2010, Journal of Genetics and Genomics.
- A novel class of gibberellin 2-oxidases control semidwarfism, tillering, and root development in rice, 2008, Plant Cell.
- Genbank accession number
- Key message
- BLASTP analysis revealed that OsGA2ox6 belongs to the class III of GA 2-oxidases, which is a novel type of GA2ox that uses C20-GAs (GA(12) and/or GA(53)) as the substrates
- Interestingly, we found that a GA biosynthesis inhibitor, paclobutrazol, positively regulated the OsGA2ox6 gene
- These results indicate that OsGA2ox6 mainly affects plant stature, and the dominant dwarf trait of the H032 mutant can be used as an efficient dwarf resource in rice breeding
- RNAi and ectopic expression analysis of OsGA2ox6 indicated that the dwarf trait and the decreased levels of bioactive GAs in the H032 mutant were a result of the up-regulation of the OsGA2ox6 gene
