The rice Os01g0177400 was reported as OsGA3ox2 in 2003 [1] by researchers from Japan.
Contents
Annotated Information
Gene Symbol
- Os01g0177400 <=> GA3OX2, GA3ox1, OsGA3ox2, d18,OsD18
Function
- OsGA3ox2 (D18) encodes GA 3-oxidase.
- OsGA3ox2 is important in controlling bioactive GA synthesis for shoot elongation but not for reproductive development.
Phenotypic analysis
The rice d18 mutant is a severe GA-deficient dwarf, but its flower and grain development are not affected。
Expression
- In wild-type rice, expression of OsGA3ox2 is regulated by the endogenous bioactive GA content.
- Indeed, the OsGA3ox2 transcript was upregulated by uniconazole (an inhibitor of GA biosynthesis) treatment and downregulated by bioactive GA 3 application —as was the transcript of the green revolution rice gene, OsGA20ox2 (SD1), which encodes GA 20-oxidase 9 (20ox2 in Fig. 2b).
You can also add sub-section(s) at will.
Knowledge Extension
- Dwarfing is one of the most valuable traits in crop breeding, because it results in plants that are more resistant to damage by wind and rain (lodging resistant) and have stable increased yields.
- Dwarf mutants have been extensively characterized in many plant species. The endogenous phytohormone GA is one of several factors associated with the dwarf phenotype.
