Annotated Information
Gene Symbol
- Os07g0169700 <=> OsGA20ox3
Function
- Gibberellin (GA) 20-oxidase (GA20ox) catalyses consecu- tive steps of oxidation in the late part of the GA biosynthetic pathway.
- OsGA20ox3 plays a positive role in plant stature of rice and suggest that OsGA20ox3 overexpression is likely the reason for the elongated phenotype of 17S-14 mutant plants.
- Increase OsGA20ox3 expression enhances rice susceptibility to pathogens.
- OsGA20ox3 plays an important role in regulating not only plant stature but also disease resistance in rice.
Expression
- RT-PCR analysis of the OsGA20ox3 transcript was performed using total RNA isolated from various organs of the WT and 17S-14 plants. OsGA20ox3 was broadly expressed in vegetative organs of 2-week-old seedlings, including leaves, sheaths, and roots.
- The OsGA20ox3 transcript was most abundant in the panicles and not detected in leaves, sheaths, culms, or roots at the heading stage of rice. In contrast, the OsGA20ox3 transcript accumulated at high levels in all organs examined in the 17S-14 plants.
Figure 1. Expression patterns of OsGA20ox3 in wild-type (WT) and 17S-14 mutant (MT) plants were examined by reverse-transcriptase polymerase chain reaction.[1].
