The rice Os03g0810100 was reported as OsIPT4 in 2006 [1] by researchers from Japan.
Contents
Annotated Information
Gene Symbol
- Os03g0810100 <=> OsIPT4,IPT4
Function
- Some phytohormones such as gibberellins (GAs) and cytokinins (CKs) are potential targets of the KNOTTED1-like homeobox (KNOX) protein.
- The rice (Oryza sativa) genes for adenosine phosphate isopentenyltransferase (IPT), can catalyze the rate-limiting step of CK biosynthesis.
- KNOX protein simultaneously decreases GA biosynthesis and increases de novo CK biosynthesis through the induction of OsIPT2 and OsIPT3 expression, and the resulting high-CK and low-GA condition is required for formation and maintenance of the meristem.
Phenotypic analysis
- Phenotypes of OsIPT overexpressers resembled those of KNOX-overproducing transgenic rice, although OsIPT overexpressers did not form roots or ectopic meristems, both of which are observed in KNOX overproducers.
You can also add sub-section(s) at will.
