Contents
Annotated Information
Gene Symbol
- Os02g0738400 <=> OsHk6,Hk6',OHK5,HISTIDINE KINASE 5
Function
- OsHk6 was highly sensitive to isopentenyladenine (iP) and was capable of restoring cytokinin-dependent ARR6 reporter expression in the ahk2 ahk3 Arabidopsis mutant upon treatment with 1 nM iP.
- OsHk4 and OsHk6 mediated the canonical two-component signaling cascade of Arabidopsis to induce phosphorylation of ARR2.
- Ectopic expression of OsHk6 in rice calli promoted green pigmentation and subsequent shoot induc- tion, further supporting an OsHk6 in planta function as a cytokinin receptor.
- The action mechanism of OsHks is evolutionarily diverged from bacterial histidine kinases.
- OsHks are homomeric cytokinin receptors with distinctive cytokinin preferences in rice.
Expression
- OsHk4 and OsHk6 were highly expressed in spike- lets, suggesting that tZ and iP might play key roles in grain development.
You can also add sub-section(s) at will.
