Gene Symbol
- Os01g0197700 <=> Gn1a, OsCKX2, CKX2, ckx2, Gn1a/OsCKX2, Os CKX2, CKX2/Gn1a
Function
- Gn1a is a quantitative trait loci (QTLs) that increases grain productivity in rice.
- Gn1a, is a gene for cytokinin oxidase/ dehydrogenase (OsCKX2), an enzyme that degrades the phytohormone cytokinin.
Mutation
- Reduced expression of OsCKX2 causes cytokinin accumulation in inflorescence meristems and increases the number of reproductive organs, resulting in enhanced grain yield.
Expression
Evolution
You can also add sub-section(s) at will.
