The rice gene Os06g0257450 was reported as st1 in 2009[1] by researchers from USA and Japan.
Contents
Annotated Information
Gene Symbol
- Os06g0257450 <=> st1(ws1), ws1, st1, RNRS1, rnrs1
Function
- V3 and St1, which encode the large and small subunits of ribonucleotide reductase (RNR), RNRL1, and RNRS1, respectively. RNR regulates the rate of deoxyribonucleotide production for DNA synthesis and repair.
- The researchers found that the chlorotic phenotypes of v3 and st1 mutants are conditionally developed by missense mutations in the RNR subunits demonstrates that chloroplast biogenesis is arrested when plants fail to satisfy an increased requirement of RNR activity, particularly under restrictive temperatures or during the most active growth period (tillering stage).
Mutation
- The virescent3 (v3) and stripe1 (st1) mutants in rice (Oryza sativa) produce chlorotic leaves in a growth stage-dependent manner under field conditions. They are temperature-conditional mutants that produce bleached leaves at a constant 20℃ or 30℃ but almost green leaves under diurnal 30℃/20℃ conditions.
Expression
Evolution
