| 1.17.4.1 | additional information | construction of transgenic plants using Agrobacterium tumefaciens-mediated transformation. Complementation by gene construct introduction into calli generated from the mature embryos of v3 and st1 mutant kernels, respectively. The stripe1 mutant in Oryza sativa produces chlorotic leaves in a growth stage-dependent manner under field conditions. It is a temperature-conditional mutants that produces bleached leaves at a constant 20°C or 30°C, but almost green leaves under diurnal 30°C/20°C conditions, phenotype, overview. Expression profiles of genes associated with chloroplast development in mutant plants | Oryza sativa |

General Information
| EC Number | General Information | Comment | Organism |
|---|---|---|---|
| 1.17.4.1 | malfunction | wild-type plants exposed to a low concentration of an RNR inhibitor, hydroxyurea, produce chlorotic leaves without growth retardation, reminiscent of v3 and st1 mutants. Upon insufficient activity of RNR, plastid DNA synthesis is preferentially arrested to allow nuclear genome replication in developing leaves, leading to continuous plant growth | Oryza sativa |
| 1.17.4.1 | physiological function | RNR regulates the rate of deoxyribonucleotide production for DNA synthesis and repair. Rice virescent3 and stripe1 encoding the large and small subunits of ribonucleotide reductase are required for chloroplast biogenesis during early leaf development | Oryza sativa |
