Cloned(Commentary)

Cloned (Comment) Organism
gene Os03g0694900 encodes wild-type OsValRS, and gene LOC_Os07g06940 encodes enzyme mutant WP1, map-based cloning of the WP1 gene to the short arm of chromosome 7 between two simple sequence repeat markers, Bs8 and Bs1, DNA and amino acid sequence determination and analysis Oryza sativa Japonica Group

Protein Variants

Protein Variants Comment Organism
additional information a single base change in OsValRS2, changing a Trp into a Cys, causes virescent to albino mutant phenotypes in seedlings and white panicles at heading, the mutant is termed the white panicle 1 (wp1) mutant. The white panicle1 mutant form of a Val-tRNA synthetase (OsValRS2) from Oryza sativa is targeted to both chloroplasts and mitochondria. The wp1 mutants are defective in early chloroplast development, and wp1 is impaired in chloroplast ribosome biogenesis. Expression of nuclear-encoded photosynthetic genes is significantly repressed, while expression of many chloroplast-encoded genes also changed significantly in wp1 mutants, although mRNA levels of some genes are higher in wp1 than in wild-type. Phenotype, overview Oryza sativa Japonica Group
