7.3.2.4 additional information a single nucleotide polymorphism leads to an H433R substitution in subspecies indica. The indica type shows a significantly stronger nitrate uptake ability than the japonica type. Transgenic japonica lines harboring the indica allele translocate more nitrate to shoots and generally grow better than the japonica wild-type Oryza sativa Japonica Group

General Information

EC Number General Information Comment Organism
7.3.2.4 physiological function nitrate allocation mediated by NPF7.9 is essential for balancing rice growth and stress tolerance. Nitrate allocation from roots to shoots is decreased in Npf7.9 mutants. Biomass, grain yield, and nitrogen use efficiency decrease in the mutant dependent on nitrate availability. In Npf7.9 mutants, less K accumulates in mutant shoots than in wild-type when supplied with 1 mM NH4NO3, but not with 0.25 mM NH4NO3 Oryza sativa Japonica Group
