General Information

EC Number General Information Comment Organism
6.3.1.2 malfunction OsGS1;2 homozygously inserted mutants show severe reduction in active tiller number and hence panicle number at harvest. The mutants show marked reductions in contents of glutamine, glutamate, asparagine and aspartate, but an increase in free ammonium ions compared to the wild-type Oryza sativa Japonica Group
6.3.1.2 physiological function isozyme OsGS1;1 in the roots is unable to compensate for isozyme OsGS1;2 functions Oryza sativa Japonica Group
6.3.1.2 physiological function isozyme OsGS1;2 is important in the primary assimilation of ammonium ions taken up by rice roots. Isozyme OsGS1;1 is unable to compensate for isozyme OsGS1;2 functions in roots Oryza sativa Japonica Group
