t0“Rice alcohol dehydrogenase 1 promotes survival and has a major impact on carbohydrate metabolism in the embryo and endosperm when seeds are germinated in partially oxygenated water”
e3“The rad mutant endosperm had lower amounts of the α-amylases RAMY1A and RAMY3D, resulting in less starch degradation and lower glucose concentrations”

Other claims from this paper (7)
- Association In the rad mutant embryo the rate of ethanol fermentation was halved.
- Association Lactate concentrations in the mutant embryo were higher than in the wild type, at 2.4-fold.
- Association Alanine concentrations in the mutant embryo were higher than in the wild type, at 5.7-fold.
- Association Glucose and fructose concentrations in the embryo increased with time in the wild type but not in the rad mutant.
- Association The rad mutant endosperm had lower amounts of the alpha-amylases RAMY1A and RAMY3D.
- Association The rad mutant endosperm had lower glucose concentrations.
- Mechanism ADH1 is essential for sugar metabolism via glycolysis to ethanol fermentation in both embryo and endosperm.
