Rice successfully germinates under O2-deficient conditions utilizing fermentation-produced ATP. OsHXK7, a cytosolic hexokinase, is upregulated in germinating seedlings under O2-deficient conditions. We found that overexpressing O2HXK7 promotes germination and its null mutations suppress germination under O2-deficient conditions. This suggests that OsHXK7 is necessary for efficient seed germination under O2-deficient conditions.
