malfunction | the increase in the levels of 1D-myo-inositol 1,4,5-trisphosphate/Ca2+ caused by deficiency of inositol polyphosphate 5-phosphatases is sufficient to break pollen dormancy and to trigger early germination | Arabidopsis thaliana |
physiological function | the enzyme is crucial for maintaining pollen dormancy | Arabidopsis thaliana |
