1.8.3.1 | malfunction | silencing of ZmSO could lead to seed germination delay upon sulfite exposure, but not under normal conditions | Zea mays |
1.8.3.1 | physiological function | sulfite oxidase plays an important role in sulfite metabolism by catalyzing the physiologically vital oxidation of sulfite to sulfate in plants. Sulfite oxidase is essential for timely germination of maize seeds upon sulfite exposure, seed germination is inhibited by sulfite. Embryonic sulfite oxidase might be essential for timely seed germination upon sulfite exposure in maize | Zea mays |
