  1. *Increase in N uptake efficiency is calculated from the difference between the value of the N content of transgenic event and control (wild-type) divided by the value of N content of control line multiplied by 100%
  2. **Increased in the grain yield is calculated from the difference between the results of grain yield/plant of transgenic lines to control (wild-type) divided by grain yield/plant of control line multiplied by 100%
