Other claims from this paper (11)
- Intervention effect Crops grew better with nitrate N than with ammonium N.
- Intervention effect Shoots of rice and wheat gained more fresh weight with ammonium N.
- Intervention effect Ammonium N increased PEP carboxylase activity of various crops by 8-61% in the leaf blade.
- Intervention effect Ammonium N increased PEP carboxylase activity in the root by as much as 4.5 folds.
- Intervention effect Ammonium-N at a very low concentration significantly enhanced root PEP carboxylase activity.
- Observation Optimal pH for rice root PEP carboxylase was between 8.0 and 8.5 in Tris-HCl or Hepes-KOH buffer.
- Observation PEP carboxylase from the roots of Tainung 67 rice showed no decrease in enzyme activity up to 7 hours after extraction.
- Observation The velocity versus PEP concentration response curve was hyperbolic at pH 8.0.
- Observation The velocity versus PEP concentration response curve was sigmoid at pH 7.0.
- Observation The Km for PEP of root PEP carboxylase was 0.16 mM at pH 8.0.
- Observation The ammonium-N responsive root PEP carboxylase was similar to leaf-blade PEP carboxylase of C3 plants in many aspects.
