Other claims from this paper (15)
- Observation Young mature maize leaves had little nitrate reserve despite saturating N.
- Intervention effect Drought reduced CO2 assimilation after three days.
- Intervention effect Starch, glucose, and fructose accumulated in droughted leaves.
- Intervention effect Amino acids accumulated in droughted leaves.
- Intervention effect Sucrose did not accumulate in droughted leaves.
- Intervention effect Water deficit slightly increased extractable PEP carboxylase activity.
- Intervention effect Water deficit decreased PEP carboxylase sensitivity to malate.
- Intervention effect Water stress decreased sucrose phosphate synthase activity.
- Intervention effect Water stress increased sucrose phosphate synthase sensitivity to orthophosphate.
- Association Maximum nitrate reductase activity correlated with CO2 assimilation.
- Intervention effect Drought rapidly reduced nitrate reductase activation state and activity.
- Intervention effect Photosynthesis and nitrate reductase activity recovered upon nutrient restoration.
- Association Nitrate reductase transcripts declined with extractable activity.
- Observation Sucrose phosphate synthase and PEP carboxylase mRNAs were much less affected.
- Mechanism The authors infer coordinated N and C metabolism during drought through synthase and NR activities.
