Other claims from this paper (13)
- Intervention effect Nitrate depletion from the medium was more intense under hypoxia than normoxia
- Intervention effect in the presence of chloramphenicol, consumption under hypoxia was significantly reduced
- Intervention effect this effect was partially eliminated by chloramphenicol
- Mechanism Nitrate consumption sensitive to chloramphenicol was attributed to bacterial activity.
- Intervention effect Endogenous root nitrate was strongly reduced under hypoxia indicating mobilization.
- Intervention effect the transport of nitrate to the shoot via the xylem was also reduced under hypoxia
- Association the severity of this reduction was dependent on the concentration of nitrate in the medium
- Observation at least some of the nitrate in the xylem came from the medium
- Intervention effect Root nitrate reductase was also strongly reduced under hypoxia
- Intervention effect Root nitrate reductase was also strongly reduced under hypoxia, but recovered rapidly on return to normoxia.
- Observation the reduction of some nitrate to nitrite (despite the reduced nitrate reductase activity) followed by its release to the medium (at least one-third of the nitrate consumed followed this route)
- Observation the transport of nitrate to the shoot
- Observation it is highly unlikely that these metabolic routes account for all the nitrate consumed.
