- Intervention effect Hypoxic pretreatment increased ATP in anaerobic root tips.
- Intervention effect Hypoxic pretreatment increased ATP/ADP and adenylate energy charge ratios.
- Intervention effect Hypoxic pretreatment raised anaerobic ethanol production.
- Association Acclimated root tips had increased ADH activity.
- Observation Hypoxic pretreatment induced ADH-2 isozymes.
- Observation Adh1 mutant roots lacked constitutive ADH.
- Observation Adh1 mutant roots produced ethanol slowly under anoxia.
- Observation Hypoxically pretreated mutant roots induced ADH2.
- Intervention effect Hypoxically pretreated mutant roots had higher energy metabolism.
- Intervention effect Hypoxically pretreated mutants produced ethanol at a rate comparable to nonmutants.
- Observation Responses were insensitive to nitrate presence.
- Observation Ethanol production rate was about 50 times nitrate reduction rate.
- Observation Unacclimated root tips appeared not to survive beyond 8 to 9 hours of anoxia.
- Intervention effect Hypoxically pretreated root tips tolerated more than 22 hours of anoxia.
