Other claims from this paper (18)
- Intervention effect One group of carbon compounds supported about as much root elongation as sucrose.
- Intervention effect A second compound group supported elongation comparable to no sugar.
- Intervention effect A third compound group reduced or eliminated root growth.
- Intervention effect No tested compound notably changed root diameter.
- Association Root diameter correlated weakly and positively with elongation.
- Intervention effect Mannose scarcely changed root diameter.
- Intervention effect 2-deoxyglucose caused marked root swelling.
- Intervention effect Tunicamycin caused swelling similar to 2-deoxyglucose.
- Intervention effect Mannose inhibited root elongation rate by 90% within 24 hours.
- Intervention effect Mannose reduced elongation rate to zero after a further two days.
- Observation The saturating mannose dose was 30 mM with 3% sucrose.
- Observation The saturating mannose dose was 0.3 mM without sucrose.
- Intervention effect Cell production rate was little affected during the first two days of mannose treatment.
- Intervention effect Nonphosphorylatable sugar analogs did not reproduce mannose inhibition of root elongation.
- Intervention effect Changing medium phosphate levels did not affect mannose inhibition.
- Intervention effect Mannoheptulose largely prevented mannose inhibition.
- Intervention effect Fructose largely prevented mannose inhibition.
- Mechanism The authors propose hexokinase-mediated sugar signaling as the route for mannose inhibition.
