Other claims from this paper (8)
- Observation Hexose sugars accumulated asymmetrically in graviresponding maize pulvini.
- Observation Acid invertase activity increased asymmetrically across the pulvinus.
- Intervention effect Gravistimulation asymmetrically induced Ivr2 expression.
- Intervention effect Auxin transport inhibition blocked Ivr2 transcript accumulation.
- Observation A transient free IAA gradient appeared after gravistimulation began.
- Intervention effect Applying the inhibitor after the IAA gradient peak did not inhibit gravitropic responses.
- Intervention effect IAA stimulated Ivr2 transcript accumulation without gravistimulation.
- Intervention effect Cycloheximide inhibited gravity- and IAA-stimulated Ivr2 transcript increases.
