e0“The parallel increase in membrane potential difference and growth rate during the time-course of the SGR indicates a possible role for PM H + -ATPase in the establishment of the SGR in maize coleoptile segments”

Other claims from this paper (5)
- Observation Upright decapitated maize coleoptile segments show strong spontaneous growth three hours after decapitation.
- Intervention effect Inverting decapitated segments markedly reduces the latent period of spontaneous growth.
- Observation Intact-tip coleoptile segments show a weak transient spontaneous growth response when upright.
- Intervention effect Intact-tip coleoptile segments show a typical spontaneous growth response when inverted.
- Observation The observations are inconsistent with the proposed time-dependent increase in auxin sensitivity causing spontaneous growth.
