Other claims from this paper (12)
- Intervention effect Indole-3-acetic acid stimulated elongation of rice coleoptiles.
- Intervention effect 1-Aminocyclopropane-1-carboxylic acid, the ethylene precursor, stimulated elongation of rice coleoptiles.
- Observation Osmotic pressure of the rice coleoptile cell sap decreased during elongation.
- Intervention effect Indole-3-acetic acid at 30 µM accelerated the decrease in osmotic pressure in the early growth stage when aminooxyacetic acid was present.
- Intervention effect 1-Aminocyclopropane-1-carboxylic acid at 30 µM did not influence the decrease in osmotic pressure.
- Intervention effect Indole-3-acetic acid decreased the minimum stress-relaxation time and the relaxation rate of the rice coleoptile cell wall.
- Intervention effect 1-Aminocyclopropane-1-carboxylic acid decreased the minimum stress-relaxation time and the relaxation rate of the rice coleoptile cell wall.
- Mechanism Auxin and ethylene induce rice coleoptile elongation by stimulating cell wall loosening.
- Intervention effect 1-Aminocyclopropane-1-carboxylic acid increased glucose in hemicelluloses of rice coleoptile cell walls in the early growth stage.
- Intervention effect Indole-3-acetic acid decreased glucose in hemicelluloses of rice coleoptile cell walls in the last growth phase.
- Intervention effect 1-Aminocyclopropane-1-carboxylic acid decreased glucose in hemicelluloses of rice coleoptile cell walls in the last growth phase.
- Intervention effect Indole-3-acetic acid decreased hydroxyproline and glucosamine levels per unit dry weight of the cell wall.
