| Ethylene was found to reverse the direction of gravity-induced lateral auxin transport and to cause an accumulation of auxin in the physically upper sides of horizontally placed pea shoots. The pea shoot displayed a slightly positive (downward) geotropic curvature in the presence of applied ethylene. Golgi bodies were found to be distributed preferentially in the bottom halves of cells as against the top halves following geotropic stimulation, and this pattern of intracellular distribution of dictyosomes was also reversed by ethylene treatment. Intracellular displacement of amyloplsts as a result fo geotropic induction was not reversed by the action of ethylene. In view of a positive correlation between the direction of auxin movement and the displacement patern of dictyosomes, it is suggested that the Golgi bodies are involved in the perception of gravity and/or subsequent redistribution of auxin or differential elongation in geotropism. |
