Further evidence for the possible involvement of K+ channels in the revolving movement of twining shoots. Effects of aluminum ion
Arguments supplémentaires en faveur de l'implication de canaux K+ dans le mouvement révolutif des tiges volubiles. Effets de l'ion aluminium
Résumé
The effects of aluminum chloride on revolving movement have been investigated. At concentrations ranged from 4 ot 8 mM, A3/+ caused a marked slowing down of hte movement of twining Phaseolus vulgaris L. shoots without any effects on growth rate. K+ did not reverse this effect. These results are consistent with the previously proposed hypothesis that K+ channels are involved in the mechanism of the revolving movement.
