Effect of Indole-3-acetic Acid on Membrane Potentials of Oat Coleoptile Cells.
This paper reports an effect of indole-3-acetic acid on cell membrane potentials. Solutions with increasing IAA concentrations (from 109 to 10-7 M) make membrane potentials of coleop-tile cells more negative. This effect of IAA, which occurs at concentrations that also stimulate tissue elongation, was found inadvertently in the course of an experiment on the effect of IAA on cell wall potential...
متن کاملIndole-3-acetic acid and fusicoccin cause cytosolic acidification of corn coleoptile cells.
Microelectrodes were used to measure simultaneously the effects of indole-3-acetic acid (IAA) on membrane potential and cytosolic pH of corn coleoptile cells. IAA caused an initial depolarization followed by hyperpolarization, the latter displaying rhythmic oscillations. The extent of the changes in membrane potential was dependent on IAA concentration, and hyperpolarization, but not depolariza...
متن کاملGrowth and indole-3-acetic acid biosynthesis of Azospirillum brasilense Sp245 is environmentally controlled.
Batch and fed batch cultures of Azospirillum brasilense Sp245 were conducted in a bioreactor. Growth response, IAA biosynthesis and the expression of the ipdC gene were monitored in relation to the environmental conditions (temperature, availability of a carbon source and aeration). A. brasilense can grow and produce IAA in batch cultures between 20 and 38 degrees C in a standard minimal medium...
متن کاملGrowth of Parthenocissus tricuspidata tissue cultured on media containing aza analogues of indole-3-acetic acid & indole-3-propionic acid.
Several years ago, Robison and Robison (5) reported the synthesis of some compounds of biological interest. Among these were 7-aza-indole-3-acetic acid (AIAA) and 7-aza-indole-3-propionic acid (AIPA), aza analogues of indole-3-acetic acid (IAA), and indole-3-propionic acid (IPA). It was apparent that such compounds might be anti-metabolites of auxin, in the same manner that azaguanine has prove...
