Summary • Fusaric acid (FA) is a toxin produced by Fusarium species. Most studies on FA have reported toxic effects (for example, alteration of cell growth, mitochondrial activity and membrane permeability) at concentrations greater than 10−5 m.

Root hairs are a primary site for nutrient absorption and for initiation of signalling processes linked to variations of the root environment:plant-microbe interactions or abiotic changes. In many of these cases, the earliest detectable response is t

The electrical potential across the plasmalemma and the tonoplast were recorded, in Catharanthus roseus cells, by pushing a glass microelectrode through a cell with the tip consecutively in the cell wall, the cytoplasm and the vacuole. The electrical

45 ref.; The auxin-binding protein 1 (ABP1) has been proposed to be involved in the perception of the phytohormone at the plasma membrane. Site-directed mutagenesis was performed on highly conserved residues at the C terminus of ABP1 to investigate t

Nitrate Uptake in Catharanthus Roseus Cells: Electrophysiological Effects

Autor: R. Kiolle, U. Bousquet, Jean-Pierre Rona, Monique Convert, D. Cornel, G. Marigo, A. M. Pennarun, M. Monestiez

Publikováno v: Inorganic Nitrogen in Plants and Microorganisms ISBN: 9783642758140

Data on electrophysiological parameters of nitrate uptake are rather rare in plant cells. The distinction between the electrical effect of NO3 − at the plasmalemma and at the tonoplast turns out to be too complex for a heterogeneously polarized sys
