Oligomeric degradation products of alginate elicited a respiratory and oxidative burst in the sporophytes of the kelp Laminaria digitata. The generation of activated oxygen species (AOS), O2 −, and H2O2 was detected at the single cell level, using

On the basis of the anion content of in vitro-cultured Arabidopsis plantlets, we explored the selectivity of the voltage-dependent anion channel of the plasma membrane of hypocotyl cells. In the whole-cell configuration, substitution of cytosolic Cl

Summary The metabolism by suspension-cultured tobacco cells of oligogalacturonides was investigated. Dodecagalacturonic acid-[3H]galactitol induces a rapid and transient alkalinization of the incubation medium resulting in part from enhanced K+ efflu

Membrane depolarization associated with changes in transmembrane cation and anion effluxes constitute early events in the signalling cascades which mediate elicitor-induced defense reactions in plant cells. The aim of the present study is to investig

The biological activity of reducing-end-modified oligogalacturonides was quantified in four tobacco (Nicotiana tabacum) tissue culture bioassays. The derivatives used were oligogalacturonides with the C-1 of their reducing end (a) covalently linked t

Auxin is transported across the plasma membrane of plant cells by diffusion and by two carriers operating in opposite directions, the influx and efflux carriers. Both carriers most likely play an important role in controlling auxin concentration and

Plasma membrane anion channels are thought to play important roles in osmoregulation and signal transduction in higher plant cells. Knowledge of their pharmacology and regulation is of importance to unravel their physiological functions. In this stud

Pathogen recognition at the plant cell surface typically results in the initiation of a multicomponent defense response. Transient influx of Ca 2+ across the plasma membrane is postulated to be part of the signaling chain leading to pathogen resistan

The discovery of water channel proteins named aquaporins has shed new light on the molecular mechanisms of transmembrane water transport in higher plants. As with their animal counterparts, plant aquaporins belong to the large MIP family of transmemb
