Potassium transport and plant salt tolerance.
Salinity is a major abiotic stress affecting approximately 7% of the world's total land area resulting in billion dollar losses in crop production around the globe. Recent progress in molecular… Expand
Plant Salt Tolerance
The patch-clamp technique was designed to measure any electrogenic transport across the whole cell and organelle (vacuolar) membranes and excised membrane patches. Here, we describe preparation of… Expand
Extracellular Ca2+ Ameliorates NaCl-Induced K+ Loss from Arabidopsis Root and Leaf Cells by Controlling Plasma Membrane K+-Permeable Channels1
Calcium can ameliorate Na+ toxicity in plants by decreasing Na+ influx through nonselective cation channels. Here, we show that elevated external [Ca2+] also inhibits Na+-induced K+ efflux through… Expand
Arabidopsis root K+-efflux conductance activated by hydroxyl radicals: single-channel properties, genetic basis and involvement in stress-induced cell death
Reactive oxygen species (ROS) are central to plant stress response, signalling, development and a multitude of other processes. In this study, the plasma-membrane hydroxyl radical (HR)-activated K+… Expand
Screening plants for salt tolerance by measuring K+ flux: a case study for barley
Development of salt-tolerant genotypes is central both to remediation of salinity-affected land and to meet increasing global food demand, which has been driving expansion of cropping into marginal… Expand

BACKGROUND Global annual losses in agricultural production from salt-affected land are in excess of US$12 billion and rising. At the same time, a significant amount of arable land is becoming lost to… Expand
Arabidopsis Protein Kinase PKS5 Inhibits the Plasma Membrane H+-ATPase by Preventing Interaction with 14-3-3 Protein
Regulation of the trans-plasma membrane pH gradient is an important part of plant responses to several hormonal and environmental cues, including auxin, blue light, and fungal elicitors. However,… Expand
Salinity-induced ion flux patterns from the excised roots of Arabidopsis sos mutants
The SOS signal-transduction pathway is known to be important for ion homeostasis and salt tolerance in plants. However, there is a lack of in planta electrophysiological data about how the changes in… Expand
Ion Transport in Halophytes
The increasing problem of global land salinisation and associated multibillion dollar losses in crop production require a better understanding of key physiological mechanisms conferring salinity… Expand
ROS homeostasis in halophytes in the context of salinity stress tolerance.
Halophytes are defined as plants that are adapted to live in soils containing high concentrations of salt and benefiting from it, and thus represent an ideal model to understand complex physiological… Expand
