Since the first recordings of single potassium channel activities in the plasma membrane of
guard cells more than 25 years ago, patch-clamp studies discovered a variety of ion …

Stomata are an attractive experimental system in plant biology, because the responses of
guard cells to environmental signals can be directly linked to changes in the aperture of …

Lysosomes have fundamental physiological roles and have previously been implicated in
Parkinson's disease,,,–. However, how extracellular growth factors communicate with …

Survival in the wild requires organismal adaptations to the availability of nutrients.
Endosomes and lysosomes are key intracellular organelles that couple nutrition and …

Endosomes, lysosomes and lysosome-related organelles are emerging as important Ca2+
storage cellular compartments with a central role in intracellular Ca2+ signalling …

Although Mg2+ is essential for a myriad of cellular processes, high levels of Mg2+ in the
environment, such as those found in serpentine soils, become toxic to plants. In this study …

Nitrate, the major nitrogen source for most plants, is widely used as a fertilizer and as a
result has become a predominant freshwater pollutant. Plants need nitrate for growth and …

Inorganic phosphate (Pi) is stored in the vacuole, allowing plants to adapt to variable Pi
availability in the soil. The transporters that mediate Pi sequestration into vacuole remain …

Potassium is the most abundant ion to face both plasma and organelle membranes.
Extensive research over the past seven decades has characterized how K+ permeates the …

Plant cells contain two major pools of K+, one in the vacuole and one in the cytosol. The
behavior of K+ concentrations in these pools is fundamental to understanding the way this …
