Nitrogen (N) availability is a major factor determining plant growth and productivity. Plants
acquire inorganic N from the soil, mainly in the form of nitrate and ammonium. To date …

The apoplast is an interconnected compartment with a thin water-film that alkalinizes under
stress. This systemic pH increase may be a secondary effect without functional implications …

The pH of intracellular compartments is essential for the viability of cells. Despite its
relevance, little is known about the pH of these compartments. To measure pH in vivo, we …

Since water spontaneously ionizes, protons cannot be removed from the medium: their free
concentration in cells must be regulated through actively controlling H+-related transport …

The suitability of the infiltration‐centrifugation method for collection of apoplastic fluid from
intact leaves was evaluated for different plant species. Large differences with respect to …

For noninvasive in vivo measurements of intra-and extracellular ion concentrations, we
produced transgenic Arabidopsis expressing pH and calcium indicators in the cytoplasm …

Aims Production of biomass and yield in natural and agronomic conditions depend on the
endogenous growth capacity of plants and on the environmental conditions constraining it …

Background pH regulation is the result of a complex interaction of ion transport, H+ buffering,
H+-consuming and H+-producing reactions. Cells under anoxia experience an energy crisis; …

Plants are much more dynamic than we usually expect them to be. This dynamic behaviour
is of paramount importance for their performance under natural conditions, when resources …

NADH and NAD+ are a ubiquitous cellular redox couple. Although the central role of NAD in
plant metabolism and its regulatory role have been investigated extensively at the …
