Owing to its detrimental effect on plant growth, salinity is an increasing worldwide problem
for agriculture. To understand the molecular mechanisms activated in response to salt in …

Sodium (Na+) is toxic to most plants, but the molecular mechanisms of plant Na+ uptake and
distribution remain largely unknown. Here we analyze Arabidopsis lines disrupted in the …

Increases in cytosolic free Ca2+ ([Ca2+] cyt) are common to many stress‐activated
signalling pathways, including the response to saline environments. We have investigated …

Extracellular ATP regulates higher plant growth and adaptation. The signalling events may
be unique to higher plants, as they lack animal purinoceptor homologues. Although it is …

Calcineurin (CaN) is a Ca2+-and calmodulin-dependent protein phosphatase (PP2B) that,
in yeast, is an integral intermediate of a salt-stress signal transduction pathway that effects …

Detrimental effects of salinity on plants are known to be partially alleviated by external Ca2+.
Previous work demonstrated that the Arabidopsis SOS3 locus encodes a Ca2+‐binding …

A central question is how specificity in cellular responses to the eukaryotic second
messenger Ca2+ is achieved. Plant guard cells, that form stomatal pores for gas exchange …

Excessive Na+ in soils inhibits plant growth. Here, we report that Na+ stress triggers primary
calcium signals specifically in a cell group within the root differentiation zone, thus forming a" …

The endodermal tissue layer is found in the roots of vascular plants and functions as a
semipermeable barrier, regulating the transport of solutes from the soil into the vascular …

Higher plants take up nutrients via the roots and load them into xylem vessels for
translocation to the shoot. After uptake, anions have to be channeled toward the root xylem …
