Soil salinity is a major abiotic stress in plant agriculture worldwide. This has led to research
into salt tolerance with the aim of improving crop plants. However, salt tolerance might have …

Biological N2 fixation represents the major source of N input in agricultural soils including
those in arid regions. The major N2-fixing systems are the symbiotic systems, which can play …

Although they represent only 2% of terrestrial plant species, halophytes are present in about
half the higher plant families and represent a wide diversity of plant forms. Despite their …

The Arabidopsis thaliana SOS2 and SOS3 genes are required for intracellular Na+ and K+
homeostasis and plant tolerance to high Na+ and low K+ environments. SOS3 is an EF hand …

A large genetic screen for sos (for s alt o verly s ensitive) mutants was performed in an
attempt to isolate mutations in any gene with an sos phenotype. Our search yielded 28 new …

This is a completely revised edition of the previously titled Solute Movement in the Soil-Root
System. It describes in detail how plant nutrients and other solutes move in the soil in …

Proline is an important component of salt‐stress responses of plants. In this study the role of
proline as part of salt‐stress signalling in the desert plant Pancratium maritimum L. was …

To begin to determine which genes are essential for salt tolerance in higher plants, we
identified four salt-hypersensitive mutants of Arabidopsis by using a root-bending assay on …

Cells respond to salt stress by osmolyte synthesis and by increase of K+ uptake and Na+
efflux at the plasma membrane and of Na+ accumulation at the vacuole. This cellular level of …

Proline is a common compatible osmolyte in higher plants. Proline accumulation in
response to water stress and salinity is preceded by a rapid increase of the mRNA level of …
