Salt tolerance conferred by overexpression of a vacuolar Na+/H+ antiport in Arabidopsis.
Agricultural productivity is severely affected by soil salinity. One possible mechanism by which plants could survive salt stress is to compartmentalize sodium ions away from the cytosol.Expand

Sodium transport in plant cells.
Salinity limits plant growth and impairs agricultural productivity. There is a wide spectrum of plant responses to salinity that are defined by a range of adaptations at the cellular and theExpand

Transgenic salt-tolerant tomato plants accumulate salt in foliage but not in fruit
Transgenic tomato plants overexpressing a vacuolar Na+/H+ antiport were able to grow, flower, and produce fruit in the presence of 200 mM sodium chloride. Although the leaves accumulated high sodiumExpand

Characterizing the Saltol Quantitative Trait Locus for Salinity Tolerance in Rice
This study characterized Pokkali-derived quantitative trait loci (QTLs) for seedling stage salinity tolerance in preparation for use in marker-assisted breeding. An analysis of 100 SSR markers on 140Expand

Salt Tolerance and Crop Potential of Halophytes
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 polyphyleticExpand

Delayed leaf senescence induces extreme drought tolerance in a flowering plant
Drought, the most prominent threat to agricultural production worldwide, accelerates leaf senescence, leading to a decrease in canopy size, loss in photosynthesis and reduced yields. On the basis ofExpand

The Arabidopsis Na+/H+ Antiporters NHX1 and NHX2 Control Vacuolar pH and K+ Homeostasis to Regulate Growth, Flower Development, and Reproduction[C][W]
This work examined the functions of NHX1 and NHX2, two members of the Arabidopsis thaliana Na+/H+ antiporter family, in cell growth and flower development, demonstrating that NHX1 and NHX2 regulateExpand

Reactive oxygen species, abiotic stress and stress combination.
Reactive oxygen species (ROS) play a key role in the acclimation process of plants to abiotic stress. They primarily function as signal transduction molecules that regulate different pathways duringExpand

The Arabidopsis Intracellular Na+/H+ Antiporters NHX5 and NHX6 Are Endosome Associated and Necessary for Plant Growth and Development[w]
This work demonstrates that two members of the Arabidopsis Na+/H+ antiporter family, NHX5 and NHX6, are critical for normal plant growth and response to stress. Experiments show that the two proteinsExpand
