Drought stress, caused by lack of precipitation or irrigation, is one of the most challenging
problems in crop production in the US and worldwide. Drought alone affects 45% of the …

Current technologies have changed biology into a data-intensive field and significantly
increased our understanding of signal transduction pathways in plants. However, global …

Arabidopsis thaliana is a long established model species for plant molecular biology,
genetics and genomics, and studies of A. thaliana gene function provide the basis for …

Crop performance is severely affected by high salt concentrations in soils. To engineer more
salt-tolerant plants it is crucial to unravel the key components of the plant salt-tolerance …

Trehalose is a quantitatively important compatible solute and stress protectant in many
organisms, including green algae and primitive plants. These functions have largely been …

Scarcity of water is a severe environmental constraint to plant productivity. Drought-induced
loss in crop yield probably exceeds losses from all other causes, since both the severity and …

Leaf senescence in winter deciduous species signals the transition from the active to the
dormant stage. The purpose of leaf senescence is the recovery of nutrients before the leaves …

Abiotic stresses, such as drought, salinity, extreme temperatures, chemical toxicity and
oxidative stress are serious threats to agriculture and the natural status of the environment …

Tolerance to high soil [Na+] involves processes in many different parts of the plant, and is
manifested in a wide range of specializations at disparate levels of organization, such as …

Salinity tolerance comes from genes that limit the rate of salt uptake from the soil and the
transport of salt throughout the plant, adjust the ionic and osmotic balance of cells in roots …
