We present unresolved questions in plant abiotic stress biology as posed by 15 research
groups with expertise spanning eco-physiology to cell and molecular biology. Common …

Aquaporins are membrane channels that facilitate the transport of water and small neutral
molecules across biological membranes of most living organisms. In plants, aquaporins …

Because of intense transpiration and growth, the needs of plants for water can be immense.
Yet water in the soil is most often heterogeneous if not scarce due to more and more …

Plant growth and development are dependent on tight regulation of water movement. Water
diffusion across cell membranes is facilitated by aquaporins that provide plants with the …

Background Oxidation-reduction and acid–base reactions are essential for the maintenance
of all living organisms. However, redox potential (Eh) has received little attention in …

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 …

Aquaporins (AQP) are channel proteins belonging to the Major Intrinsic Protein (MIP)
superfamily that play an important role in plant water relations. The main role of aquaporins …

A common effect of several abiotic stresses is to cause tissue dehydration. Such dehydration
is caused by the imbalance between root water uptake and leaf transpiration. Under some …

The role of γ-aminobutyric acid (GABA) as a signal in animals has been documented for
over 60 years. In contrast, evidence that GABA is a signal in plants has only emerged in the …

Flooding regimes of different depths and durations impose selection pressures for various
traits in terrestrial wetland plants. Suites of adaptive traits for different flooding stresses, such …
