Nearly all plant families, represented across most major biomes, absorb water directly
through their leaves. This phenomenon is commonly referred to as foliar water uptake …

The absorption of water and solutes by plant leaves has been recognised since more than
two centuries. Given the polar nature of water and solutes, the mechanisms of foliar uptake …

Most aerial plant surfaces are covered with a lipid-rich cuticle, which is a barrier for the
bidirectional transport of substances between the plant and the surrounding environment …

Salt stress is a complex trait that poses a grand challenge in developing new crops better
adapted to saline environments. Some plants, called recretohalophytes, that have naturally …

Trichomes are epidermal outgrowths on plant shoots. Their roles in protecting plants against
herbivores and in the biosynthesis of specialized metabolites have long been recognized …

Watersheds are the basic unit of Earth's terrestrial systems and are therefore ideal units for
the study of critical zones (CZs). However, grand challenges remain regarding the …

Non‐rainfall water inputs (NRWIs) are the least studied hydrological components in most
ecosystems. These NRWI components potentially play an important role in ecosystem …

The mangrove Avicennia marina adjusts internal salt concentrations by foliar salt secretion.
Deliquescence of accumulated salt causes leaf wetting that may provide a water source for …

As an additional source of water to plants besides rainfall, dew may have a positive impact
on vegetation in the arid ecosystems. Knowledge regarding dew formation characteristics …

The current review focuses on the contribution of non‐rainfall water (NRW) to arid and
semiarid regions (with a focus on the Negev), where NRW may provide a constant source of …
