To investigate the contribution of different parts of the root system to total sap flow and leaf
xylem abscisic acid (ABA) concentration ([X‐ABA] leaf), individual sunflower (Helianthus …

The effects of different irrigation techniques on leaf xylem ABA concentration ([X-ABA] leaf)
were compared in tomato (Lycopersicon esculentum Mill.). During partial rootzone drying …

Partial rootzone drying (PRD) is an irrigation technique where water is distributed unevenly
to the root system such that part is irrigated while the remainder is allowed to dry the soil …

Abscisic acid (ABA) moving from roots to shoots in the transpiration stream is a potential
hormonal message integrating perception of a root stress with adaptive changes in the …

Stomatal sensitivity to root signals induced by soil drying may vary between environments
and plant species. This is likely to be a result of the interactions and modulations among root …

To determine how root‐to‐shoot abscisic acid (ABA) signalling is regulated by vertical soil
moisture gradients, root ABA concentration ([ABA] root), the fraction of root water uptake …

Abscisic acid (ABA) affects plant metabolism and water transfers via multiple mechanisms at
cell, organ and whole plant levels. These mechanisms translate into contradictory effects on …

To determine whether root‐to‐shoot signalling of soil moisture heterogeneity depended on
root distribution, wild‐type (WT) and abscisic acid (ABA)‐deficient (Az34) barley (Hordeum …

Patterns of root abscisic acid (ABA) accumulation ([ABA] root), root water potential (Ψroot),
and root water uptake (RWU), and their impact on xylem sap ABA concentration ([X-ABA]) …

When soil moisture is heterogeneous, sap flow from, and ABA status of, different parts of the
root system impact on leaf xylem ABA concentration ([X-ABA] leaf). The robustness of a …
