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 …

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]) …

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 …

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 …

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 …

Root water uptake is influenced by root system architecture, which is determined by root
growth and branching and the hydraulics of root cells and tissues. The phytohormone …

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 …

To investigate the influence of different growing substrates (two mineral, two organic) on root
xylem ABA concentration ([ABA] root) and the contribution of the drying root system to total …

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 …

Previous studies with partial rootzone drying (PRD) irrigation demonstrated that alternating
the wet and dry parts of the rootzone (PRD-Alternated) increased leaf xylem ABA …
