Tree differences in primary and secondary growth drive convergent scaling in leaf area to sapwood area across Europe [PDF]

open access: yes, 2018
open28siTrees scale leaf (AL) and xylem (AX) areas to couple leaf transpiration and carbon gain with xylem water transport. Some species are known to acclimate in AL : AX balance in response to climate conditions, but whether trees of different species ...

Transport of Sodium into the Xylem Exudate of Tobacco [PDF]

open access: yesPlant Physiology, 1972
When tobacco (Nicotiana tabacum L. var. Virginia Gold) plants were pretreated with Na ((22)Na) several days before detopping, from 2.3 to 4.9% of Na previously accumulated in roots appeared in the xylem exudate in 7 days after detopping. Na from the external medium, however, was readily transported to the exudate.

Pneumatic Method to Measure Plant Xylem Embolism

open access: yesBio-Protocol, 2018
Embolism, the formation of air bubbles in the plant water transport system, has a major impact on plant water relations. Embolism formation in the water transport system of plants disrupts plant water transport capacity, impairing plant functioning and ...

Real-time imaging of pulvinus bending in Mimosa pudica [PDF]

open access: yes, 2019
Mimosa pudica is a plant that rapidly shrinks its body in response to external stimuli. M. pudica does not perform merely simple movements, but exhibits a variety of movements that quickly change depending on the type of stimuli.

The dynamics of embolism refilling in abscisic acid (ABA)-deficient tomato plants. [PDF]

open access: yes, 2012
Plants are in danger of embolism formation in xylem vessels when the balance between water transport capacity and transpirational demand is compromised.

The water relations and xylem attributes of albino redwood shoots (Sequioa sempervirens (D. Don.) Endl.). [PDF]

open access: yesPLoS ONE, 2018
Plants that lack chlorophyll are rare and typically restricted to holoparasites that obtain their carbon, water and mineral resources from a host plant.

The physiological resilience of fern sporophytes and gametophytes: advances in water relations offer new insights into an old lineage

open access: yesFrontiers in Plant Science, 2013
Ferns are some of the oldest vascular plants in existence and they are the second most diverse lineage of tracheophytes next to angiosperms. Recent efforts to understand fern success have fo-cused on the physiological capacity and stress tolerance of ...

Nitrate Transport Rate in the Xylem of Tomato Plants Grafted onto a Vigorous Rootstock

open access: yesAgronomy, 2020
Vigorous interspecific rootstocks increase nitrogen (N) uptake in tomato plants but limited information is available on xylem transport rate. Non-grafted and self-grafted tomato plants cv.

Distribution of xylem hydraulic resistance in fruiting truss of tomato influenced by water stress [PDF]

open access: yes, 2003
In this study xylem hydraulic resistances of peduncles (truss stalk), pedicels (fruit stalk) and the future abscission zone (AZ) halfway along the pedicel of tomato (Lycopersicon esculentum L.) plants were directly measured at different stages of fruit ...

Auxin-responsive DR5 promoter coupled with transport assays suggest separate but linked routes of auxin transport during woody stem development in Populus.

open access: yesPLoS ONE, 2013
Polar auxin transport (PAT) is a major determinant of plant morphology and internal anatomy with important roles in vascular patterning, tropic growth responses, apical dominance and phyllotactic arrangement.
