Evolution of Water Transport and Xylem Structure
@article{Sperry2003EvolutionOW, title={Evolution of Water Transport and Xylem Structure}, author={John S. Sperry}, journal={International Journal of Plant Sciences}, year={2003}, volume={164}, pages={S115 - S127} }
Land plants need water to replace the evaporation that occurs while atmospheric CO2 is diffusing into photosynthetic tissue. [] Key Result Transport improvements appeared as water demand increased and CO2 dropped to current values in the Carboniferous and Permian. Stomatal regulation and high‐conductivity conduits permitted larger plants and a transition from poikilohydric to homoiohydric water relations. The evolution of conduits from hydroids through tracheids to vessels reflects the need to balance…

Current empirical evidence suggests that phloem failure resulting fromphloem turgor collapse is the more likely mechanism at least in relatively isohydric plants, but which one of these dominates depends on the hydraulic permeability ofPhloem conduit walls.
CO2‐forced evolution of plant gas exchange capacity and water‐use efficiency over the Phanerozoic
- Environmental ScienceGeobiology
- 2009
The calculated steady rise in stomatal conductance over the Phanerozoic is consistent with independent evidence for the evolution of plant hydraulic capacity, implying coordinated and sustained increase in gas exchange capacity and hydraulic capacity parallel long-term increases in land plant diversity.
ADAPTIVE VARIATION IN THE VULNERABILITY OF WOODY PLANTS TO XYLEM CAVITATION

The evolution of increased resistance to cavitation as a mechanism of drought tolerance may be of primary importance in evergreen angiosperms and conifers and the evolutionary basis for a trade-off between cavitation resistance and water transport capacity is weak.

Comparisons of photosynthetic, hydraulic and biomass properties in a closely related C3 Tarenaya hassleriana and a C4 Cleome gynandra are compared to support the previous findings that WUE, and any changes that affectWUE, contribute to xylem evolution in plants.

The model supported Zimmermann's plant segmentation hypothesis, whereby it was suggested that plants are designed hydraulically to sacrifice highly vulnerable minor branches and thus improve the water balance of remaining parts.

Xylem vessels in grapevines growing in New England contained air over winter and yet filled with xylem sap and recovered their maximum hydraulic conductance during the month before leaf expansion in late May, suggesting that the decrease in permeability with hydration is due to formation of water films across pores in intervascular pit membranes.

The hydraulic approach can improve the understanding of the coupling of canopy processes to soil environment, and the adaptive significance of stomatal behaviour, and allow the prediction of water use as a function of soil environment and plant architectural and xylem traits.

During dehydration and rehydration cycles stems showed considerable shrinking and swelling and unusual knob-like structures of unknown chemical composition were observed on the outer surface of xylem vessels, which may be related to the ability of the stem to withstand the mechanical stresses associated with this shrinkage and swelling.

The hypothesis that water stress-induced xylem embolism is caused by air aspirated into functional vessels from neighboring embolized ones via pores in intervessel pit membranes is investigated and experiments with sugar maple support the hypothesis.
Hydraulic architecture of some diffuse-porous trees

The rate of flow of a dilute KCl solution through sections of stem, branches, and twigs was measured and expressed in microlitres per hour, under conditions of gravity flow, to measure leaf-specific conductivity (LSC), which is not uniform throughout the tree, LSC of the stem being higher than that of branches.
