Predicting stomatal responses to the environment from the optimization of photosynthetic gain and hydraulic cost.
Stomatal regulation presumably evolved to optimize CO2 for H2 O exchange in response to changing conditions. If the optimization criterion can be readily measured or calculated, then stomatalExpand

Plant xylem hydraulics: What we understand, current research, and future challenges.
Herein we review the current state-of-the-art of plant hydraulics in the context of plant physiology, ecology, and evolution, focusing on current and future research opportunities. We explain theExpand

Heritability of Ulmus minor resistance to Dutch elm disease and its relationship to vessel size, but not to xylem vulnerability to drought
Dutch elm disease (DED) is a vascular wilt disease that causes the occlusion and cavitation of xylem vessels. Therefore,it is hypothesized that those elms that are less vulnerable to cavitation byExpand

Excising stem samples underwater at native tension does not induce xylem cavitation.
Xylem resistance to water stress-induced cavitation is an important trait that is associated with drought tolerance of plants. The level of xylem cavitation experienced by a plant is often assessedExpand

A stomatal control model based on optimization of carbon gain versus hydraulic risk predicts aspen sapling responses to drought.
Empirical models of plant drought responses rely on parameters that are difficult to specify a priori. We test a trait- and process-based model to predict environmental responses from an optimizationExpand

The standard centrifuge method accurately measures vulnerability curves of long-vesselled olive stems.
The standard centrifuge method has been frequently used to measure vulnerability to xylem cavitation. This method has recently been questioned. It was hypothesized that open vessels lead toExpand

Large volume vessels are vulnerable to water-stress-induced embolism in stems of poplar
Xylem vessels interconnect to form the vessel network that is responsible for long-distance water transport through the plant. As plants dehydrate, the water column within vessels cavitates and gasExpand

Seven Ulmus minor clones tolerant to Ophiostoma novo-ulmi registered as forest reproductive material in Spain
Abstract: The Spanish elm programme began in 1986 in response to the devastating impact of Dutch elm disease on natural elm stands and urban trees. Its main objectives were to conserve remainingExpand

Extending glacial refugia for a European tree: genetic markers show that Iberian populations of white elm are native relicts and not introductions
Conservation policies usually focus on in situ protection of native populations, a priority that requires accurate assessment of population status. Distinction between native and introduced statusExpand

Massive sequencing of Ulmus minor’s transcriptome provides new molecular tools for a genus under the constant threat of Dutch elm disease
Elms, especially Ulmus minor and U. americana, are carrying out a hard battle against Dutch elm disease (DED). This vascular wilt disease, caused by Ophiostoma ulmi and O. novo-ulmi, appeared in theExpand
