Hydraulic lift: consequences of water efflux from the roots of plants
Abstract Hydraulic lift is the passive movement of water from roots into soil layers with lower water potential, while other parts of the root system in moister soil layers, usually at depth, areExpand

Nighttime Stomatal Conductance and Transpiration in C3 and C4 Plants1[W]
Incomplete stomatal closure during the night is observed in a diverse range of C3 and C4 species ([Fig. 1][1] ; Supplemental Table S1) and can lead to substantial nighttime transpirational waterExpand

Hydraulic lift: Substantial nocturnal water transport between soil layers by Artemisia tridentata roots
SummaryDiel soil water potential fluctuations reflected daytime depletion and nocturnal resupply of water in upper soil layers. Transpiration suppression experiments demonstrated that waterExpand

Genetics of drought adaptation in Arabidopsis thaliana: I. Pleiotropy contributes to genetic correlations among ecological traits
We examined patterns of genetic variance and covariance in two traits (i) carbon stable isotope ratio δ13C (dehydration avoidance) and (ii) time to flowering (drought escape), both of which areExpand

Physiological Genomics of Response to Soil Drying in Diverse Arabidopsis Accessions[W][OA]
This work examines the physiological and transcriptomic responses to soil drying in 17 diverse accessions of Arabidopsis thaliana, finding that acclimation to drought stress involved increasedExpand

Coping with herbivory: Photosynthetic capacity and resource allocation in two semiarid Agropyron bunchgrasses
SummaryAgropyron desertorum, a grazing-tolerant bunchgrass introduced to the western U.S. from Eurasia, and Agropyron spicatum, a grazing-sensitive bunchgrass native to North America, were examinedExpand

Identification and characterization of QTL underlying whole‐plant physiology in Arabidopsis thaliana: δ13C, stomatal conductance and transpiration efficiency
Water limitation is one of the most important factors lim- iting crop productivity world-wide and has likely been an important selective regime influencing the evolution of plant physiology.Expand

The physiological basis for genetic variation in water use efficiency and carbon isotope composition in Arabidopsis thaliana
Ecologists and physiologists have documented extensive variation in water use efficiency (WUE) in Arabidopsis thaliana, as well as association of WUE with climatic variation. Here, we demonstrateExpand
