TLDR
In this article, the response of transpiration rate to changes in atmospheric VPD was measured at two different temperatures in a growth chamber, and the effect of growth temperature on transpiration was evident when plants were grown at low temperature (22/18°C) and measured at higher temperature (30°C).About:

TL;DR: Xylem pit anatomy that makes xylem less “leaky” and prone to cavitation warrants further exploration holding promise that such traits may improve plant productivity in water-limited environments without negatively impacting yield under adequate water conditions.

Transpiration efficiency: new insights into an old story
TL;DR: A new lysimetric method for assessing TE gravimetrically throughout the entire cropping cycle has clearly established an absence of relationships between TE and total water use, which dismisses previous claims that high TE may lead to a lower production potential.

Root hydraulics: The forgotten side of roots in drought adaptation
TL;DR: In this article, the root system from the angle of water extraction, using data from a lysimetric system that allows monitoring and comparing plant water use over the entire crop life cycle and yield, and analyze whether and how differences in water extraction lead to improved yield across different crops.

Physiological and environmental regulation of stomatal conductance, photosynthesis and transpiration: a model that includes a laminar boundary layer
TL;DR: In this article, a system of models for the simulation of gas and energy exchange of a leaf of a C3 plant in free air is presented, where the physiological processes are simulated by sub-models that: (a) give net photosynthesis (An) as a function of environmental and leaf parameters and stomatal conductance (gs); (b) give g, as well as the concentration of CO2 and H2O in air at the leaf surface and the current rate of photosynthesis of the leaf.

Thermal acclimation and the dynamic response of plant respiration to temperature
Owen K. Atkin,Mark G. Tjoelker +1 more
TL;DR: The underlying mechanisms responsible for the dynamic response of plant respiration to short and long-term temperature changes are discussed, including shifts in the control exerted by maximum enzyme activity at low temperature and substrate limitations at high temperature.

Survey and synthesis of intra- and interspecific variation in stomatal sensitivity to vapour pressure deficit
Ram Oren,John S. Sperry,Gabriel G. Katul,Diane E. Pataki,Brent E. Ewers,Nathan Phillips,Karina V. R. Schäfer +6 more
TL;DR: In this paper, the authors analyzed data from a variety of sources employing both porometric and sap flux estimates of stomatal conductance (gs) to evaluate the hypothesis that stomata sensitivity is proportional to the magnitude of gs at low D (£ 1k Pa).

Breeding for Yield Potential and Stress Adaptation in Cereals
TL;DR: The physiological basis of crop yield and its response to stresses is highlighted, with special emphasis on drought, and ways to improve the efficiency of crop breeding through a better physiological understanding by both conventional and molecular methods are discussed.

A reinterpretation of stomatal responses to humidity
TL;DR: In this paper, a reanalysis of 52 sets of measurements on 16 species supports the conclusion of Mott & Parkhurst that stomata respond to the rate of transpiration (E) rather than to humidity per se.
