Effects of anti-transpirants on transpiration and energy use in greenhouse cultivation [PDF]
, 2008 Greenhouse production in North-West Europe consumes a lot of energy. The energy is needed for heating the greenhouse and controlling air humidity. Transpiration of a crop increases the energy use.

Da Vinci's mischief: xylem conduits in the stems of woody plants do not furcate
New Phytologist, EarlyView.Summary The hydraulic architecture of plants is often modeled as a ‘furcating’ network, in which xylem conduits proliferate in number toward the stem apex, analogous to animal circulatory systems. Yet whether furcation actually occurs within woody stems remains untested, despite major implications for carbon costs and hydraulic efficiency.

Frontiers in Plant Science, 2015 Plants usually experience dynamic fluctuations of light intensities under natural conditions. However, the responses of mesophyll conductance, CO2 assimilation, and photorespiration to light fluctuation are not well understood.

Guard cell photorespiration controls stomata behavior and development
New Phytologist, EarlyView.Summary Photorespiration is traditionally viewed as a limitation to photosynthetic efficiency. However, it is mandatory for safeguarding the Calvin–Benson–Bassham cycle from inhibitory byproducts through Rubisco‐mediated oxidative misfire and is tightly integrated with primary metabolism.

Improved understanding of drought controls on seasonal variation in Mediterranean forest canopy CO2 and water fluxes through combined in situ measurements and ecosystem modelling [PDF]
, 2015 Water stress is a defining characteristic of Mediterranean ecosystems, and is likely to become more severe in the coming decades. Simulation models are key tools for making predictions, but our current understanding of how soil moisture controls ...

Evidence for regulation of transpiration in nonstomatal plants: insights from bryophyte gametophytes
New Phytologist, EarlyView.Kinetics of cell wall water vapor potential (Ψcw) and resistance of cell wall and plasmatic membrane to water flux in response to cytoplasmic water potential (Ψcyt) during dehydration. Ψcyt was calculated from the WC at any moment of the dehydration curve by using the relationship between −1/Ψw and WC of pressure volume curves and assuming Ψw = Ψcyt ...

Frontiers in Plant Science, 2019 Promotion of nonfood species production to marginal, degraded lands abandoned by mainstream agriculture is affected by extremes of water availability (droughts and floods), which have increased in frequency and intensity and account for severe yield ...

New Phytologist, EarlyView.Bulk leaf capacitance (Cbulk) in relation to bundle sheath area (BSA) and leaf dimensions in Alloteropsis semialata plants differing in photosynthetic type (C3, C3–C4 or C4) and ploidy level (2x, 6x or 12x). Summary The evolution of C4 photosynthesis requires biochemical innovations to be coordinated with anatomical modifications.

An Elite Haplotype of Nitrogen‐Use‐Efficiency Gene LHT5 Enhances Salt Tolerance in Rice
Plant Biotechnology Journal, EarlyView.ABSTRACT Amino acids serve as fundamental building blocks and signalling molecules in plants, orchestrating stress adaptation mechanisms against diverse biotic and abiotic environmental challenges. However, the mechanism by which plants alter their nutrient metabolism processes to coordinate nitrogen use efficiency (NUE) and salt tolerance remains ...
