Growth Temperature Alters the Thermal Sensitivity of Mesophyll Conductance in Wild and Cultivated Tomato

Plant, Cell &Environment, EarlyView.
ABSTRACT Mesophyll conductance (gm) is a key component of internal CO2 diffusion and can limit photosynthesis in C3 leaves. Temperature responses of gm are commonly treated as intrinsic properties of the leaf, yet it remains unclear whether they acclimate to growth conditions. Here, we tested whether growth temperature alters the thermal sensitivity of

Novel Amino Acid Changes Increase Phosphoenolpyruvate Carboxylase Output in planta

Plant, Cell &Environment, EarlyView.
ABSTRACT Characterization of previously reported Arabidopsis mutants with increased aluminum (Al) resistance (alr) resulting from greater release of Al‐chelating malate identified three unique amino acid substitutions that each impacts PHOSPHOENOLPYRUVATE CARBOXYLASE 1, a key anaplerotic carbon fixation enzyme.

Photorespiration plays an important role in the regulation of photosynthetic electron flow under fluctuating light in tobacco plants grown under full sunlight

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.

Estimation of the mesophyll conductance to CO2 flux by three different methods

, 1992
The resistance to diffusion of CO2 from the intercellular airspaces within the leaf through the mesophyll to the sites of carboxylation during photosynthesis was measured using three different techniques.

Disentangling Thermal and Hydraulic Drivers of Stomatal Conductance Under Hot Versus Dry Vapour Pressure Deficit Increases Using Water‐Use Efficiency

Plant, Cell &Environment, EarlyView.
ABSTRACT Predicting plant functioning in a warming world requires capturing its divergent responses to hot versus dry vapour pressure deficit (VPD) increases. Stomatal responses to VPD are typically studied without disentangling the effects of RH and temperature, creating uncertainties for future plant functioning.

CO2 Fertilisation of Growth in Wild C4 Grasses may be Amplified by Upregulated Photosynthesis

Plant, Cell &Environment, EarlyView.
ABSTRACT Rising atmospheric CO2 is expected to have limited direct effects on C4 photosynthesis because the carbon‐concentrating mechanism maintains near‐saturating CO2 at Rubisco. Consequently, growth responses of C4 plants to elevated CO2 (eCO2) are generally attributed to indirect improvements in plant water relations.

Photosynthetic and Growth Responses of Arundo donax L. Plantlets Under Different Oxygen Deficiency Stresses and Reoxygenation

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 ...

Concurrent Increases in Root Phosphorus Acquisition and Leaf Phosphorus Resorption Underpin Enhanced Phosphorus Economy in Chickpea During Reproductive Development

Plant, Cell &Environment, EarlyView.
ABSTRACT Phosphorus (P) acquisition and leaf P‐use strategies are critical for reproductive success and productivity, yet, their developmental association during the reproductive phase remains unclear. Five chickpea accessions contrasting in P‐remobilisation efficiency (PRE) were grown in a temperature‐controlled glasshouse under moderate P deficiency.
