Soil phosphorus drives subcontinental patterns of carbon isotope discrimination across Australia

New Phytologist, EarlyView.
Summary Several transects have been established to study the sensitivity of carbon isotope discrimination (Δ13C) in woody plants to mean annual precipitation (MAP) across Australia. These have shown a surprising divergence in Δ13C‐MAP sensitivity among subcontinental regions.

Fire Blight Management: Physiological Assessment of Cultural Control By Pruning in Pear Orchards

Agriculture, 2020
The aim of this work was to evaluate the photosynthetic performance of Pear trees (cv. ‘Rocha’) infected with Erwinia amylovora, three months after suffering a pruning of infected branches (P-trees) compared with asymptomatic trees (C-trees) of the same ...

Heat Denaturation Profiles of Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase (Rubisco) and Rubisco Activase and the Inability of Rubisco Activase to Restore Activity of Heat-Denatured Rubisco

Plant Physiology, 1997
Abstract We compared the heat-denaturation profiles of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) and Rubisco activase and further examined the ability of Rubisco activase to restore the activity of heat-denatured Rubisco originally reported (E. Sanchez de Jimenez, L. Medrano, and E. Martinez-Barajas [1995] Biochemistry 34:

Climate change and crop resilience: harnessing metabolomics for predicting stress tolerance

New Phytologist, EarlyView.
Summarised methodology for metabolite biomarker discovery and genomic targets selection for those metabolites to predict high‐throughput phenotypic and agronomic traits of interest for direct uptake in breeding programmes. Summary Global warming is driving climate change to levels not experienced since the advent of agriculture, primarily due to ...

Rapid dehydration drives a nondiffusional drop in C3 photosynthesis that aligns with phosphate limitation

New Phytologist, EarlyView.
Schematic representation of the causal sequence through which rapid water loss imposes diffusive and nondiffusive restrictions on carbon assimilation. Summary Drought is an abnormally prolonged water deficit posing major challenges to plants. Stomatal closure has long been considered the primary factor limiting photosynthesis during the early stages of

Influence of vapour pressure deficit and CO2 on the thermal sensitivity of stomatal function in tropical trees

New Phytologist, EarlyView.
Examining the potential thermal sensitivity of the model parameter g1 when accounting for the additive nature of underlying components including CO2 compensation point (Г*) and the marginal water cost of plant carbon gain (λ), when assuming λ is dependent upon changes in the viscosity (inverse of fluidity) of water (η, Pa·s) and the solubility of CO2 ...

Discoveries in Rubisco (Ribulose 1,5-bisphosphate carboxylase/oxygenase) : a historical perspective

, 2007
Historic discoveries and key observations related to Rubisco (Ribulose 1,5-bisphosphate carboxylase/oxygenase), from 1947 to 2006, are presented. Currently, around 200 papers describing Rubisco research are published each year and the literature contains

Kinetic parameter prediction using neural networks identifies limitations to C4 photosynthesis

New Phytologist, EarlyView.
Schematic overview of the generation of artificial training data and training of neural networks in C4TUNE. Summary Kinetic models of photosynthesis enable time‐resolved predictions of traits related to this key process and provide the means to identify factors limiting photosynthesis.

Endogenous RALF peptide function is required for powdery mildew host colonization

New Phytologist, EarlyView.
Model of RALF‐FER‐dependent effects on powdery mildew sporulation. Summary The receptor kinase FERONIA (FER) is a susceptibility factor for biotrophic powdery mildew fungal pathogens in Arabidopsis thaliana, but the underlying molecular mechanisms remain largely unknown. FER is required for the perception of endogenous RAPID ALKALINIZATION FACTOR (RALF)

Loss of decreased-rubisco phenotype between generations of wheat transformed with antisense and sense rbcS

, 2004
The elite UK winter wheat cv. Riband was transformed with constructs containing rbcS in sense and antisense orientations driven by the maize ubiquitin promoter with a transformation efficiency of 1.2%.
