Evolution of C4 photosynthesis predicted by constraint-based modelling

eLife, 2019
Constraint-based modelling (CBM) is a powerful tool for the analysis of evolutionary trajectories. Evolution, especially evolution in the distant past, is not easily accessible to laboratory experimentation.

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 ...

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.

Environmental influences on the maximum quantum yield of terrestrial primary production

New Phytologist, EarlyView.
Temperature and aridity effects on terrestrial ecosystems' intrinsic quantum yield. Summary Historically, terrestrial biosphere models (TBMs) have assigned the intrinsic (maximum) quantum yield of photosynthesis (ϕ0)$$ {\phi}_0\Big) $$ a constant value for each plant functional type. However, experimental studies have shown that ϕ0$$ {\phi}_0 $$ – when

The genetic architecture of leaf vein density and its importance for photosynthesis in maize

New Phytologist, EarlyView.
Vein types in maize leaves. Summary Leaf venation density has significantly increased during plant evolution. Higher densities are observed in angiosperms compared with early land plants, and among angiosperms, recently diverged C4 species have the highest values.

Revisiting the Molecular Roadmap for Sugar Crops: Genome Reading, Trait Writing and Variety Redesigning

Plant Biotechnology Journal, EarlyView.
ABSTRACT Sugar crops, including but not limited to sugarcane, sugar beet, sweet sorghum and stevia, are major sources of sugar production in the world. However, conventional breeding approaches, limited by long breeding cycles, low efficiency and restricted capacity to improve complex traits in sugar crops, are increasingly insufficient to address the ...

MYB Factors: Hubs of Plant Stress and Hormone Crosstalk

Plant Biotechnology Journal, EarlyView.
ABSTRACT MYB transcription factors function as main regulatory hubs that integrate environmental signals with multi‐hormonal pathways to synchronize plant growth, metabolism and stress responses. This review delineates the regulatory roles of MYB in the signalling pathway of salicylic acid, jasmonic acid, ethylene and abscisic acid signalling.

Concurrent Measurement of O2 Production and Isoprene Emission During Photosynthesis: Pros, Cons and Metabolic Implications of Responses to Light, CO2 and Temperature

Plant, Cell &Environment, EarlyView.
ABSTRACT Traditional leaf gas exchange experiments have focused on net CO2 exchange (Anet). Here, using California poplar (Populus trichocarpa), we coupled measurements of net oxygen production (NOP), isoprene emissions and δ18O in O2 to traditional CO2/H2O gas exchange with chlorophyll fluorescence, and measured light, CO2 and temperature response ...

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

Plant, Cell &Environment, EarlyView.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.
