[C4 type photosynthesis].

open access: yesPostepy biochemii, 2012
C4 photosynthesis includes several anatomical and biochemical modifications that allow plants to concentrate CO2 at the site of Rubisco. The photorespiratory pathway is repressed in C4 plants, since the rates of photosynthesis and biomass production are increased. This is an adaptation to high light intensities, high temperatures and dryness. C4 plants

Evidence for regulation of transpiration in nonstomatal plants: insights from bryophyte gametophytes

open access: yesNew 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 ...

Using Evolution as a Guide to Engineer Kranz-Type C4 photosynthesis

open access: yesFrontiers in Plant Science, 2013
Kranz-type C4 photosynthesis has independently and rapidly evolved over sixty times to dramatically increase radiation use efficiency in both monocots and eudicots. Indeed, it is one of the most exceptional examples of convergent evolution in the history

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

open access: yesNew 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

Kinetic parameter prediction using neural networks identifies limitations to C4 photosynthesis

open access: yesNew 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

open access: yesNew 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

open access: yesNew 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.

Molecular investigation of how drought stress affects chlorophyll metabolism and photosynthesis in leaves of C3 and C4 plant species: A transcriptome meta-analysis

open access: yesHeliyon
Drought stress has a significant impact on photosynthesis in plants, leading to reduced photosynthesis rates and affecting plant growth and yield. Understanding the effects of drought stress on photosynthetic pathways, particularly in C3 and C4 plants ...
