Redox regulation in C3 and C4 plants during climate change and its implications on food security

open access: yesFood and Energy Security, 2023
Achieving food security and sustainable food production is a major challenge for plant scientists. To accomplish this, the global food production needs not only to be remarkably boosted, but it has to be achieved under harsh environmental conditions ...

Dynamic changes of genome sizes and gradual gain of cell‐specific distribution of C4 enzymes during C4 evolution in genus Flaveria

open access: yesThe Plant Genome, 2021
C4 plants are believed to have evolved from C3 plants through various C3–C4 intermediate stages in which a photorespiration‐dependent CO2 concentration system known as C2 photosynthesis operates.

Differential regulation of reactive oxygen species in dimorphic chloroplasts of single cell C4 plant Bienertia sinuspersici during drought and salt stress

open access: yesFrontiers in Plant Science, 2023
Single cell C4 (SCC4) plants, discovered around two decades ago, are promising materials for efforts for genetic engineering of C4 photosynthesis into C3 crops.

The Diversification of Downy Mildew Species Was Not Driven by the Loss of Mycorrhizal Associations or the Evolution of C4 Photosynthesis

open access: yesPhytoFrontiers, 2022
There are approximately 700 obligate biotrophic species grouped into 20 genera (Oomycota, Peronosporaceae) that cause downy mildew diseases. In 2001, Dick hypothesized that diversification of downy mildew species was driven in part by host plant ...

What Matters for C4 Transporters: Evolutionary Changes of Phosphoenolpyruvate Transporter for C4 Photosynthesis

open access: yesFrontiers in Plant Science, 2020
C4 photosynthesis is a complex trait that evolved from its ancestral C3 photosynthesis by recruiting pre-existing genes. These co-opted genes were changed in many aspects compared to their counterparts in C3 species.

A Model of C4 Photosynthetic Acclimation Based on Least‐Cost Optimality Theory Suitable for Earth System Model Incorporation

open access: yesJournal of Advances in Modeling Earth Systems, 2022
Empirical studies have shown that plant photosynthetic responses to environmental change can vary over time due to acclimation, but acclimation responses are often not included in Earth System Models.

Ecophysiological traits of grasses: resolving the effects of photosynthetic pathway and phylogeny [PDF]

open access: yes, 2009
C4 photosynthesis is an important example of convergent evolution in plants, having arisen in eudicots, monocots and diatoms. Comparisons between such diverse groups are confounded by phylogenetic and ecological differences, so that only broad ...

Understanding Maize Response to Nitrogen Limitation in Different Light Conditions for the Improvement of Photosynthesis

open access: yesPlants, 2021
The photosynthetic capacity of leaves is determined by their content of nitrogen (N). Nitrogen involved in photosynthesis is divided between soluble proteins and thylakoid membrane proteins.

The role of photorespiration during the evolution of C4 photosynthesis in the genus Flaveria

open access: yeseLife, 2014
C4 photosynthesis represents a most remarkable case of convergent evolution of a complex trait, which includes the reprogramming of the expression patterns of thousands of genes.

Small-molecule inhibition of pyruvate phosphate dikinase targeting the nucleotide binding site. [PDF]

open access: yesPLoS ONE, 2017
Pyruvate phosphate dikinase (PPDK) is an essential enzyme of C4 photosynthesis in plants, catalyzing the ATP-driven conversion of pyruvate to phosphoenolpyruvate (PEP).
