Genome-wide identification of SHMT family genes in C3, C3-C4, and C4 Salsoleae s.l. species [PDF]
C4 photosynthesis is a carbon-concentrating mechanism that evolved to enhance photosynthetic efficiency under conditions favoring photorespiration, such as high temperature, low atmospheric CO2, and aridity.

Biochar addition can negatively affect plant community performance when altering soil properties in saline-alkali wetlands [PDF]
Biochar is a widely proposed solution for improving degraded soil in coastal wetland ecosystems. However, the impacts of biochar addition on the soil and plant communities in the wetland remains largely unknown.

Antisense reduction in NADP-ME in the C<sub>4</sub> species Flaveria bidentis alters stomatal sensitivity to intercellular [CO<sub>2</sub>]. [PDF]
Summary Stomata have the crucial role of balancing the uptake of CO2 for photosynthesis and water loss via transpiration by adjusting their aperture. In C3 plants, coordination between photosynthesis and stomatal conductance can be disrupted by mutations in Calvin–Benson–Bassham (CBB) cycle expression, but it is not clear whether the disruption of the ...

Conserved spatial patterning of gene expression in independent lineages of C<sub>4</sub> plants. [PDF]
Summary C4 photosynthesis enhances carbon fixation efficiency by reducing photorespiration through the use of an oxygen‐insensitive carboxylase and spatial separation of photosynthesis between mesophyll and bundle sheath cells. The C4 pathway has evolved independently in > 60 plant lineages, but molecular mechanisms underpinning this convergence remain

Improved mesophyll-bundle sheath connectivity is achieved via different mechanisms in C<sub>2</sub> vs C<sub>4</sub> Alternanthera. [PDF]
Leaf anatomy and biochemistry of C3, C2, and C4 plants. Summary Connectivity between mesophyll (M) and bundle sheath (BS) cells must improve during the evolution of C4 photosynthesis to facilitate large metabolite fluxes between these cell types, but the trait combinations that enhance M–BS connectivity and the points at which these enhancements occur ...

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.

How evolution repeatedly builds complexity: a case study with C<sub>4</sub> photosynthesis in Blepharis (Acanthaceae). [PDF]
Summary With over 60 parallel origins representing evolutionary replicates, C4 photosynthesis is well‐suited for studying complex trait evolution. However, lineages with diverse C3–C4 intermediate species are scarce, leaving uncertainty in models of C4 evolution.

Systemic and Local Regulation of Root Growth by Vascular Trehalose 6-Phosphate is Correlated With Re-allocation of Primary Metabolites Between Shoots and Roots. [PDF]
ABSTRACT Trehalose 6‐phoshpate (Tre6P) is a key signalling molecule that reflects carbon status and integrates it with developmental decision making. Tre6P has been demonstrated to regulate various developmental processes, including vegetative growth, shoot branching, flowering, and root branching.

The coordination of major events in C4 photosynthesis evolution in the genus Flaveria
C4 photosynthesis is a remarkable complex trait, elucidations of the evolutionary trajectory of C4 photosynthesis from its ancestral C3 pathway can help us better understand the generic principles of the evolution of complex traits and guide the ...
