Genetic transformation of the C₄ plant, Flaveria bidentis [PDF]

The Plant Journal, 1994
SummaryAn efficient and rapid transformation system for the dicotyledonous C4 plant, Flaveria bidentis has been developed. The method involves Agrobacterium tumefaciens infection of explants followed by regeneration of shoots from kanamycin‐resistant callus.

Transcriptome dynamics in developing leaves from C3 and C4 Flaveria species

The Plant Journal, Volume 120, Issue 4, Page 1438-1456, November 2024.
SUMMARY C4 species have evolved more than 60 times independently from C3 ancestors. This multiple and parallel evolution of the complex C4 trait suggests common underlying evolutionary mechanisms, which could be identified by comparative analysis of closely related C3 and C4 species.

Identification of the amino acid residues responsible for cold tolerance in Flaveria brownii pyruvate,orthophosphate dikinase [PDF]

, 1996
Pyruvate,orthophosphate dikinase (PPDK), an enzyme important in C4 photosynthesis, is typically a cold-sensitive enzyme. However, a cold-tolerant form of the enzyme has been isolated from the leaves of Flaveria brownii.

Chloroplast NADH dehydrogenase‐like complex‐mediated cyclic electron flow is the main electron transport route in C4 bundle sheath cells

New Phytologist, Volume 243, Issue 6, Page 2187-2200, September 2024.
Summary The superior productivity of C4 plants is achieved via a metabolic C4 cycle which acts as a CO2 pump across mesophyll and bundle sheath (BS) cells and requires an additional input of energy in the form of ATP. The importance of chloroplast NADH dehydrogenase‐like complex (NDH) operating cyclic electron flow (CEF) around Photosystem I (PSI) for ...

C4 monocots and C4 dicots exhibit rapid photosynthetic induction response in contrast to C3 plants

Physiologia Plantarum, Volume 176, Issue 4, July/August 2024.
Abstract Considering the prevalence of ever‐changing conditions in the natural world, investigation of photosynthetic responses in C4 plants under fluctuating light is needed. Here, we studied the effect of dynamic illumination on photosynthesis in totally 10 C3, C3–C4 intermediate, C4‐like and C4 dicots and monocots at CO2 concentrations of 400 and ...

The operation of PEPCK increases light harvesting plasticity in C4 NAD–ME and NADP–ME photosynthetic subtypes: A theoretical study

Plant, Cell &Environment, Volume 47, Issue 6, Page 2288-2309, June 2024.
Abstract The repeated emergence of NADP–malic enzyme (ME), NAD–ME and phosphoenolpyruvate carboxykinase (PEPCK) subtypes of C4 photosynthesis are iconic examples of convergent evolution, which suggests that these biochemistries do not randomly assemble, but are instead specific adaptations resulting from unknown evolutionary drivers.

A MEM1-like motif directs mesophyll cell-specific expression of the gene encoding the C4 carbonic anhydrase in Flaveria [PDF]

, 2020
The first two reactions of C4 photosynthesis are catalysed by carbonic anhydrase (CA) and phosphoenolpyruvate carboxylase (PEPC) in the leaf mesophyll (M) cell cytosol.

A K homology (KH) domain protein identified by a forward genetic screen affects bundle sheath anatomy in Arabidopsis thaliana

Plant Direct, Volume 8, Issue 4, April 2024.
Abstract Because of their photosynthetic capacity, leaves function as solar panels providing the basis for the growth of the entire plant. Although the molecular mechanisms of leaf development have been well studied in model dicot and monocot species, a lot of information is still needed about the interplay of the genes that regulate cell division and ...

Carbonic Anhydrase and Its Influence on Carbon Isotope Discrimination during C4 Photosynthesis. Insights from Antisense RNA in Flaveria bidentis

, 2015
In C4 plants, carbonic anhydrase (CA) facilitates both the chemical and isotopic equilibration of atmospheric CO2 and bicarbonate (HCO3-) in the mesophyll cytoplasm.

Molecular comparison of carbonic anhydrase from Flaveria species demonstrating different photosynthetic pathways.

, 1995
During the evolution of C4 plants from C3 plants, both the function and intracellular location of carbonic anhydrase (CA) have changed. To determine whether these changes are due to changes at the molecular level, we have studied the cDNA sequences and ...
