Kranz anatomy, with its separation of elements of the C4 pathway between two cells, has been an accepted criterion for function of C4 photosynthesis in terrestrial plants. However, Bienertia cycloptera (Chenopodiaceae), which grows in salty depressions of Central Asian semi-deserts, has unusual chlorenchyma, lacks Kranz anatomy, but has photosynthetic features of C4 plants. Its photosynthetic response to varying CO2 and O2 is typical of C4 plants having Kranz anatomy. Lack of night-time CO2…

Functional compartmentation of C4 photosynthesis in the triple layered chlorenchyma of Aristida (Poaceae).

The results indicate that mesophyll cells contain high levels of phosphoenolpyruvate carboxylase (PEPC) and pyruVate Pi dikinase (PPDK), and function to capture CO2 in the C4 cycle.

Resolving the Compartmentation and Function of C4 Photosynthesis in the Single-Cell C4 Species Bienertia sinuspersici1[OA]

Functional characterization by photosynthetic oxygen evolution revealed that only the C-CP have a fully operational C3 cycle, while both chloroplast types have the capacity to photoreduce 3-phosphoglycerate, and the implications for the energetics of the C4 and C3 cycles are discussed.

Differentiation of cellular and biochemical features of the single-cell C4 syndrome during leaf development in Bienertia cycloptera (Chenopodiaceae).

This form of single-cell C(4) photosynthesis develops from a common pool of organelles through partitioning to separate compartments, and the development of biochemically and ultrastructurally dimorphic chloroplasts.

The Cytoskeleton Maintains Organelle Partitioning Required for Single-Cell C4 Photosynthesis in Chenopodiaceae Species[W]

Compartmentalization of the organelles in these species represents a unique system in higher plants and illustrates the degree of control the plant cell has over the organization and integration of multiorganellar processes within its cytoplasm.

Recent progress in the single-cell C4 photosynthesis in terrestrial plants

This review focuses on the recent progress in understanding the cellular and molecular mechanisms that control the spatial relationship of organelles in these unique single-cell C4 systems.

Structural basis for C4 photosynthesis without Kranz anatomy in leaves of the submerged freshwater plant Ottelia alismoides.

There is sufficient structural diversity within the leaf of O. alismoides to support dual-cell C4 photosynthesis even though Kranz anatomy is absent, and this suggests they may benefit from an internal source of CO2, for example via C4 metabolism, and are also sites of starch storage.

Chapter 4 C4 Photosynthesis: Kranz Forms and Single-Cell C4 in Terrestrial Plants

In this chapter, biochemical and structural variations of Kranz anatomy in three major C4-containing families, Poaceae, Cyperaceae, and Chenopodiaceae, as well as other known forms for dicots, are summarized.

Exploring mechanisms linked to differentiation and function of dimorphic chloroplasts in the single cell C4 species Bienertia sinuspersici

Both CCC RLSB localization and the differential chloroplast redox state are suggested to have a role in post-transcriptional rbcL expression.

Does Bienertia cycloptera with the single-cell system of C4 photosynthesis exhibit a seasonal pattern of δ13C values in nature similar to co-existing C4 Chenopodiaceae having the dual-cell (Kranz) system?

The measurements of δ13C values over a complete growing season show that B. cycloptera performs C4 photosynthesis during its life cycle in nature, similar to Kranz type species, with a seasonal average δ 13C value of −15.2‰.

Species Having C4 Single-Cell-Type Photosynthesis in the Chenopodiaceae Family Evolved a Photosynthetic Phosphoenolpyruvate Carboxylase Like That of Kranz-Type C4 Species1

It was found that PEPC from both types of C4 chenopods displays higher specific activity than that of the C3 species and shows kinetic and regulatory characteristics similar to those of C 4 species in other families in that they are subject to light/dark regulation by phosphorylation and display differential malate sensitivity.




A hypothesis is presented stating that the uniquie morphological and biochemical characters of these plants represent adaptations for efficient and rapid carbon fixation in environments where water stress frequiently limits photosynthesis.

The hypothesis is developed that in species or groups of taxa specific leakages of their C4 systems do occur and this corresponds well with the variance in data from different individuals and populations.

Kranz anatomy is not essential for terrestrial C4 plant photosynthesis

Evidence that C4 photosynthesis can function within a single photosynthetic cell in terrestrial plants is provided and it is shown that Borszczowia aralocaspica (Chenopodiaceae) has the photosynthesis features of C4 plants, yet lacks Kranz anatomy.

A remarkable new leaf type with unusual photosynthetic tissue in a central Asiatic genus of Chenopodiaceae.

A new leaf type with 1-layered chlorenchyma is described as “borszczovoid” and compared with other leaf types in subfamily Salsoloideae and a13C values are given for the first time from eight species of Chenopodiaceae.

Distribution of photorespiratory enzymes between bundle-sheath and mesophyll cells in leaves of the C3−C4 intermediate species Moricandia arvensis (L.) DC

It is suggested that glycine produced by photorespiratory metabolism in the mesophyll is decarboxylated predominantly by the mitochondria in the bundle sheath, which is considerably higher on a mitochondrial basis in bundle-sheath than in Mesophyll cells.

Occurrence of C3 and C4 photosynthesis in cotyledons and leaves of Salsola species (Chenopodiaceae)

Differences in photosynthetic types of leaves and cotyledons may be used as a basis or studies of the origin and evolution of C4 photosynthesis in the family Chenopodiaceae are suggested.

Cloning and analysis of the C4 photosynthetic NAD-dependent malic enzyme of amaranth mitochondria.

Glycine decarboxylase is confined to the bundle-sheath cells of leaves of C3−C4 intermediate species

Confinement of glycine decarboxylase to the bundle-sheath cells is likely to improve the potential for recapture ofPhotorespired CO2 via the Calvin cycle and could account for the low rate of photorespiration in all C3−C4 intermediate species.

What Does It Take to Be C 4 ? Lessons from the Evolution of C 4 Photosynthesis

Twenty-five years ago research had already established a firm biochemical and physiological understanding of the CO2-concentrating mechanism that creates a high CO2 environment (1,000‐3,000 mbar) in

Anatomy, chloroplast structure and compartmentation of enzymes relative to photosynthetic mechanisms in leaves and cotyledons of species in the tribe salsoleae (Chenopodiaceae)

In non-Kranz cotyledons of Halocharis gossypina and Haloxylon persicum, Rubisco was found in chloroplasts of both palisade and spongy mesophyll cells with the heaviest labelling in the layers ofPalisade cells, whereas C 4 pathway proteins were low or undetectable.
