Single-cell C(4) photosynthesis versus the dual-cell (Kranz) paradigm.
The amazing diversity in C( 4) systems is discussed, how the essential features of C(4) are accomplished in single-cell versus Kranz-type C(2) plants, and speculates on why single- cell C(3) plants evolved. Expand
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. Expand
Coordination of Leaf Photosynthesis, Transpiration, and Structural Traits in Rice and Wild Relatives (Genus Oryza)1[W][OA]
High gm together with high gm/gs and a low Smes/gm ratio appear to be ideal for supporting leaf photosynthesis while preserving water; in addition, thick M cell walls may be beneficial for plant drought tolerance. Expand

Diversity in leaf anatomy, and stomatal distribution and conductance, between salt marsh and freshwater species in the C(4) genus Spartina (Poaceae).
Differences in structural-functional features of photosynthesis in Spartina species are suggested to be related to adaptations to saline environments. Expand

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. Expand
Salsola arbusculiformis, a C3–C4Intermediate in Salsoleae (Chenopodiaceae)
Measurements of its CO2 compensation point and CO2 response of photosynthesis show S. arbusculiformis functions as an intermediate species with reduced levels of photorespiration, and analysis of photosynthetic enzymes (activity and immunolocalization) and 14 CO2 labelling of initial fixation products suggests minimal operation of a C4 cycle. Expand
Proof of C4 photosynthesis without Kranz anatomy in Bienertia cycloptera (Chenopodiaceae).
The results show Bienertia utilizes strict compartmentation of organelles and enzymes within a single cell to effectively mimic the spatial separation of Kranz anatomy, allowing it to function as a C4 plant having suppressed photorespiration; this raises interesting questions about evolution of C4 mechanisms. Expand
Physiological, anatomical and biochemical characterisation of photosynthetic types in genus Cleome (Cleomaceae).
From screening more than 230 samples of Cleomaceae species, based on a measure of the carbon isotope composition (δ13C) in leaves, it is indicated that this is an interesting family for studying the genetic basis for C4 photosynthesis and its evolution from C3 species. Expand
