C4 photosynthesis in terrestrial plants does not require Kranz anatomy
Trends in Plant Science, 2002C(4) photosynthesis in terrestrial plants was thought to require Kranz anatomy because the cell wall between mesophyll and bundle sheath cells restricts leakage of CO(2). Recent work with the central Asian chenopods Borszczowia aralocaspica and Bienertia cycloptera show that C(4) photosynthesis functions efficiently in individual cells containing both ...

Rhynchospora rubra was found to have a low CO2 compensation point, high δ13C value, Kranz leaf anatomy, starch present in the bundle sheath cells and narrow interveinal distance. These observations suggest thatR. rubra is a C4 plant. A further anatomical survey revealed seven otherRhynchospora species presumably having the C4 photosynthetic pathway. In

Eleocharis vivipara Link is a unique amphibious leafless plant of the Cyperaceae. The terrestrial form develops culms with Kranz anatomy and C4-like traits, while the submerged form does culms with non-Kranz anatomy and C3 traits. The submerged form develops new culms with C4-like mode when exposed to air or exogenous abscisic acid.

Kranz anatomy is not essential for terrestrial C4 plant photosynthesis
Nature, 2001An important adaptation to CO2-limited photosynthesis in cyanobacteria, algae and some plants was development of CO2-concentrating mechanisms (CCM). Evolution of a CCM occurred many times in flowering plants, beginning at least 15-20 million years ago, in response to atmospheric CO2 reduction, climate change, geological trends, and evolutionary ...

Diversity of Kranz anatomy and biochemistry in C4 eudicots
American Journal of Botany, 2007C4 photosynthesis and Kranz anatomy occur in 16 eudicot families, a striking example of convergent evolution. Biochemical subtyping for 13 previously undiagnosed C4 eudicot species indicated that 10 were NADP‐malic enzyme (ME) and three were NAD‐ME. A total of 33 C4 species, encompassing four Kranz anatomical types (atriplicoid, kochioid, salsoloid ...

A Fossil Grass (Gramineae: Chloridoideae) from the Miocene with Kranz Anatomy
Science, 1986A fossil leaf fragment collected from the Ogallala Formation of northwestern Kansas exhibits features found in taxa of the modern grass subfamily Chloridoideae. These include bullet-shaped, bicellular microhairs, dumbbell-shaped silica bodies, cross-shaped suberin cells, papillae, stomata with low dome- to triangular-shaped subsidiary ...

Scarecrow Plays a Role in Establishing Kranz Anatomy in Maize Leaves
Plant and Cell Physiology, 2012More than a quarter of the primary productivity on land, and a large fraction of the food that humans consume, is contributed by plants that fix atmospheric CO(2) by C(4) photosynthesis. It has been estimated that transferring the C(4) pathway to C(3) crops could boost yield by 50% and also increase water use efficiency and reduce the need for ...

Induction of Kranz Anatomy and C4-like Biochemical Characteristics in a Submerged Amphibious Plant by Abscisic Acid [PDF]
Plant Cell, 1998 The amphibious leafless sedge Eleocharis vivipara develops C4-like traits as well as Kranz anatomy under terrestrial conditions, but it develops C3-like traits without Kranz anatomy under submerged conditions. When submerged plants are exposed to aerial conditions, they rapidly produce new photosynthetic tissues with C4-like traits.

C4 photosynthesis and a unique type of Kranz anatomy inGlossocordia boswallaea (Asteraceae)
Proceedings / Indian Academy of Sciences, 1976A special form of Kranz anatomy, a single chlorenchymatous bundle sheath around a central ground tissue embedding the vascular bundles, was observed to be associated with the C4 pathway of photosynthesis inGlossocordia boswallaea, a member of Asteraceae. The chloroplasts were centripetally located in the sheath cells. During short term carbon fixation,

Ultrastructural aspects of kranz anatomy inDigitaria sanguinalis andSetaria viridis (poaceae)
Journal of Plant Biology, 1997Structural differentiation of Kranz anatomy has been investigated in leaf cross sections of two C-4 Poaceae:Digitaria sanguinalis andSetaria viridis. The study mainly focused on cellular and interfacial features of bundle sheath (BS) and mesophyll (MS) cells of the C-4 structure.
