VARIATIONS IN ANATOMY, ASSOCIATIONS, AND ORIGINS OF KRANZ TISSUE

American Journal of Botany, 1975
Although the unique tissue required for C4 photosynthesis in nonsucculent plants is often described as being modified leaf parenchyma sheath, which is positioned meaningfully between the mesophyll externally and the vascular tissues internally, the actual range of locations and known associations make that concept untenable.

Hydrilla: Inducible C4-type Photosynthesis without Kranz Anatomy

1984
Submersed aquatic macrophytes (SAM) in many instances exist in a daytime habitat that is inorganic carbon-poor, especially in free CO2, but with dissolved O2 that can exceed 200% air-saturation in dense vegetation (Van et al. 1976). These conditions may severely limit growth, by restricting photosynthesis and promoting photorespiration.

Key innovations in the evolution of Kranz anatomy and C₄ vein pattern in Flaveria (Asteraceae)

American Journal of Botany, 2007
Kranz anatomy and C4 vein pattern are required for C4 biochemical functioning in C4 plants; however, the evolutionary timing of anatomical and biochemical adaptations is unknown. From the genus Flaveria, 16 species (C3, C4, intermediates [C3–C4, C4‐like]) were analyzed, novel anatomical and vein pattern characters were analyzed and key anatomical ...

Atypical foliar anatomy related to Kranz syndrome in Paspalum inaequivalve and Paspalum microstachyum (Poaceae: Panicoideae: Paniceae)

Flora: Morphology, Distribution, Functional Ecology of Plants, 2009
Abstract Paspalum L. is a large and complex genus, enclosing more than 300 species, whose boundaries and infrageneric classification are still being studied. Recent phylogenetic analyses suggest that Paspalum inaequivalve Raddi and Paspalum microstachyum J.

[Responses of stomata and Kranz anatomy of maize leaves to soil water shortages].

Ying yong sheng tai xue bao = The journal of applied ecology, 2015
Seedlings of the popular maize cultivar "Zhengdan-958" growing in pots individually were exposed to suitable soil water conditions as control, light water shortage, moderate water shortage, and severe water shortage, corresponding to soil water contents between 75%-85%, 65%-75%, 55%-65%, and 45%-55% of field water capacity, respectively.

Photosynthesis in Nontypical C4 Species C4 Cycles without Kranz Anatomy and C4 Crassulacean Acid Metabolism Transitions

2016
All plants and kinds of eukaryotic photoautotrophs use thesame basic pathway for photosynthetic CO2 fixation: the C3cycle (alternatively called photosynthetic carbon reductioncycle or Calvin and Benson cycle). In this pathway, ribulosebisphosphate carboxylase?oxygenase (RuBisCO) catalyzesthe entry of CO2 into the cycle. At ambient CO2 and O2 conditions,

Diversity of Kranz-Anatomy and Biochemical Types of CO2 Fixation in Leaves and Cotyledons Among Chenopodiaceae Family

1998
The Chenopodiaceae contains species with C3, C4 and possibly C3-C4 intermediate photosynthesis. This family has a second place in world flora in abundance of plants with C4 photosynthesis (about 350-400 species) and it displays a large diversity of biochemical mechanisms of CO2 fixation and Kranz-anatomy in mature leaves.

Single-cell resolved differentiation of pre-Kranz anatomy in maize leaf primordia

Summary Typical C 4 plants such as maize possess highly optimized Kranz-type leaf anatomy, whereby concentric wreaths of mesophyll and bundle sheath cells surround closely spaced veins.

Identification of genes involved in Kranz anatomy evolution of non-model grasses using unsupervised machine learning

Abstract Kranz syndrome is a set of leaf anatomical and functional characteristics of species using C 4 photosynthesis. The current model for the evolution of C 4 photosynthesis from a C 3 ancestor proposes a ...
