Occurrence and evolutionary inferences about Kranz anatomy in Cyperaceae (Poales) [PDF]
Anais da Academia Brasileira de Ciências, 2015 Cyperaceae is an angiosperm family with the greatest diversity of species with Kranz anatomy. Four different types of Kranz anatomy (chlorocyperoid, eleocharoid, fimbristyloid and rhynchosporoid) have been described for this angiosperm family, and the ...

Structural basis for C4 photosynthesis without Kranz anatomy in leaves of the submerged freshwater plant Ottelia alismoides. [PDF]
Ann Bot, 2020 Abstract Background and Aims Ottelia alismoides (Hydrocharitaceae) is a freshwater macrophyte that, unusually, possesses three different CO2-concentrating mechanisms. Here we describe its leaf anatomy and chloroplast ultrastructure, how these are altered by CO2 concentration and how they may underlie ...

A new type of Kranz anatomy in Asteraceae [PDF]
Australian Journal of Botany, 2003 The anatomical structure of the leaves and stems of the 13 species of Isostigma (Asteraceae: Heliantheae) has been examined by using light microscopy. All species of Isostigma have Kranz anatomy in their leaves, containing one or more Kranz units (=KU, the unit constituted by the vascular bundle/s, the parenchyma sheath and the surrounding mesophyll ...

Screening of Mutants Related to the C4 Photosynthetic Kranz Structure in Foxtail Millet
Frontiers in Plant Science, 2018 C4 plants exhibit significantly higher photosynthetic, water and nutrient use efficiency compared with C3 plants. Kranz anatomy is associated with many C4 plants in which bundle sheath cells surround the veins and are themselves surrounded by mesophyll ...

Intraspecifíc variability in Alloteropsis semialata (R. Br.) Hitchc.
Bothalia: African Biodiversity & Conservation, 1983 Intraspecific variability in Alloteropsis semialata (R. Br.) Hitchc. is shown ultrastructurally with particular regard to the structure of the bundle sheath and the development of the dimorphic chloroplasts in both the C3 and C4 forms of this species ...

Bothalia: African Biodiversity & Conservation, 1984 13C/12C ratios are generally regarded as being very reliable indicators of C3 or C4 photosynthesis. These relative carbon isotope ratios are expressed as a negative δ 3C and fall into two distinct groups: Kranz (or C4) plants with δ between -9°/00 no and
