C(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 the C(4) and C(3) cycles. These discoveries...
The weedy species Parthenium hysterophorus (Asteraceae) possesses a Kranz-like leaf anatomy. The bundle sheath cells are thick-walled and contain numerous granal chloroplasts, prominent mitochondria, and peroxisomes, all largely arranged in a centripetal position. Both mesophyll and bundle sheath chloroplasts accumulate starch. P. hysterophorus exhibits reduced photorespiration as indicated by ...
C(4) photosynthesis outperforms the ancestral C(3) state in a wide range of natural and agro-ecosystems by affording higher water-use and nitrogen-use efficiencies. It therefore represents a prime target for engineering novel, high-yielding crops by introducing the trait into C(3) backgrounds. However, the genetic architecture of C(4) photosynthesis remains largely unknown. To define the diverg...
In Brazil, Froelichia tomentosa (Mart.) Moq. has records of occurrence in Rio Grande do Sul (RS) and Bahia, however, the former there are indications that its populations extinct. RS, restricted to region sandy- fields. this region, biodiversity been threatened by advances agriculture forestry intensified sandy patch process. Therefore, work aimed describe morphoanatomy ultrastructure leaf blad...
Abstract This invited Team Profile was created by the Collaborative Research Center for Light-Driven Catalysis in Soft Matter, CataLight, located at Friedrich Schiller University Jena, Ulm University, Max Planck Institute of Polymer (MPI) and Johannes Gutenberg Mainz, Vienna, Electron Microscopy, University. The authors, who include members Kranz Leopold Groups, Schacher Group, Streb recently p...
