Photosynthetic Plasticity in Flaveria brownii [PDF]

Plant Physiology, 1989
Photosynthesis was examined in leaves of Flaveria brownii A. M. Powell, grown under either 14% or 100% full sunlight. In leaves of high light grown plants, the CO(2) compensation point and the inhibition of photosynthesis by 21% O(2) were significantly lower, while activities of ribulose 1,5-bisphosphate carboxylase/oxygenase and various C(4) cycle ...

Kinetic Modifications of C4 PEPC Are Qualitatively Convergent, but Larger in Panicum Than in Flaveria

Frontiers in Plant Science, 2020
C4 photosynthesis results from a set of anatomical features and biochemical components that act together to concentrate CO2 within the leaf and boost productivity.

The inevitability of C4 photosynthesis

eLife, 2014
Elements of C4 photosynthesis—a complex adaptation that increases photosynthetic efficiency—may have evolved first to correct an intercellular nitrogen imbalance, and only later evolved a central role in carbon fixation.

Nitrogen Uptake, Not Transfer of Carbon and Nitrogen by CMN, Explains the Effect of AMF on the Competitive Interactions Between Flaveria bidentis and Native Species

Frontiers in Ecology and Evolution, 2021
Rhizophagus intraradices, one of the common arbuscular mycorrhizal fungi (AMF) grown in the roots of Flaveria bidentis, facilitates the invasion of this exotic plant species into China.

Evolution of C4 Photosynthesis inFlaveria Species1 [PDF]

Plant Physiology, 1998
Abstract NADP-malic enzyme (NADP-ME, EC 1.1.1.40), a key enzyme in C4 photosynthesis, provides CO2 to the bundle-sheath chloroplasts, where it is fixed by ribulose-1,5-bisphosphate carboxylase/oxygenase. We characterized the isoform pattern of NADP-ME in different photosynthetic species ofFlaveria (C3, C3-C4intermediate, C4-like, C4 ...

Isolation and Structural Identification of Herbicidal Active Substance from Root of Flaveria bident (L.) Kuntze

Journal of Integrative Agriculture, 2014
In order to understand the composition and structure of herbicidal active substance from the root of Flaveria bidentis (L.) Kuntze, the isolation and structural identification were researched in this paper. The crude extract from the root of F. bidentis (

Photosynthetic pathway influences xylem structure and function in Flaveria (Asteraceae) [PDF]

Plant, Cell & Environment, 2008
ABSTRACTHigher water use efficiency (WUE) in C4 plants may allow for greater xylem safety because transpiration rates are reduced. To evaluate this hypothesis, stem hydraulics and anatomy were compared in 16 C3, C3–C4 intermediate, C4‐like and C4 species in the genus Flaveria. The C3 species had the highest leaf‐specific conductivity (KL) compared with

Systemic and Local Regulation of Root Growth by Vascular Trehalose 6‐Phosphate is Correlated With Re‐allocation of Primary Metabolites Between Shoots and Roots

Plant, Cell &Environment, EarlyView.
ABSTRACT Trehalose 6‐phoshpate (Tre6P) is a key signalling molecule that reflects carbon status and integrates it with developmental decision making. Tre6P has been demonstrated to regulate various developmental processes, including vegetative growth, shoot branching, flowering, and root branching.

Phylogenomics and systematics of African Sesuvium (Aizoaceae)

TAXON, Volume 75, Issue 3, June 2026.
Abstract Sesuvium (Sesuvioideae‐Aizoaceae) comprises leaf succulent annual and perennial herbs distributed in coastal or saline sites of subtropical and tropical regions. Some species of the genus tolerate highly salinized or polluted soils and show soil‐improving properties.
