Phosphoenolpyruvate carboxylase identified as a key enzyme in erythrocytic Plasmodium falciparum carbon metabolism.

PLoS Pathogens, 2014
Phospoenolpyruvate carboxylase (PEPC) is absent from humans but encoded in the Plasmodium falciparum genome, suggesting that PEPC has a parasite-specific function. To investigate its importance in P. falciparum, we generated a pepc null mutant (D10(Δpepc)

Electrical Properties of Poly-N-Epoxypropylcarbazole/Vanadium Pentoxide Composite

Eurasian Chemico-Technological Journal, 2007
In the present work the electrical properties of poly-N-epoxypropylcarbazole (PEPC) and vanadium pentoxide (V2O5) composite have been studied. The composite was formed by mixing of PEPC solution in benzene with V2O5 powder and stirring at room ...

Effects of Citric Acid and Humic-like Substances on Yield, Enzyme Activities, and Expression of Genes Involved in Iron Uptake in Tomato Plants

Horticulturae, 2023
Iron (Fe) deficiency is a common abiotic stress on plants growing in calcareous soils where low organic matter content, high carbonate–bicarbonate concentration, and high pH precipitate Fe in unavailable forms.

Oxygen Requirement and Inhibition of C4 Photosynthesis . An Analysis of C4 Plants Deficient in the C3 and C4 Cycles [PDF]

, 1998
The basis for O2 sensitivity of C4 photosynthesis was evaluated using a C4-cycle-limited mutant of Amaranthus edulis (a phosphoenolpyruvate carboxylase-deficient mutant), and a C3-cycle-limited transformant of Flaveria bidentis (an antisense ribulose-1,5-

The SCARECROW‐LIKE transcription factor from Populus davidiana × P. bolleana simultaneously improved drought tolerance and plant growth through acetylation‐dependent mechanisms

Plant Biotechnology Journal, EarlyView.
Summary The GAI‐RGA‐and‐SCR (GRAS) family of plant‐specific transcription factors (TFs) is essential for development and stress tolerance, but their role in drought resistance and growth remains unclear. Here, we characterized the SCARECROW‐LIKE (SCL) TF PdbSCL1 from Populus davidiana × P.

Comparative proteomics analysis of root and nodule mitochondria of soybean

Plant, Cell &Environment, EarlyView.
Abstract Legumes perform symbiotic nitrogen fixation through rhizobial bacteroids housed in specialised root nodules. The biochemical process is energy‐intensive and consumes a huge carbon source to generate sufficient reducing power. To maintain the symbiosis, malate is supplied by legume nodules to bacteroids as their major carbon and energy source ...

Salt Stress Induces Differentiated Nitrogen Uptake and Antioxidant Responses in Two Contrasting Barley Landraces from MENA Region

Agronomy, 2020
The interaction between salinity and nitrogen metabolism has been investigated in two barley landraces, one tolerant (“100/1B”) and one susceptible to salinity (“Barley medenine”) from the Middle East and North Africa (MENA) region.

Boundaries of photosynthesis: adaptations of carbon fixation in extreme environments

FEBS Open Bio, Volume 15, Issue 7, Page 1028-1040, July 2025.
Photosynthesis faces challenges from environmental extremes of temperature, pH, and salinity, limiting gas diffusion, modifying membrane fluidity, and destabilizing photochemical and biochemical reactions. Photosynthetic organisms have evolved unique adaptations overcoming these stresses and maintaining their photosynthetic activity.
