Reactive oxygen species (ROS) arise in the plant system due to inevitable influence of various environmental stimuli. Glutathione peroxidases are one of the important ROS scavengers inside the cell. A glutathione peroxidase (PgGPx) gene was previously found from Pennisetum glauccum abiotic stressed
Glutathione reductase a unique enzyme: molecular cloning, expression and biochemical characterization from the stress adapted C4 plant, Pennisetum glaucum (L.) R. Br.

The generation of excess reactive oxygen species (ROS) is one of the most common consequences of abiotic stress on plants. Glutathione reductase (GR, E.C. 1.6.4.2) and allied enzymes of the ascorbate-glutathione cycle play a crucial role to maintain the homeostatic redox balance in the cellular

OBJECTIVE
It has been shown that alcohol impairs erythrocyte (red blood cell) membrane fluidity and lipid composition. The aim of this study was to test the effect of a novel acid-resistant antioxidant on the hemorrheology in alcoholics.
METHODS
Thirty alcoholics (25 males, 5 females; mean age: 42

CONCLUSIONS
PgDHAR was isolated from Pennisetum glaucum. PgDHAR responded to abiotic stress and exhibited enzyme activity at broad ranges of temperature, pH and substrate concentrations suggesting its role in stress tolerance.
UNASSIGNED
Dehydroascorbate reductase (EC 1.8.5.1) is a crucial enzyme
Non-native ligands define the active site of Pennisetum glaucum (L.) R. Br dehydroascorbate reductase.

Dehydroascorbate reductase (DHAR), a member of the glutathione-S-transferase (GST) family, reduces dehydroascorbate (DHA) to ascorbate (AsA; Vitamin-C) in a glutathione (GSH)-dependent manner and in doing so, replenishes the critical AsA pool of the cell. To understand the enzyme mechanism in

: A rapid and continuous growth of silver nanoparticles (AgNPs) via their precursor "silver nitrate" (AgNO3) has increased their environmental risk because of their unsafe discharge into the surrounding environment. Both have damaging effects on plants and induce

This research presented here, for the first time, elucidates the responses of several antioxidants in Pennisetum leaves exposed to varying concentrations of atrazine (0 - 200 mg•kg-1). Pennisetum has been reported to be resistant to atrazine; however, its physiological response to high

OBJECTIVE
The objective of the present study was to investigate the lipid and the antioxidant regulatory potential of a multigrain diet in laboratory animals with reference to lipid profiles, tissue lipid peroxidation and antioxidant status.
METHODS
Two types of diets, with or without addition of

King grass, a hybrid grass between pearl millet and elephant grass, has many excellent characteristics such as high biomass yield, great stress tolerance, and enormous economic and ecological value, which makes it ideal for development of phytoremediation. At present, the physiological and molecular

Pearl millet (Pennisetum glaucum) is the sixth-leading cereal crop and a staple food crop. It is known for its high tolerance to abiotic stress and good nutrient profile. NAC (NAM, ATAF1/2 and CUC) transcription factors (TFs) play an important role in abiotic stress tolerance. In our study, the
Exogenous calcium induces tolerance to atrazine stress in Pennisetum seedlings and promotes photosynthetic activity, antioxidant enzymes and psbA gene transcripts.

Calcium (Ca) has been reported to lessen oxidative damages in plants by upregulating the activities of antioxidant enzymes. However, atrazine mediated reactive oxygen species (ROS) reduction by Ca is limited. This study therefore investigated the effect of exogenously applied Ca on ROS, antioxidants
