To better understand the mechanisms of plant tolerance to high concentration of arsenic, we characterized two antioxidant enzymes, glutathione reductase (GR) and catalase (CAT), in the fronds of Pteris vittata, an arsenic-hyperaccumulating fern, and Pteris ensiformis, an arsenic-sensitive fern. The induction, activation and apparent kinetics of GR and CAT in the plants upon arsenic exposure wer...

In Morocco, extensive use, traditional practices, and climate change have seriously impacted the productivity of aromatic medicinal plants (AMP). To mitigate these adverse effects, this study aims at evaluating potential arbuscular mycorrhizal fungi (AMF), namely Rhizophagusirregularis Funneliformis mosseae, in improving biomass, essential oils (EOs), biomolecule production Thymus satureioides,...

To investigate the molecular changes underlying kindling epileptogenesis in the rat hippocampus, the expression levels of the genes encoding for 13 different gamma-aminobutyric acid type-A receptor (GABAAR) subunits were measured in hippocampal principal neurons using in situ hybridization techniques and semi-quantitative analysis of the autoradiograms. Schaffer collateral-commissural pathway k...

Ixeris dentata (Thunb. ex Thunb.) Nakai (family Asteraceae) a plant widely distributed in Viet Nam, is perennial herb that grows to height of 0.5 m. It has been used as medicinal medicine since ancient times for the treatment calculi, dyspepsia, indigestion, pneumonia, hepatitis, contusion, and tumors Northeast Asia. The biological activities this have shown be neuroprotective, anti-mutagenic, ...

Safe incineration of harvested hyperaccumulators containing high content of heavy metals to avoid secondary environmental pollution is a problem for popularizing phytoremediation technology. The As volatilization behavior and its mechanism during incineration of Pteris vittata, an As-hyperaccumulator, was investigated. Incineration results reveal that 24% of total As accumulated by P. vittata (...

A new species Coomaniella (Coomaniella) dentata sp. nov. from Guangxi Province, China, is described and placed in the C. (C.) chinensis species-group. The variability discussed, a adult host plant recorded. New distributional records are given for biformissima Jendek & Kalashian, 1999 lingafelteri Pham, 2013.
