To investigate responses of Glycyrrhiza glabra var. glabra and G. glabra var. glandulifera to molybdenum and salicylic acid, we measured four stress biochemical parameters: anthocyanin, nitric acid, glycyrrhizic acid and peroxidase activity in callus tissues. Callus tissues obtained from seedlings root cultures were treated by 60 mg. l-1 molybdenum and 5 µM salicylic acid alone or together for...

Plant biomass harvested after heavy-metal phytoremediation must be considered as a hazardous waste that should be contained or treated appropriately before disposal or reuse. This study provides an evaluation of extractants for the removal of lead from Abutilon Theophrastus biomass. The research was carried out a leaching study to determine the lead-extraction efficiency of the different leacha...

Salicylic acid-deficient NahG transgenic lines and sid2 mutants were used to evaluate the role of this compound in the development of the short-lived, annual plant Arabidopsis thaliana, with a particular focus on the interplay between salicylic acid and other phytohormones. Low salicylic acid levels led to increased growth, as well as to smaller abscisic acid levels and reduced damage to PSII (...

The mobility of Cu, Pb and Zn in harbour sediments was investigated using single, sequential and kinetic extraction techniques. Each type of extraction provides different information on the mobility of these elements in the environment. The single HCl extraction assesses general mobility, the sequential extraction assesses geochemical partitioning and kinetic extraction allows quickly and slowl...

Salicylic acid can mitigate the impacts of salinity and drought stresses in crops. To study the effect of salicylic acid under iso-osmotic drought and salt stresses on nutrients absorption and growth of linseed (Linum usitatissimum L.), an experiment was conducted based on a completely randomized design with three replications in Yasouj University in 2016. Treatments included salinity and droug...

In i6 workers with lead poisoning of varying degrees, a comparison was made between the therapeutic efficacy of sodium calciumedetate (Ca-EDTA) and penicillamine (PCA), administered intravenously and orally. The question of comparable dosages of ligands, forming metal complexes in different ways, is discussed. With the dosages given, intravenous Ca-EDTA promoted the greatest output of lead in t...

the study aimed to come up with a list of specific macroalgae species, which could be used to biomonitor specific metal elements in the coastal waters of east africa. water extraction, edta, aqua regia extraction and optimized bcr 3-step sequential extracts were used to mimic bioavailable metals under various environmental conditions. the results indicated that ulva lactuca could be used as a ...

The activation of programmed cell death (PCD) is often a result of complex signalling pathways whose relationship and intersection are not well understood. We recently described a PCD root hair assay and proposed that it could be used to rapidly screen genetic or pharmacological modulators of PCD. To further assess the applicability of the root hair assay for studying multiple signalling pathwa...

The study aims at assessing the physicochemical properties, heavy metals, and aflatoxins content of crude palm groundnut oils produced sold in Adikpo, Wadata, Otukpa areas Benue state, Nigeria. Specific gravity, refractive index, acid value, saponification peroxide moisture content, smoke point are properties evaluated. metals analyzed include; Lead, Nickel, Copper, Iron, Arsenic, Iron. Total w...
