All metal oxide nanoparticles influence the growth and development of plants. They generally enhance or reduce seed germination, shoot/root growth, biomass production and physiological and biochemical activities. Some plant species have not shown any physiological change, although significant variations in antioxidant enzyme activity and upregulation of heat shock protein have been observed. Pl...

†Background Aluminium (Al) toxicity is the most important soil constraint for plant growth and development in acid soils. The mechanism of Al-induced inhibition of root elongation is still not well understood, and it is a matter of debate whether the primary lesions of Al toxicity are apoplastic or symplastic. † Scope The present review focuses on the role of the apoplast in Al toxicity and res...

Aim: This study was conceived for the purpose of evaluating dermal toxicity potentials of extracts from S. glaucescens which is known for many traditional application in human and animals including healing wounds, boils, HIV, worms and application on the swollen lymph nodes of cattle suffering from east coast fever (ECF). This followed the scanty availability of information regarding Original R...

Aluminium toxicity in acid soils having pH below 5.5, affects the production of staple food crops, vegetables and cash crops worldwide. About 50% of the world’s potentially arable lands are acidic. It is trivalent cationic form i.e. Al that limits the plant’s growth. Absorbed Aluminium inhibits root elongation and adversely affects plant growth. Recently researches have been conducted to unders...

To investigate the protective effect of the leaf extract of Andrographis paniculata (Ap) against ethanol induced liver toxicity in male albino rats. The liver toxicity was induced by the administration of ethanol to the animals at the optimum dosage of 7.9g/kg body wt., orally for 45 days. After induction of liver toxicity the aqueous plant extract of A.p was administered to the animal 250 mg/k...

essential oil extracted from the leaves of myrtle, myrtus communis l. (myrtaceae)was tested in vitro for volatile toxicity against two stored-product insects (tribolium confusum and callosobruchus maculatus). the chemical composition of the plant oil was examined by gas chromatography-mass spectrometry (gc-ms). the major oil components were α-pinene (10.4%), α- terpineol (10.1%), linalool (9.0%...

INTRODUCTION Human contact with potentially toxic plants, which may occur through abuse or by accident or attempted suicide, is frequent and sometimes results in clinically significant toxicity. OBJECTIVE The aim of the present study was to identify which plants may lead to severe poisoning, and to define the clinical relevance of plant toxicity for humans in Switzerland. METHODS We analyze...

Many soils are contaminated by heavy metals, with arsenic posing serious environmental threat. Enrichment of soil with phosphate is believed to reduce the arsenic toxicity. However, only a few attempts have already been conducted towards understanding the precise role of phosphate in controlling As toxicity. Moreover, there is no adequate information on the effect of phosphate on As-induced...
