BACKGROUND Herbaceous plants are common vegetal species generally exposed, for a limited period of time, to bioavailable environmental pollutants. Heavy metals contamination is the most common form of environmental pollution. Herbaceous plants have never been used as natural bioindicators of environmental pollution, in particular to monitor the amount of heavy metals in soil. In this study, we ...

A basic tenet of ecology is that negative feedback on abundance plays an important part in the coexistence of species within guilds. Mutualistic interactions generate positive feedbacks on abundance and therefore are not thought to contribute to the maintenance of diversity. Here, I report evidence of negative feedback on plant growth through changes in the composition of their mutualistic fung...

Higher plants possess medium-sized gene families that encode plasma membrane-localized sucrose transporters. For several plant species, it has been shown that at least one of these genes (e.g., AtSUC3 in Arabidopsis and LeSUT2 in tomato) differs from all other family members in several features, such as the length of the open reading frame, the number of introns, and the codon usage bias. For t...

In the presence of a warmer climate, increase comparative abundance fungal plant pathogens. Many most aggressive pathogens are soil-borne fungi. Alternaria species threaten food security as chemical fungicides currently used against them mostly ineffective because acquired resistance to active compounds. Broadleaf plantain (Plantago major L.) and rosemary (Rosmarinus officinalis extracts, obtai...

The aim of this study is to examine the peculiarities accumulation most dangerous heavy metals and arsenic in medicinal plant raw material synanthropic flora Voronezh region.
 Materials Methods. was carried out by atomic absorption spectrometry. author studied (lead, mercury, cadmium, nickel, copper, zinc, cobalt, chromium) 10 types materials harvested 51 locations (Voronezh region), which...

Polysaccharide mucilage derived from the seeds of Plantago major L. (family Plantaginaceae) was investigated for use in matrix formulations containing propranolol hydrochloride. HPMC K4M and tragacanth were used as standards for comparison. The hardness, tensile strength, and friability of tablets increased as the concentration of mucilage increased, indicating good compactibility of mucilage p...

For thousands of years in Asia, Althaea rosea Cavanil (ARC) and Plantago major L. (PML) have been used as powerful non-toxic therapeutic agents that inhibit inflammation. However, the anticancer mechanisms and molecular targets of ARC and PML are poorly understood, particularly in epidermal growth factor (EGF)-induced neoplastic cell transformation. The aim of this study was to evaluate the che...
