abstract background antibiotic resistance makes antimicrobial peptides (amps) agents an alternative for treatment of pathogenic diseases. they are isolated from various animals invertebrates, vertebrates and plants. the present study shows the electrophoretic pattern of protein and peptides from vicia faba seed and reports our first attempt to study the antibacterial activity of vicia faba seed...

The effect of fluridone on the growth of plants and drought stressinduced abscisic acid (ABA) accumulation were studied in mature leaf tissue of Vicia faba L. plants grown under different light intensity. Drought stress was induced by allowing the leaves to lose 12% of fresh weight. Treatment of Vicia plants (grown at high light intensity – 600μmol.m-2.s-1) with 10μmoles fluridone caused a cons...

Disinfection of surface drinking water, in particular water chlorination, produces many by-products with genotoxic and/or carcinogenic activity. The aim of this research was to evaluate the genotoxicity of surface water after treatment with different disinfectants by means of in situ plant genotoxicity assays. The study was carried out in a pilot plant using lake water after sedimentation and f...

The exposure of mitotic or meiotic cells to ionizing radiation or certain drugs produces chromosome aberrations which appear as side-arm bridges at anaphase . The aberration has been so named because the bridge apparently involves a chromosomal strand smaller than either of the anaphase chromosome arms, i .e ., a subchromatid exchange (Nebel, 1936 ; Swanson, 1947 ; Crouse, 1954 ; LaCour and Rut...

A study of the metabolic pathways of H(3)-thymidine utilization in buds of Lilium longiflorum and root tips of Vicia faba was undertaken in order to obtain information that might explain the binding of H(3) from H(3)-thymidine in the cytoplasm of these plants. H(3)-thymidine was administered for various periods of time, the tissues were fixed and processed in the manner routinely used in prepar...

The genotoxicity of quinolone and fluroquinolones was assessed using the micronucleus (MN) test on Vicia faba roots by direct contact exposure to a solid matrix. Plants were exposed to quinolones (nalidixic acid) and fluoroquinolones (ciprofloxacin and enrofloxacin) alone or mixed with artificially contaminated soils. Four different concentrations of each of these antibiotics were tested (0.01,...

Interphase nucleoli from Vicia faba and Allium cepa meristematic cells are roughly classified into two categories: (a) those that commonly show a rather homogeneous texture (except for small light spaces of various sizes) and frequently contain dense particles 140 A in diameter; (b) those found more frequently in Vicia characterized by a very sharp boundary between a dense outer cortex and a mu...

Disinfection of surface drinking water, particularly water chlorination, produces by-products with potential genotoxic and/or carcinogenic activity. A study carried out at a pilot plant for drinking water disinfection of lake water revealed mutagenic activity of three different disinfectants (sodium hypochlorite, chlorine dioxide and peracetic acid) in different seasons using in situ mutagenici...

This paper gives a kinetic analysis of the K(+)-selective outward-rectifier (IK,out) in the plasma membrane of Arabidopsis thaliana mesophyll cells in terms of the Hodgkin-Huxley formalism. We compared the kinetic characteristics of IK,out in Arabidopsis with IK,out channels in three other plant species that were subjected to a similar analysis: tobacco suspension cells, Vicia faba guard cells ...
