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,...
Structure and Mode of Formation of the Nucleolus in Meristematic Cells of Vicia faba and Allium cepa
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 ...

The protein mobilization from attached and detached seeds of Vicia faba L. cv. Eresen 87 (Fabaceae) was investigated. While the total soluble protein content decreased, the free amino acid content increased during the 7 days germination period. Among the three proteolytic enzymes, only endopeptidase activity was found to be affected by the removal of the embryonic axis. Leucine aminopeptidase a...
به منظور شناسایی و معرفی رقم جدید ماشک از گونه پانونیکا تعداد 11 پروژه تحقیقاتی و آنفارم از سال 1383 تا 1392 در مؤسسه تحقیقات کشاورزی دیم کشور و ایستگاه های همکار اجرا گردید. بررسی سازگاری لاین ها نشان داد که لاین vp-sel 1332 (رقم لامعی) دارای کمترین متوسط رتبه در تمام محیط ها بود و این لاین با داشتن بیشترین عملکرد علوفه (3572 کیلوگرم علوفه خشک در هکتار)، جزو پایدارترین ارقام در محیط های مورد ب...
this study set out to investigate the effect of bio-fertilizers containing nitrogen-fixing bacteria and phosphorus on grain yield and yield components of faba bean. to this end a factorial experiment on the basis of randomized complete block design with four replications was conducted in behbahan region at south eastern part of khuzestan province of iran. the experimental treatments included ni...
