Chromosomes and nuclei isolated from neutral formalin-fixed Vicia faba lateral roots were treated with trypsin, pepsin, RNase, or DNase. Only trypsin affected the morphology of the chromosomes and nuclei. The appearance of the chromosomes after trypsin digestion indicated that each chromatid contained four strands that could be seen with an ordinary light microscope. The experiments are interpr...

Poly A(+) mRNA was isolated from Vicia faba leaves and translated in vitro using a rabbit reticulocyte translation system. From analysis of the total translation products, the major proteins synthesized in vitro were 32 kilodaltons and 20 kilodaltons. When antibodies to Vicia faba polyphenoloxidase were added, a specific immunoprecipitable protein was observed. This protein's molecular weight w...

Vicia includes several economically useful food and forage legume crops. Among these, are Vicia sativa (common vetch) and Vicia narbonensis (Narbon vetch). The present study was carried out to evaluate seventeen lines of V. sativa and six lines of V. narbonensis for adaptability and yield under Riyadh conditions. Parameters studied included days to flowering, days to maturity, plant height, see...

Antibiotic resistance makes Antimierobial peptides (AMPs) agents an alternative for treatment of pathogenic diseases. They are isolated from various invertebrate animals, 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 extract. The crude e...

REVIOUS experiments have shown that quantitatively the response P of chromosomes of Vicia faba in pachytene to X-rays is approximately the same as that of the same species at the onset of the somatic prophase (MARSHAK 1939a). CREIGHTON (1941) using methods similar to those employed in the Vicia studies found that meiotic chromosomes are only a sixth as sensitive as the mitotic chromosomes in Ch...

An abscisic acid (ABA)-insensitive Vicia faba mutant, fia (fava bean impaired in ABA-induced stomatal closure) had previously been isolated. In this study, it was investigated how FIA functions in ABA signalling in guard cells of Vicia faba. Unlike ABA, methyl jasmonate (MeJA), H(2)O(2), and nitric oxide (NO) induced stomatal closure in the fia mutant. ABA did not induce production of either re...
