The changes in endoplasmic reticulum (ER) morphology during seed development have been followed using a thick section electron microscope technique. The tissues were stained with a zinc iodineosmium tetroxide complex which preferentially accumulated in the lumen between double membranes. Sections up
Recombinant DNA libraries were constructed for seven chromosome types isolated from two translocation lines of field bean (Vicia faba L.) with reconstructed karyotypes. The chromosomes were selected so that the set of libraries covers the whole V. faba genome more than once. Individual chromosome
A new method is described for the isolation of large quantities of Vicia faba metaphase chromosomes. Roots were treated with 2.5 mM hydroxyurea for 18 h to accumulate meristem tip cells at the G1/S interface. After release from the block, the cells re-entered the cell cycle with a high degree of
cDNA clones encoding cysteine proteinases from cotyledons of germinated seeds of Vicia sativa L. have been obtained by means of PCR. Degenerate oligonucleotide primers were designed according to conserved amino acid regions of known cysteine proteinases. The deduced amino acid sequences of the cDNA
We have demonstrated that the activation of apoptosis-like programmed cell death (AL-PCD) was a secondary result of caffeine (CF) induced premature chromosome condensation (PCC) in hydroxyurea-synchronized Vicia faba root meristem cells. Initiation of the apoptotic-like cell degradation pathway
We isolated a free-radical scavenger "water soluble protein (WSP)" from broad beans. Hydrocortisone (HC) is known to inhibit superoxide generation and was used as the reference scavenger. WSP was examined for its effect on antioxidation in young (PDL 20, 25% of the maximum life span) and old (PDL
A PCR approach with degenerate primers designed from conserved NBS-LRR (nucleotide binding site-leucine-rich repeat) regions of known disease-resistance (R) genes was used to amplify and clone homologous sequences from 5 faba bean (Vicia faba) lines and 2 chickpea (Cicer arietinum) accessions.
1. Inclusion of raw faba bean (Vicia faba L., minor) in the diet of growing chickens was shown to affect the performance of the birds and to produce a significant increase in the relative weight of the pancreas. This was attributable to dietary trypsin inhibitors. 2. Trypsin inhibitors also produced
Increasing industrialization of multi-walled carbon nanotubes (MWCNTs) would inevitably lead to their release into the environment and combination with heavy metals. However, studies concerning the combined effects of MWCNTs and heavy metals on agricultural crops are limited. Herein, effects and
Degenerate potyvirus-specific primers were used in the PCR to amplify cDNA representing a 335 nucleotide region of the coat protein gene in RNA purified from an uncharacterised potyvirus isolated from Roystonea regia palms in Queensland, Australia. The RNA was also detected by PCR in total nucleic
Degenerate oligonucleotide primed (DOP)-PCR has emerged as a simple and rapid method for representative amplification of highly complex genomic DNA from humans, mice and Drosophila. The present paper describes the adaptation of this method for use on a plant species, Vicia faba, with a large genome
Skeletal muscle is the metabolic powerhouse of the body, however, dysregulation of the mechanisms involved in skeletal muscle mass maintenance can have devastating effects leading to many metabolic and physiological diseases. The lack of effective solutions makes finding a validated nutritional
1. Diets containing a freeze-dried tannin extract from faba beans (Vicia faba L.) at concentrations of 0, 8 and 16 g/kg were fed to growing chicks and rats. 2. Chicks fed on the tannin-containing diets exhibited a high mortality and significant decreases in body-weight as well as lower food intakes
A synergism of colchicine and different cucurbitacins has been shown, to be a cause in the formation of ball-metaphases in Bryonia species. The bitter principles cucurbitacin L and I, dihydrocucurbitacin B, and tetrahydrocucurbitacin I, which were examined more closely with respect to their
ABSTRACT An isometric virus ca. 25 nm in diameter with angular contour was isolated from onion plants showing yellow leaf striping and necrotic tips. The virus was mechanically transmitted onto 28 species of indicator plants belonging to five families, viz. Amaranthaceae, Chenopodiaceae,
