Excellent preservation and new structural details can be demonstrated in rust-infected leaf tissue after high pressure freezing and freeze-fracturing. A tubular-vesicular complex was the most remarkable cytoplasmic structure obsetved in cells of tile bean rust fungus Uromyces appendiculatus var. appendiculatus during its establishment in its host Phaseolus vulgaris. In fungal ceUs undergoing in...

Induction of the isoflavonoid pigment, coumestrol (3,9-dihydroxy-6H-benzofuro-[3,2-c][1] benzopyran-6-one), in primary leaves of beans (Phaseolus vulgaris L. var Saxa) by ultraviolet (UV) radiation was used as a quantifiable marker for UV damage to a plant system. Coumestrol was induced only by wavelengths below 300 nanometers and its formation could be reversed by treatment with white, but not...

A pot experiment was conducted at Faculty of Education, Alzaiem Alazhari University, Sudan, during 2019/2020 to evaluate the effect Amaranthus viridis powder on emergence and growth Swiss chard (Beta vulgaris var. cicla). The set as a completely randomized design (CRD) with four replicates. In treatments incorporated into soil rate (0, 0.5, 1.0. 1.5 2.0% w/w) representing T1 (control), T2, T3, ...
